The iron-locked cliff is more than 120 meters high, and there is a dark crack that runs through the entire rock from top to bottom. From a distance, it looks like two huge portals standing by the water. Since ancient times, the iron-locked cliff is a door. After opening the door, it is Jinshanyuan with infinite treasures.

There are many legends about Jinshanyuan. The earliest one is that there must be twelve brothers who work together to open the door. It is said that there are eleven sons and a son-in-law of the family. One night, when people went to visit the treasure, they pushed open a crack in the heavy cliff stone gate and saw the shining golden light inside.

The youngest son was anxious at the time and wanted to get in alone, so he shouted, "Brother-in-law, work harder!" Then he let go of his hand and drilled into the crack of the door. As a result, the door was closed instantly and they could no longer push it open.

There is also a legend that the gate of Jinshanyuan must be opened on the full moon night, and the key must be found. The key is said to be an ancient vine on the cliff.

It is said that someone climbed the cliff on a full moon night. In the moonlight, he saw a long rope-like vine stretching out of the rock gap. He reached out to pull the vine, and the cliff gradually opened. Just when he was happy, the vine broke and the man fell off the high cliff...

As for the most widely circulated story in the local area, it is like this: there is a poor guy who is a filial son who lives with his mother. One day, he came back late to get firewood. After dark, he got lost. He suddenly saw a courtyard made of gold in front of him. The walls of the courtyard were made of gold bricks and the roof was paved with gold tiles.

When the young man walked into the yard, he saw an old woman pushing a mill to grind a big shred. The so-called big shred is cornmeal with coarse grains. The young man asked the old woman where this place was and how to get out. He rushed home to cook for his mother. The old woman told him that he could find the way by walking forward when he went out, and asked him what help he needed?

The young man just wanted to ask for some food from the old lady, so the old lady grabbed the corn kernels on the mill and put them in a bag. The young man carried the bag home, but he didn't find a hole in the bag, and he sprinkled it all the way... As a result, the next day, people found that the road outside the village was full of golden beans, and the young man also found that the corn kernels he carried home turned into golden beans.

There is a village called Manjinyu Village in the local area. It is said that the name of the village comes from this legend. There is a saying circulating in the surrounding area - opening Jinshanyuan will make you rich in the nine provinces and eighteen counties.

Since Zhu Shanxian and others found the place, they also investigated the local history and legends. When they came to the Iron Lock Cliff by the Juma River, they were still talking about the local stories. This day was the 26th day of the 1st month of the Gregorian calendar, and in two days it was the 23rd day of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the 1st month of the

It was already winter, and it was the coldest time of the year. The Juma River was in a dry season. The water surface in Qianwan was frozen and the cold wind was blowing under the cliff. Zhu Shanxian, Tan Hanchuan and Shang Ni walked along the river beach with big travel bags, but they did not see where Zhuang Mengzhou, Ding Qi, and Xian Hao were.

Tan Hanchuan told various local legends and stories, and Zhu Shan laughed: "If the legends of gods, ghosts and foxes in Strange Stories from a Chinese Studio are the fantasy of literati, then the legends of entering the mountain such as Jinshanyuan are the fantasy of rural villagers. Lao Tan, you are engaged in scientific research. Have you ever verified the meaning behind these legends?"

Tan Hanchuan replied: "Other stories are hard to tell, but the story of the golden beans will never appear too early, because corn was first introduced to China in the Ming Dynasty. It was almost the late Ming Dynasty to plant it in this area. It was already the time when it introduced high-quality varieties to plant them on a large scale. It was from the Qing Dynasty to the Republic of China.

The climate entered a Little Ice Age in the late Ming Dynasty. There was a large-scale famine in North China, mainly due to the lack of staple food. The so-called "Opening Jinshanyuan can enrich the 18 counties of Jiuzhou" is purely nonsense and wishful thinking. Jiuzhou is more than just the 18 counties? For the sake of rhyme, people in the past dared to make up any rumor, just like people who write lyrics nowadays.

Even if you really find a mountain of gold, it cannot solve the problem of famine at that time. Gold is just a general equivalent, and the gold picked does not naturally bring labor products. So the legend is a code word, and the so-called golden beans should refer to corn, a new staple food crop that just appeared at that time.

The yield of corn is high, and the climatic conditions in most parts of China can be cultivated. In North China, it can also be planted after spring wheat harvesting, which can harvest more grain for one season. More importantly, corn is not very picky, and several rows of them can be planted in the open space behind the room, and corn cobs and straw can also be used as feed.

In that era, under that circumstances, the newly emerged grain crops, whether they could fundamentally solve the problem of famine, also brought some hope to people. Therefore, the legendary golden beans actually symbolize corn kernels and contain people's expectations. The introduction of new grain crops was also one of the reasons for the population explosion in the middle of the Qing Dynasty."

Zhu Shanxian smiled again: "Columbus discovered the New Great Road, and he went to find gold, but the most valuable discovery was corn, which spread throughout the world. Corn is called Liugu in the countryside of ours, which means that there is another grain outside the traditional grain, which shows its importance."

Shang Ni continued: "In the northeast, it is called corn, also called bastard, which means being stupid. When our Northeast classmates laugh at people's stupidity, they often say - you corn."

Tan Hanchuan: "There are many such words in Northeast slang, such as sticks, roe deer, and tiaozi...all of them are all the same."

Shang Ni praised: "Senior Brother Tan is worthy of being a scholar. He became interested when he mentioned research and verification. I love to hear Senior Brother Tan say this the most. It's really a long-term learning!"

Tan Hanchuan said modestly: "If you talk about knowledge, I dare not compare with Mr. Zhuang."

Shang Ni: "Hey, where did Mr. Zhuang go? Didn't you agree to meet here? Why can't you even see his shadow? Are you still sleeping in?"

It was just past nine o'clock in the morning. It was still early in the cold winter day, and no one wanted to get up and run to the suburbs. There were no tourists by the Juma River. On the river beach under the iron cliff, someone was walking with his hands on his back, muttering and wondering what he was complaining about. He was wearing a military coat, a cotton hat, and thick labor protection leather boots under his feet. He was wearing a red hoop on his left arm, with four yellow characters: Public security patrol.

When I saw this sleeve, I knew that he was not easy to mess with. This place was Fangshan District, Beijing. If it were replaced by Chaoyang District, it would be even more unaffected. This person is a local joint security guard. He is usually an uncle and aunt who is still energetic after retirement. He will also hire idle villagers nearby in the suburbs.

The joint defenseman may be complaining that the weather is too cold. His cotton hat is pressed very low, with cap ears hanging on both sides, and his hair is invisible. He wears a pair of old-fashioned thick-framed glasses, and his face is dark and it seems to be covered with stove ash. It is indeed not easy to run here early in the morning to patrol, but looking at the back, his waist is very straight, and his body is quite strong.

The Juma River was called Laishui in ancient times. The Iron Suo Cliff in ancient times was also a scenic spot. The water flow rushed to the cliff and formed a huge whirlpool. The waves were unfathomable and were called Longtan by the locals. Whenever the rainy season, the water flow on the cliff converged into long white waterfalls and leaked into the pond. "Long'an Night Rain" was also one of the so-called "Eight Scenerys of Laishui" in ancient times.

Now, artificial rivers and embankments have been built in this section of the Juma River. Real estate development is still underway not far from the other side of the Iron Lock Cliff. The wide river berth has disappeared and the Longtan has been filled. The water flow of the Juma River has obviously become smaller, and a river beach is also exposed under the Iron Lock Cliff.

This is not a scenic spot. Tourists usually go to the upstream Shidu. Such a large 100-meter-high cliff has become a place that many rock climbers often come to. They nail anchors on the rocks on the top of the cliff and hang ropes to practice rock climbing. When the weather is good, they can see many people climbing up and down every day, and there are many off-road vehicles parked nearby.

But most rock climbing enthusiasts come in summer, but now it's winter. There is no trace of a person on the river beach. What's the point of patrolling? The appearance of this security guard is a bit abrupt, but there are even more abrupt ones.

I saw another man walking downstream of the river. He was carrying a dustpan frame on his left shoulder and a long bamboo clip in his right hand. He was wearing an orange-red jacket with a reflective belt, which was a common cleaner dress.

The joint defense officer had just lit a Hongta Mountain. He looked up and saw the cleaner. He waved and shouted, "Oh, what are you doing? Why did you come here?"

The cleaner leaned over and smiled and said, "Uncle, I am responsible for the hygiene of this section of the river."

Joint Defense Officer: "When will there be cleaning here? Why didn't anyone tell me?"

Cleaner: "I am new to the town and hired by me. I just started working and you have never seen me before."

The joint defense officer seemed a little dissatisfied and said, "When there are too many people in summer, I don't ask for cleaning, but when there is no one in winter, I hire someone. What do the leaders think?"

The cleaner explained: "Do it in winter and in summer. If there are many people, you must keep a good hygiene and care for the environment."

The joint defenseman looked at him with a cigarette in his mouth and said, "You are here, what am I doing?"

Cleaner: "You are always responsible for public security patrols, and I am responsible for protecting the environment, so it will not be hindered."

Joint Defense Officer: "How much does the town cost you a month?"

This question seemed a bit sudden. The cleaner seemed to be unprepared. He was stunned and replied: "Not much, one thousand five per month."

The joint defenseman frowned and said, "It's only so much money? I see that you are young and you can't do anything. You can earn much more than you can get a job in the city. Why do you have to come here to drink the cool breeze?"

The cleaner explained again: "I happened to have something to do at home and can't leave for the time being. This is a job by the way... How much do you earn every month?"

The joint defenseman exhaled a puff of smoke and said, "I'm not convenient for you to tell you this. Even if you earn more than you, you don't have to be mentally imbalanced."

The cleaner was scolded for no reason, but he still laughed and said, "That's right, that's right, you did it earlier than me. In the future, I'll work together, please take care of me."

This section of the river beach is free of people and is very clean, and it does not require patrol or garbage collection, so the two of them simply stand by the river and chat. The cleaner asked again, "Are there many people coming here?"

Joint Defense Officer: "When the weather is good, there are a lot of people, and people often do rock climbing here. My patrol mainly reminds them not to litter, take away all the things they bring, and don't do anything to destroy, and don't go down the river to swim."

Cleaner: "So have you seen anyone come here a while ago?"

Joint Defense Officer: "Who comes from this cold weather? I have never seen anyone except you."

Just then, the cleaner raised his hand and pointed, "Aren't three people coming over there?"

It was Zhu Shanxian, Tan Hanchuan and Shangni, the joint defense officer stepped over and shouted, "What are you three?"

Shang Ni stepped forward and greeted, "Master,..."

Before she could finish her words, the joint defense officer retorted, "Your uncle! I ask what you are doing, come here in the cold weather?"

Why is this man talking so aggressively? Zhu Shanxian quickly stepped forward and said, "Master, we are here to play. What are you doing?"

The joint defense officer did not speak and proudly patted the red hoop on the left sleeve of the military coat. Zhu Shanxian: "Oh, you are patrolling. Thank you for your hard work in this cold weather."

Joint Defense Officer: "It is the responsibility of every citizen to consciously maintain social order. I am patrolling here to prevent suspicious elements. Who are you?"

Shang Ni said unhappily: "This place is not your home, can we play with it?"

The joint defenseman glared and said, "Run here to play in the winter? I didn't say no, I just remind you!"

Tan Hanchuan pulled Shang Ni and went up to say in a quiet voice: "Master, we are here to climb rocks."

The joint defenseman waved his hand and said, "Rock climbing? Who told you that you can climb randomly? Is there any evidence?"

Zhu Shanxian and others were stunned. They ran to the wild to climb rock climbing and had to apply for a certificate. This person's brain circuit was a bit strange! Shang Ni said dissatisfiedly: "Do you have a certificate or not?"

Joint defense officer: "Why aren't it my responsibility? You ran to the cliff here to hang ropes and wedges. This is to destroy the mountain and may cause rock collapse, which poses a safety hazard."

Tan Hanchuan explained: "We don't hit rock wedges on the cliff."

Joint Defense Officer: "That's not appropriate, there are still security issues. Who is responsible for any incident?"

Tan Hanchuan: "We are self-conceited and will never implicate you." As he said that, he took out five hundred yuan bills from his pocket and stuffed them into the hands of the joint defense officer. The joint defense officer did not return the bill, but he still looked at Tan Hanchuan without saying anything. Tan Hanchuan had no choice but to touch the five more cards and handed them over. The joint defense officer turned around and walked away with satisfaction.

The cleaner kept watching from the side, and then came over and said, "Master, you are so good, can you make money?"

Joint Defense Officer: "I just said, don't you have psychological imbalance, why don't you get two hundred?"

The cleaner waved his hand and said, "No, no, how can I share your old money?"

The joint defenseman put the money in his pocket and said, "Now there are people who go out to bring so much cash. Isn't it enough to transfer the money on WeChat? Well, there must be a problem, we have to keep an eye on it!"

The cleaner helped Tan Hanchuan and others explain: "It is normal for those who are doing hiking and wild tours to carry cash on them. They can't use electronic payment everywhere. There are no network signals in many places. Uncle, it's quite cold and there are no people. I'll just watch it for you. If you have nothing to do, go back and rest."

The joint defense officer said seriously: "No, I have to go over and remind them a few words, and then go back and rest."

Cleaner: "Then you are always busy. I am responsible for this large section of the river. I will go upstream first and come back."

After he finished speaking, he walked upstream and came to a secluded place and sent a WeChat message: "Boss, the target has appeared!" He also attached a photo he had taken quietly just now, which was about Zhu Shanxian and the other three.
