The person Tang Feng mentioned was Zhang Daqian. When it comes to the Chinese painting world, there are two well-known people, which have to be said, namely, the Southern Zhang and Northern Qi, and the Southern Zhang and Northern Qi refer to Zhang Daqian and Qi Baishi respectively.

Zhang Daqian's original name was Zhang Zhengquan, also known as Zhang Yuan, his name was Jiyuan, and his nickname was Daqian. He was also known as Daqian Jushi, a native of Xialiba, and his name was Dafengtang. He was the most legendary master of Chinese painting in the 20th century. He knew everything from painting, calligraphy, seal carving, and poetry. His painting style was fine brushwork, freehand brushwork, heavy color, and ink and color splashing techniques, creating a brand new painting art style.

"Hi, I should have thought it was Zhang Daqian long ago." Chen Yan said: "If it were his imitation, it would be more valuable than the original one."

To say that fakes are more valuable than genuine works, it does not mean that Zhang Daqian's painting skills must be higher than Shi Tao. This is based on the price trend of Zhang Daqian's authentic works. In 1994, China Guardian International Auction Company once auctioned a Zhang Daqian antique landscape painting. Although it was not a fine product, the transaction price was as high as 1.9 million yuan. The 1.9 million yuan in 1994 was much more valuable than the 1.9 million yuan in 2009.

Tang Feng then explained to them that Shi Tao's painting style is unique and it is difficult for latecomers to imitate. Most of the fakes are two-handed ones, with poor skills and easy to distinguish between true and false. The only one who successfully imitated Shi Tao was Zhang Daqian. His imitations were almost completely different from the real ones. This is why the two experts could not see the flaws at the beginning and mistakenly thought that this "Autumn Landscape Picture" was Shi Tao's original work.

The three of them were chatting and the meal passed quickly. Tang Feng and Lin Muyu packed the dining table together. Lin Muyu made tea for them and sat down. Of course, she did not forget the topic just now. She asked Tang Feng: "Then what is your basis?"

Tang Feng frowned and said, "This matter is hard to explain. When I first saw this painting, I thought it was Shi Tao's original work; after seeing the calligraphy and calligraphy, I thought it was a fake. Finally, I began to suspect that the painting was Zhang Daqian's antique painting. Because Mr. Zhang Daqian's calligraphy and painting seals before his later years were all carved by himself, I have conducted special research on several of his early calligraphy and painting seals. In this painting, the two calligraphy and painting seals, "Qingxiang Lao Ren" and "Yuan Ji Calligraphy and Painting", have many similarities with Zhang Daqian's early "Zhang Ji", "Zhang Ji Shi Shi" and "Aai" in handwriting and carving."

This is actually the method of identifying the style of handwriting, but Tang Feng's basis for confirming that this painting is Zhang Daqian's antique work is not limited to this. Tang Feng cannot explain many things clearly, and can only answer in a general way that Zhang Daqian's imitation of Shi Tao's paintings has reached the point of being both physical and spiritual, and is fake and real; compared with the imitation of the painting itself, Zhang Daqian's imitation of Shi Tao's calligraphy has been reduced to a level; compared with the imitation of calligraphy handwriting, Zhang Daqian's imitation of Shi Tao's seal carving has been reduced to another level. When these three levels appear on the same painting in a step-like shape, it is not difficult to judge the authenticity. But this is not the main basis for Tang Feng to identify the authenticity of this painting. One thing that even Tang Feng himself has to admit that his level within the scope of artistic appraisal is not as good as those two experts, but his technical appraisal is higher than those two experts.

Technical appraisal is the watershed between two completely different identification results. The texture of this painting is not paper but silk. Tang Feng played the most critical role in the technical appraisal of painting silk. The painting silk looks no different from ancient silk, but Tang Feng found traces of salt on the back of the painting silk, which is the trace left by the counterfeiting of painting silk. The method of painting silk is to soak the new silk in salt water for a period of time, then put it in clean water to remove the salt, and then expose it to the scorching sun. After repeated several times, the new silk can be like ancient silk from hundreds of years ago. But no matter how it is soaked in clean water, the salt stain cannot be completely removed. Over time, the trace salt stain will appear on the back of the painted silk.

Only Zhang Daqian can do this in the old paintings of the Republic of China, which are the same as Shi Tao’s original works. After the technical appraisal, the two experts and Tang Feng’s identification had different directions. The two experts were deciphering Shi Tao’s fakes, while Tang Feng was deciphering Zhang Daqian’s real works, with different directions and completely opposite results.

Although Tang Feng's words are plain and simple, Chen Yan and Lin Muyu still have some understanding of them. However, they are really happy for Tang Feng, as long as he can find a vacancy, it is a good thing.

The third night was the exhibition of the lots. In the afternoon, Tang Feng and Chen Yan came to Fan Chengru's house together. Shortly after ringing the doorbell, the door of the Fan family opened. The person who opened the door was not Fan Chengru, but the young woman Tang Feng met at the Beijing Antiques City last time.

"Brother II." The woman smiled slightly, and she looked at Tang Feng and asked Chen Yan: "Is it his Tian Huangshi?"

Tang Feng looked at the young woman without saying a word. She was really beautiful. She was not inferior to Lin Muyu and Liu Yue in terms of body shape, and she was even slightly better in temperament. However, Tang Feng was not in the mood to appreciate her. Last time she blamed Chen Yan for being troubled and making a stone make their old man possessed. Now, the owner of the stone is right in front of her, and she is completely likely to criticize Tang Feng.

"Yes, it's his." After Chen Yan introduced Tang Feng to the woman, he turned to Tang Feng and said, "She is my uncle's granddaughter, Fan Ziyun, the star host of the TV station."

Tang Feng nodded secretly, no wonder he was so elegant. It turned out that he had practiced in front of the camera. Fan Ziyun greeted Tang Feng with great elegance. After that, she looked back and lowered her voice and said, "Brother Erzi, have I told you a long time ago? Don't give our old man wine. He is in poor health, but he prefers to drink. Our family is banning alcohol in full."

Tang Feng had a fever on his face, and he had caused trouble again before he knew it. His grandfather was so happy that he naturally gave Fan Chengru cigarettes and alcohol.

"No?" Chen Yan shook his head and said, "We all agreed."

"Girl, what are you muttering?" Fan Chengru from here was still whispering, and over there walked out of the study. Fan Ziyun said softly: "Don't mention the wine. I confiscated the wine yesterday and was angry." Then, he set off a high volume and said politely to Chen Yan and Tang Feng: "Please come in, please come in."

The two walked into the Fan family and Chen Yan said, "Uncle Master, are you doing well recently?"

"Well, just that." Tang Feng left a good impression on Fan Chengru. He specially greeted Tang Feng and said, "Xiao Tang is here, sit down."

Tang Feng and Chen Yan sat down on the sofa next to the coffee table. Chen Yan and Fan Chengru's uncle and nephew met, and they could not help but ask about their well-being. Tang Feng here was anxious but could not express it, so he had to agree without saying a word.
