The problem of excrement is solved, but the cleaning problem of the tribe members has not been solved. From later generations, we can know that people who do not pay attention to personal hygiene, such as developing bad habits such as not washing hands, will cause asthma, allergies, meningitis, heart disease, diarrhea, cholera and pneumonia, etc., will not only greatly reduce the chance of getting these diseases, but will also be responsible for the people around you.

The manufacturing of soap is not difficult for humans to wash animal fat and wood ash (alkali) soap for thousands of years. The difficulty in making soap is the ratio of fat and alkali. The traditional method is to prepare 1:5. In addition to letting the tribesmen collect the fatty oils that they don’t need when slaughtering livestock and wild animals, Huaxi also personally took Huayong’s logging team to the forest to find trees from the Pineaceae family to cut oil and oil shirts. Pineaceae and other pineaceae are all oil-rich plants. Pineaceae trees can also be said to be the most diverse species in the world and have the widest breeding and growth areas. Therefore, collecting and making soap oils is not a problem for Huaxi.

The prerequisite for making soap is that there must be a pot, and ceramics are the most important task Hua Xi will do next

Every day, excrement from humans and livestock is continuously pulled into the fields for land use; the hunting efficiency of the hunting team is also stable at about 2,000-2,300 kilograms, which not only meets the daily needs of the tribe, but also has a small amount of surplus to serve the food reserve to cope with the upcoming winter. The cutting team led by Huayong also cut down trees and stockpiled them on the river bank next to the farmland according to Hua Xi's instructions.

As the affairs of the elder Hua'an became increasingly complicated, the matters that needed to be contacted and handled gradually increased Hua'an's efficiency in service and the methods of responding to emergencies became increasingly sophisticated and mature. At Hua'an's request, Hua Xi approved Hua'an's request to ask for a few smart and capable tribe members as assistants without hesitation. From Hua Xi's perspective, as the ethnic group continues to grow, the matters that need to be handled will become more and more arduous, and at that time, the demand for talents in internal affairs management will be great. At this time, it is something that any organization will do well in talent reserves.

In addition, not only the reserve of management talents, but also the demand for talents in other aspects will become more prominent as the tribe grows. Hua Xi has now begun to consciously cultivate talents in all aspects

It takes two or three months to maintain the farmland. You can also plant the last stage of late rice before August. The growth is very fast, at most one year, and at most three to four months. It can sprout, bloom, and complete the fruit harvest process. As long as the planting is properly, it is expected that you will be able to eat delicious white rice before spring next year.

During this period, Huaxi had to solve the same big problem in ceramics! The use of ceramics is so wide that Huaxi doesn't know how to describe them, but the application of ceramics is not only used in daily use, such as tableware, tea sets, jars, jars, basins, jars, jars, etc., and can also be made into vases, sculptures and other artistic furnishings. It is not certain that it can also play an immeasurable role in some aspects.

What is more important is that the application of ceramics means that it will play a revolutionary improvement in the living conditions of the tribe. Improve the food cooked with ceramics is not only not as hot as barbecue, but also has a better taste, greatly reducing the digestive pressure of the stomach, and the effective absorption of food nutrition is easier. The benefits of such a series of chain reactions are naturally that the probability of people suffering from illness is greatly reduced, and the body is stronger, and the subsequent increase in the average life expectancy.

Huaxi knows that ceramics are made of clay or a mixture containing clay, formed, and calcined. Various processes and materials are used in high-end ceramics. Huaxi cannot make them, but Huaxi is confident that it can still make them.

In the valley, several tribe members cleaned the ground and cleaned the toilets where people came and went; several old men with gray hair were leaning against the stone wall to look at the lively and active children. A warm picture of Hua Xi’s greatest love in his heart. He must take his tribe members to live a good life without worries, and it is not in vain to come to the primitive society.

Before making pottery, Hua Xi first had to do to have his own personnel team. Why? God knows if those who learn to make pottery will jump to other tribes on one day. Although this is not a big possibility, it is not advisable to prevent it. It is not advisable to teach ceramics. It is enough to control it within a few people. Hua An, Huayong and two other tribesmen were nominated by Hua Xi to participate in the entire process of learning ceramic manufacturing. Originally, Hua Feng was also on the list, but the tribe's food stability still needs him to ensure that it is stable.

To make pottery, first of all, there must be clay. The source of clay is not a difficult problem. It is related to the wide distribution of clay in the world. The figure of clay can be seen almost everywhere. After finding a few barrels of clay from the forest, Hua Xi began to take the step of making pottery, that is, to deal with pure clay.

First, pour the clay into a wooden plate, then fill it with water and use the method of removing sand and gravel. What is left is naturally pure clay. Then I pinched five regular earthen pots with my hands, and randomly made some patterns on the pot body, then dried it naturally or dried it. Finally, it was calcined. However, the pot made of adobe needs some time to naturally dry it. Taking advantage of this time, Hua Xi and Hua Yong built a few kilns that were about to grill ceramics in a while.

The minimum calcination temperature of ceramics must be around 700-1000 degrees Celsius. If you want to calcinate higher-quality porcelain, you must have a temperature above 1200 degrees Celsius. With the current technical productivity, it is really difficult to reach that kind of high temperature, but at least this temperature is barely possible.

The building of the kiln is not too troublesome, it just takes time to spend Hua Xi first digging a soil pit of more than 20 cm high on the ground at the upper air outlet, and then quickly build a 150 cm high and one meter wide kiln ceramic is an excellent refractory material and has extremely high heat resistance. Therefore, the kiln made of clay will be a ceramic product in the future. The kiln is divided into two layers. The bottom layer is firewood, and the upper layer will naturally place the clay that needs to be calcined.

The top of the kiln is open air, but when burning the kiln, Huaxi will put a piece of clay and dry thick lid. There are several small holes in the middle of the lid to vent. This closed kiln. When burning, a large amount of carbon monoxide produced by the fire is blocked by the cover above the kiln and squeezed into the kiln. The rapidly rising air pressure will inevitably accelerate the high temperature produced by carbon monoxide. You must know that the temperature of carbon monoxide is much higher than that of pure firewood.
