Nuwa has developed a new type of musical instrument that can be used in a single tube or assembled to form a new type of musical instrument that can be used in a single tube or assembled into a large step forward in terms of technology and effect. The pen "Fun" Pavilion www.biquge.info ordered the Eling clan to make the capital city good management, which was used to regulate the music of the world.

"The great goddess of heaven, Nuwa, makes clay dolls out of clay and gives them life. Since then, Nuwa has created people, and people have multiplied and lived happily ever after. This is the legend of Nuwa's creation of man.

This legend illustrates that Nuwa invented pottery, which is made from clay. Nuwa is the originator of pottery and even porcelain art. At the same time, it also shows that the Youwa tribe, as the main female tribe, played an important role in the reproduction of human beings after the flood, and also represents that Nuwa standardized the human marriage system and established the matchmaker system, so that the reproduction of human beings has a moral norm from then on.

Pottery appeared in the Youwa period, and people could use pottery to cook, process, brew, and sterilize food. Tao Xun as a musical instrument also appeared in this era. The use of pottery has improved the living conditions of human beings, had a profound impact on the development of human dietary hygiene and medicine, and generated a large demand for food. Once planting technology and the need for plant seeds were combined, agriculture was about to emerge.

The primitive planting industry sprouted in the Fuxi era of using gourds as drinking utensils, and people first planted gourds, and in the process of planting gourds, people accumulated relatively rich planting techniques. In fact, when people start planting gourds, they don't necessarily think of planting gourds because of demand, it is likely that children start planting gourds out of hobbies and play. There are three reasons for this: first, children have a lot of free time to care, protect and manage the fruits of their "labor"; second, gourd seeds are large and white, which are loved by people; and third, gourd seeds are large and easy to sow seeds. In many places in our country, there is a custom of abstaining from eating gourd seeds, and adults will scare children with words such as "eating gourd seeds will grow teeth", which shows that people attach importance to and protect gourd seeds, and also hints at the long history of gourd cultivation. When our ancestors switched from planting gourds to growing grass plants for edible seeds, primitive agriculture was born.

"Saying Wen Jie Zi" cloud: "Lai" Manhua also, from the sound of the sound. Lai is mangrove, that is, quinoa, also known as red heart gray weed, the wild vegetables that the poor often ate in ancient times, and the other leaves can be boiled. Confucius is suitable for Chu, seven days are not hot, quinoa soup is not gritty, and the disciples all have dishes. "Lai" is one of the earliest edible staple food plants discovered by the Youwa clan and began to be artificially cultivated.

Nuwa introduced "Lai", which has been eaten as a staple food, to Nuwa City, and led the people to continue to carry out demonstration cultivation of other related crops with "Lai" as the mainstay, large-scale production, careful breeding, strengthening plant protection, purification and rejuvenation, and survival of the fittest. "Lai" eventually became one of the staple foods in the lives of the ancestors, and other crops such as wheat, millet, soybean, and rice were also successfully bred. With the ancestors' understanding of the production process and production links of "Lai" and other crops, the mastery of production technology and the natural evolution of "Lai" and other crops, the ears of "Lai" are gradually abundant, the grains are full, the seeds are large, the yield is increasing with the years, the taste is rich, pure and edible, and the edibility is extensive. As a result, the demand for the edibility of the seeds of "Lai" was wider, and the ancestors were more commonly eaten in their lives. The development of agriculture has brought about a guarantee for the people's livelihood and food. It has strengthened confidence in the development of agricultural production and promoted the determination to explore new agricultural varieties and cultivate grain seed sources.

There is a kind of weed growing in Nuwa City, and the ancestors called it Qicao. This grass is edible, it is not rare, and it is found everywhere in Nuwa City, so people do not cherish it very much. However, in the process of treating diseases, Nuwa discovered the medicinal value of this herb and named it Astragalus, which is the earliest Chinese herbal medicine.

During the reign of the Nuwa clan, a basic calendar was formulated: the seasons were basically distinct, the initial annual cycle was determined, the earth revolves around the sun once a year, and the sun moves once a year in the sky. The line in which the sun moves in this way is called the ecliptic. The sun, moon, and planets all move within a certain distance on both sides of the ecliptic, and at that time, the ecliptic was divided into twelve equal parts, called the zodiac signs, that is, the year was divided into twelve months, and there were four seasons in a year, and there were six festivals in a season. There are only 29 and 30 days in a calendar month. It is stipulated by the New Year, and does not contain human factors. The beginning of its year has strong astronomical significance, with the astronomical and mathematical cultural connotations of the solar year and the lunar month, and the yang season and the yin festival. It is the basis of the Chinese calendar. After thousands of years of practical application, it has been improved and enriched, developed and perfected, and finally became the lunar calendar (also known as: summer calendar, middle calendar, old calendar, commonly known as lunar calendar) used by people.

The lunar calendar is a fixed calendar, which has the characteristics of an astronomical calendar. It corresponds well to all kinds of celestial phenomena. For example, the relationship between the height of the sun and the temperature of the earth, the lunar day corresponds to the moon phase, the occurrence and non-occurrence frequency of leap months correspond to the perihelion and aphelion of the earth, the sunrise and sunset, the illusion of morning and dusk, solar eclipses, lunar eclipses, sea tides, and the solar height corresponding to the solar height. It provides valuable scientific data on weather and astronomy for the production of agriculture, animal husbandry and fishery of primitive ancestors. Therefore, because its solar terms strictly correspond to the height of the sun, it has the cultural connotation of "the unity of heaven and man" in harmony with yin and yang.

In the long-term collection activities, the women represented by Nuwa discovered the conditions for the growth and maturity of plants, and after repeated practice and understanding, they had an understanding of the laws of crop growth, and finally the rudiments of agriculture appeared.

In order to grow crops in large quantities, it is first necessary to select the right plant species and domesticate them into crop varieties, and Nuwa's introduction of Rai was a successful domestication process. The second is to master reserve tools, such as pottery, and the third is to master the agricultural time. All of this requires long-term technological progress and knowledge accumulation, and it is by no means possible overnight. During the Nuwa period, a set of methods for domesticating crops was developed, and the calendar was invented, which played a great role in agriculture.

In the early stage of agricultural development, the main technological progress is manifested in the domestication of wild plants, after tasting and trial planting, the ancients preliminarily determined several main weeds suitable for cultivation, the species of wild grasses vary from region to region, the harvested seeds are not only partially eaten, people will choose the full grains to be left as seeds, this is actually the domestication process of wild plants, so that the difference between cultivated plants and their wild original species is getting bigger and bigger, becoming crops.

Agriculture includes three steps: planting, harvesting, storage, and processing and eating. In the early era of gathering, fishing and hunting before the advent of primitive agriculture, harvesting and storing and eating were two completely independent processes, and the things that people collected and stored were not necessarily edible, and the things that people ate were often picked and eaten freshly, not necessarily what was previously stored, and the food that people stored was often not plant seeds.

With the advent of pottery, people had a safe and effective means of storage, so that they could store food and drinking water for a long time, so that the two independent processes of gathering, storage and eating were closely combined. Only in this case will there be a large demand for obtaining plant seeds. The saying that "starvation does not eat seeds" is very conducive to the selection and breeding of crop varieties.
