3. Which of the following Chinese documents fully records the practice of men farming and women weaving while raising silkworms?

The most complete record of men farming and women weaving and raising silkworms in China is "The Picture of Silkworms and Weaving".

During the Shaoxing period of the Southern Song Dynasty, Yuqian County Magistrate Lou Jin used his superb artistic skills to draw a painting based on his long-term observations and experiences in agricultural production, which is known as "China's most complete painting scroll recording men farming and women weaving" - "The Picture of Farming and Weaving". This painting fully reflects the two important production links in my country's agricultural era - farming and weaving.

The painting of farming and weaving contains 21 pictures of farming and 24 pictures of silkworm weaving. After the painting was completed, Lou Jin presented it to Emperor Gaozong of Song, who praised it and ordered the Imperial Academy to copy it. The original painting of farming and weaving and the painting of farming in its copy have been lost, while the original painting of silkworm weaving in the copy has been hidden in the imperial harem since the Song Dynasty. It was scattered among the people during the Republic of China and later owned by a citizen of Daqing. It was donated to the Heilongjiang Provincial Museum in 1983.

The Silkworm Weaving Picture, which mainly depicts working women in ancient times, is a series of atlases that record silkworm weaving in detail in the form of drawings. It comprehensively depicts the silkworm weaving production process of mulberry planting, silkworm breeding, and cloth weaving in ancient my country 800 years ago, and is embellished with social customs, with a strong sense of life. It is 1,100 cm long, with a center width of 27.5 cm, a length of 518 cm, and a postscript length of 460 cm. The first part of the painting is stamped with "Qianlong Yulanzhibao", "Shiqu Baoji", "Sanxitang Jingjianxi", "Yi Zisun", "Yu Shufang Jianzangbao", and the last part of the painting is stamped with "Jiaqing Yulanzhibao", "Xuantong Yulanzhibao", and "Jiaolin Liangshi Shuhuazhiyin". The painting has a grand scene, with a total of 24 small pictures, no title poem, but each small picture is accompanied by an explanatory text written in small regular script by Empress Wu of Song Gaozong.

The painting style of "Silkworm Weaving Picture" is realistic, showing that in the early Southern Song Dynasty, the silkworm weaving households in the eastern Zhejiang area went from "bathing in the twelfth lunar month" to

The first half of the scroll depicts the silkworm breeding process from "Silkworm Bathing" to "Storing Salt Cocoons in Jars", with a total of 16 pictures depicting the silkworm breeding process; the second half, except for "Silkworms Emerging" and "Thanking the God for Silk", shows the silk reeling and brocade weaving process. In the whole scroll, whether it is the depiction of the characters' expressions, clothing, hairstyles, and gestures, or the outlines of silkworm weaving utensils, houses and trees, all of them are simple and lifelike. It is precisely because of this vivid, delicate and vivid depiction that it has become a very precious artistic treasure and a masterpiece handed down from generation to generation.

7. What methods can be used to record silkworm breeding?

Silkworm breeding records can be recorded in the form of a diary to record the daily growth and changes of silkworms. Silkworms slowly hatch from small black seeds and grow up little by little. Recording this process can exercise children's observation ability and cultivate children's patience. In the growth of silkworms, children sometimes need to learn some knowledge by looking for information. Parents should support and help their children.
