According to archaeological evidence, the ancients in the Central Plains began to wear trousers in the Western Zhou Dynasty at the latest, and linen trousers have been unearthed in Guo Cemetery in Sanmenxia, Henan Province. The previous military reform about "Khufu riding and shooting" was falsified by the rumor that Zhao Haoqi Wuling of Zhao was in Handan (450-500 years earlier than Wuling of Zhao Haoqi).
The policy of "Khufu riding and shooting" was opposed by a large number of nobles in Zhao, and was abolished after the death of King Wuling. Moreover, as the influence limit of military reform on folk life, it is worth considering.
There are two kinds of trousers in ancient times: one is trousers; One is the cloud (Yi). Shuowen is not embarrassed but embarrassed, saying, "I am embarrassed, and my shin is arrogant." Cloud, Shuowen: "Cloud, heavy and thick, from the heart of the army (ancient muddy cutting) cloud or from the clothes." Sound and meaning are completely different. Sound, meaning and form are all the same.
The Book of Songs Qin Feng Without Clothes is a symbol of "sharing weal and woe with my son". Shuowen also said: "Yi, Yi also, saves the sound from the cold clothes", and Chunqiu Zhuan said "Yi, Yan (cutting away from filial piety)", so the four words "Yi" are the same or different in sound and shape. But it is used to wear tights.
