It was after Qin Shihuang unified China (22 1 year ago) that the policy of "words in the same language, cars in the same track" was implemented, and Prime Minister Li Si was in charge. On the basis of the original characters of Da Zhuan script used in Qin State, it was simplified, and the variant characters of other six countries were cancelled, creating a unified writing form of Chinese characters. It was popular in China until the end of the Western Han Dynasty, and was gradually replaced by official script.
