Men in the Warring States wore knee-length clothes decorated with continuous rectangular stripes, which was very consistent with the edge decoration of lacquerware vessels at that time. Men's wear is dominated by cross collars, narrow sleeves and belts. Compared with the early Western Zhou Dynasty, the hook in the Warring States period made great progress. They are made of gold, silver, copper, iron and jade. The hook is engraved with patterns and sometimes inlaid with turquoise to show its wealth. There is also a brand-new gold and silver handicraft with a more exquisite and luxurious appearance. During the Warring States period, the iron smelting industry was relatively prosperous. In addition to making copper knives hanging on people, the technology is also excellent. The small machete with a length of 25 cm is engraved with patterns, which is deeply loved by people, hence the name "Rong Dao". At this time, the hanging knife was not completely practical, and a large part of it replaced the records in Historical Records with decorations. During the Warring States period, an influential thing appeared. That is, the military uniform reform promoted by King Wuling of Zhao was later called "Khufu riding and shooting". It looks like a robe, with short sleeves and wide body, and is decorated with golden jade hooks. Later generations' evaluation of this pioneering work in the history of clothing is that practice produces true knowledge. Without the practice of war, if Zhao was not in a weak position at that time, there would be no military uniform reform. Therefore, some people say that the decisive change of Zhao from weak to strong is one of the important conditions.
