In the Eastern Jin Dynasty, there were comments on Liezi, which were made by Lady Yi and Song, and Yun Liu's words were genuine and pointed. These four men were all famous metaphysical figures in the Western Jin Dynasty, and Wang Yifu was Wang Yan (256 ~ 3 1 1), a leader. The activity period of Liu Daozhen and Le Guang is about 280 ~ 304 [7]. Metaphysical scholars like to debate celebrities, and they like to debate GongSunLong, the greatest famous scholar in the pre-Qin period. These two questions are not in GongSunLong's posthumous work. They should have read Liezi. What Zhang Zhan said should be found in the literature at that time, which was the main source of Shi Shuo Xin Yu later.
During the pre-Qin period in China, the shooting technique should be highly developed, and it is easy to have ingenious shooters. Bows and arrows were produced in primitive hunting times, and long-term experience will accumulate rich shooting skills; Moreover, compared with other countries on earth at that time, Xia, Shang and Zhou were big countries, and shooting activities involved a large population, which would promote the development of shooting technology. In addition, during the Spring and Autumn Period and the Warring States Period, mergers continued, wars raged, and shooting activities were more extensive than in other times. Therefore, in the Eastern Zhou Dynasty, it was easy to see the mysterious shooter and mythologize the mysterious shooter in history. "Mencius" mentioned Yi He, "Lv Chunqiu" mentioned Gan Fei, indicating that there were some mysterious archers in the middle of the bow and arrow era who did not respect their legends and traditions. They should be deified among the people.
Moreover, in the pre-Qin period, the shooting skills of China and Turkey have developed to the point where professional works can be made. In the Book Biography, it is said that there are two pre-Qin bamboo books unearthed in the second year of Taikang, namely, the book of salary, on the easy shooting method. There is not much technical space about shooting, so it is generally difficult to write a book, and there are few monographs about shooting in ancient times. The basis of the monograph on shooting technology can only be that the shooting technology is highly developed and meticulous. Some pre-Qin techniques, such as Gou Jian's sword casting technique, were inferior to later generations. Since the Han Dynasty, there has been no monograph on archery, which shows that China's archery skills in the pre-Qin period were highly specialized.
