Science, Technology, Thought and Literature in Pre-Qin Period

Try to answer, this is just my humble opinion. Pre-Qin science and technology thought of two people, one is Lu Ban and the other is Mozi. The former invented the saw, and his wife is said to be the inventor of the umbrella. Mohist theory is mainly about materialism and science, and it is the representative of theoretical science in pre-Qin period. Lu Ban and Mozi also attacked the city, and Mozi invented the ladder. The premise is that the use of iron improves productivity, the well field system collapses, and the central government declines, forming a competitive situation. In order to finally unify the various schools, there are 39 schools: Confucianism, Mohism, Fa, Tao, Ming, Agriculture, Yin and Yang, Vertical and Horizontal, Miscellaneous (and novelists). Laozi: inaction, small country with few people, invisible way, "governing a big country is like cooking small fresh food"; Confucius: self-denial, benevolent love 5 Confucianism, Mencius: benevolent government, the people are noble and the monarch is light; Legalists, Shang Yang and Han Fei Lisi: severe punishment and strict law, centralization, emphasis on agriculture and suppression of business; Taoism and Zhuangzi: the same origin of things; Military strategist, Su Yi: He Zong Lian Heng; Saint Lv Buwei: Lv's Spring and Autumn Annals draws on all others' strengths.
