Source: On Mencius and Li Lou by Zou Mengke in the Warring States Period: "It is smart to stay in a building, but it is smart to lose a child. If you don't follow the rules, you can't go around. The six laws are difficult to correct without five tones. "
It means: "A discerning eye like Li Lou and a skillful craftsman like a loser can't draw Fiona Fang without following the rules." If you don't follow the rules, you can't circle; Shi Kuang's cleverness is not based on six laws, let alone five tones; Yao and Shun are not benevolent and cannot govern the world.
Without rules, there would be no Fiona's square, which is a Chinese vocabulary, and the pinyin is wú gu and J ǔ BCH é ngfā ngyuá n to describe that without rules, there would be no formal Fiona's square.
