1. In the early days, trees without owners could be cut down. However, in Zhou Liwang in the Western Zhou Dynasty, it was declared that all the mountain forests and Shui Ze were nationalized, and people were not allowed to get their hands on them. Originally, the king was nominally the master of everything in the country, but the people's firewood, fishing and hunting were not restricted. Therefore, Zhou Liwang's policy made people very dissatisfied and was abolished after being overthrown.
2. Two hundred years later, the reformer Guan Zhong took the lead in realizing the patent of Linshan Chuanze in Qi State, and regarded Linshan Shui Ze as the exclusive property of the monarch, which greatly increased the financial resources of Qi State and contributed to the prosperity of Qiang Bing. On the other hand, when the forests in mountainous areas of Shui Ze are regularly open for a short time every year, people can only make profits by logging, fishing and hunting.
