At the end of Ming Dynasty, the slogan "All fields are tax-free" put forward by the peasant uprising army led by Li Zicheng was warmly welcomed by farmers. The main reasons include:

Political corruption: Political corruption was serious in the late Ming Dynasty, which led to poor livelihood for the people.

Land annexation: the land is highly concentrated, and a large number of farmers have lost their land and their lives are difficult.

Heavy taxes: heavy taxes make farmers unbearable and their lives are in trouble.

Therefore, when Li Zicheng put forward the slogan of "equal land without tax", it not only reflected the urgent needs of farmers, but also provided a way to solve these problems. This slogan has greatly aroused the support and welcome of farmers by promising to redistribute land and exempt from heavy taxes.
