"The History of China's Food Policy" uses a vertical and profound historical perspective to carefully sort out the evolution of China's food policy over thousands of years. Like a mirror that reflects social changes, it deeply analyzes the core and details of agricultural policies of past dynasties, the ups and downs of the grain taxation system, and various food initiatives related to people's livelihood and well-being. It also reflects the ups and downs of economy, culture, and politics in the long history of China.
