Take the opportunity to travel to Nantong Haimen, and go to Jianghai Museum to learn about the local history in your spare time. A large number of prehistoric civilization relics have been found here, which is the intersection of Liangzhu civilization and the northern civilization of the same period. Modern times have appeared in China's earliest modern industry, which affected the direction of China later. Although this museum is not high-level, it can still learn a lot.
