When we were young, when we watched TV advertisements, we often heard that "Su Hu is full and the world is full". This is Jiangsu and Zhejiang provinces. In ancient times, it was very famous in Jiangsu and Zhejiang, because the richest people in the country were basically concentrated in Jiangsu and Zhejiang. Although it was forced to move south because of the war at that time, Jiangsu and Zhejiang, which eventually moved in, did not expect this treasure land. The terrain is mostly coastal plain, with fertile land, abundant water resources, abundant rain and rich products. Very suitable for life, and the war moved south, so the economic center of gravity moved here. Then it developed slowly.

Jiangsu and Zhejiang have convenient transportation. At that time, water transportation was very favorable, especially in Jiangsu and Zhejiang provinces. Look at the intersection of the Yangtze River and the Beijing-Hangzhou Grand Canal here. Also at the mouth of the Yangtze River, Anhui, Hubei, Sichuan and other places can be reached by boat. The Beijing-Hangzhou Grand Canal spans Jiangsu and the Yangtze River in Jiangsu.

All the materials of the imperial court arrived in Beijing by water, and the river was wide and easy to walk. Therefore, Jiangsu and Zhejiang provinces have developed commerce. Colleagues also gave birth to the development of many business gathering places and promoted the development of other industries, such as finance, service industry, handicrafts and so on. For example, Yangzhou and Huai 'an were developed by the Beijing-Hangzhou Grand Canal.

Jiangsu and Zhejiang generations come from the south, with fewer natural disasters and fewer wars. Why are there fewer wars? Because the main infantry and cavalry in ancient times, Jiangsu was densely covered with water networks and wetlands, most of which were paddy fields, which was very unfavorable for large-scale corps operations and cavalry to enter. Whenever there is a war, people can hide in the countryside with dense water networks and reeds. Therefore, during the war, the population lost less and recovered quickly.
