Introduction to the Seven Battles and Seven Victories: The Seven Battles and Seven Victories in Central Jiangsu, also known as the Battle of Central Jiangsu, took place from July 13 to August 27, 1946. Under the command of Su Yu and Tan Zhenglin, the Central China Field Army fought against American-equipped troops with 30,000 troops. The Kuomintang army, numbering 120,000, fought seven times in a row and achieved great success, wiping out more than 53,000 enemy troops. This battle wrote a model chapter in the history of Chinese wars in which a small number defeated a large number, accelerated the victory of the Liberation War, demonstrated the great strength of the Soviet Union's military and civilians, and demonstrated Su Yu's extraordinary military commanding ability.
