Behind the Huaihai Campaign was the material and human support of more than 5.4 million ordinary people in Jiangsu, Shandong, Anhui and Henan. Many villages went to the front line and even shouted the slogan of throwing caution to the wind to support the front line. It is said that in the third stage of the campaign, the ratio of soldiers to migrant workers in the rear reached 1 9, that is, there were nine migrant workers behind each soldier to support and defend the battle. After all, the eyes of the masses are discerning, and they all know who is good to them. It is said that those who win the hearts of the people win the world.
