How are the regions of China distinguished, such as East China and South China?

The regional division of China is related to the regional management system of party, government and army integration from the Liberation War to the early days of the founding of New China.

At that time, there were six regions in China, namely North China (code 1), Northeast China (code 2), East China (code 3), Central South China (code 4), Southwest China (code 5) and Northwest China (code 6).

After the Northeast Field Army liberated the whole Northeast, it was ordered to enter the customs to liberate the whole North China and was renamed the Fourth Field Army. Later, it cooperated with the Second Field Army and the Third Field Army to carry out the battle of crossing the river, merged with the Central Plains Military Region, and liberated Hubei, Hunan, Guangdong and Guangxi successively. The Central Military Commission immediately agreed to rename the Central Plains Military Region as the Central South Military Region, and then the Central South Military Region liberated Hainan Island.

Shandong Field Army and Central China Field Army merged into East China Field Army, which was later renamed the Third Field Army. They took part in the battle of crossing the river, liberated Nanking, Shanghai, Hangchow and Fujian, and prepared to liberate Taiwan Province Province.
