There were 21 commanders-in-chief in the War of Liberation, 3 became generals, but one did not even have a military rank?
During the Liberation War, our army fought three victorious battles, and the troops were first reorganized into five major field armies, one field, the second field, the third field, the fourth field, and the North China Field Army. The subordinate units of the field armies were reorganized from the previous columns into the former columns, from the previous column of troops, but as the scale of the battle grew larger, legions were formed later, each of which consisted of about three or four armies.

During the War of Liberation, our army had one 18 regiment, plus three regiments of the Nationalist army, one regiment of 21. The corps commanders were basically all generals, but there were four special men, three of whom became generals and one of whom had no rank.
Looking at the three generals, the first general Chen Geng was the fourth of the ten generals, graduated from the Whampoa Military Academy, he was a general during the Great Revolution, he was the commander of the Fourth Corps of the Second Field Army during the War of Resistance Against Japanese Aggression after the end of the war, and he has always supported the Vietnam and Korean Wars after the founding of the People's Republic of China.
Second General Xu Guangda was the commander of the Second Corps of the First Field Army, and he was the first commander of the armored unit of the Chinese People's Liberation Army. He was also a representative of the Red Second Front, and was therefore awarded the rank of general.
The second was General Xiao Jinguang during the War of Resistance Against Japanese Aggression, who was the commander of the Left Behind Regiment of the Eighth Route Army. During the Liberation War, he was the commander of the Twelfth Army of the Fourth Field Army. He was awarded the rank of general.
The only one who was not awarded the rank was General Cheng Zihua, who was also a cattle man. During the period of the Nengwen Nengwu Land Reform, he was the superior of the general Xu Haidong. However, due to the shortage of cadres in other positions after the founding of the country, he left the army system and lost the award title.
