Yang Chengwu is an outstanding general of "dual superior military and political" in New China. He is a good at doing political work and military work.
After the founding of New China, it was highly valued. In the 1950s, it held three important positions, deputy general manager, commander of the Beijing Military Region and commander of the Air Defense Force; in the 1960s, it served as the first deputy general manager, acting chief of the military service group, and was responsible for the daily work of the army.

1952, Yang Chengwu returned to China from the Korean battlefield, returned to the North China Military Region, serving as the Chief of Staff, and presided over military work. Since the end of 1937, Yang Chengwu has been working under the direct command of Nie Rongzhen, opening up the Jin-Cha-Hebei base for 12 years. I am very familiar with the cadres and troops of , Jinchaji, and have prestige.
Nie Rongzhen is also the acting chief of staff, and he has no time to take care of the daily work of the military region. He is responsible for carrying out specific work as the chief of staff. Later, as usual, the chief of staff of major military regions served as deputy commanders and could be fully responsible for the work of the military region, and he was no exception.
In 1955, the North China Military Region was changed to the Beijing Military Region. He served as deputy general manager and commander of the Beijing Military Region. In addition, the prevention and control forces were changed to the air defense force, which became five major military branches along with the land, sea, air and public security forces. He served as commander.

In the 1950s, it was really rare for generals to hold three positions.
Since 1958, his position has been adjusted and he finally only served as executive vice chief of staff and participated in the daily work of the General Staff. He was just a name for the previous four years.
In 1965, Luo Ruiqing left the position of chief chief, and he was appointed as acting chief chief, which can be said to be highly valued because the previous few leaders were either marshals or generals, such as Xu Xiangqian, Nie Rongzhen, Su Yu , Huang Kecheng , and Luo Ruiqing.

He serves as the acting chief and respects generals of the same level very much, especially those with older qualifications.
In July 1966, he led the General Reference Inspection Team to conduct an investigation of the northwest region. As the commander of the Guangzhou Military Region, Huang Yongsheng , also participated in the investigation. The specific reason for him to participate is unknown.
During the survey in Xinjiang, Production and Construction Corps prepared several jeeps, only one newly produced "Beijing 212", and the others were all made by Soviet cars. The good car was prepared for Yang Chengwu, but he just wanted Huang Yongsheng to ride it. The reason was very simple: you are on Jinggangshan , I am at the foot of Jinggangshan, and you should ride a new car.
is in line with the positions of the two, but Huang Yongsheng joined the army early, and he served as a regiment and division position in Red Army earlier than him.

Huang Yongsheng participated in Autumn Harvest Uprising in 1927, went to Jinggangshan and joined the party. The Red Army was the division commander before the Long March .
Yang Chengwu joined the Communist Youth League in 1928. In 1929, he participated in the peasant riot in western Fujian and joined the Red Army. In 1930, he joined the party. When he joined the Red Army, the Red 4th Army had already come down from Jinggangshan and developed a base in the Fujian-Jiangxi region.
Yang Chengwu also held a regiment position during the Long March and was promoted to a division position after arriving in northern Shaanxi. Judging from joining the army, joining the party and position, Yang Chengwu was later than Huang Yongsheng. Starting from , the Anti-Japanese War, , the two have equal positions.

Yang Chengwu presided over the General Staff for three years and left his post in 1968 due to an impact. Some people suggested that Huang Yongsheng be appointed as the chief and the head of the service group, responsible for the daily work of the Military Commission .
