The First Field Army, the size of each army is much smaller than that of the Fourth Field Army, and there are only two corps in total, and there is basically no situation of inferior awards. Of course, there are still exceptions, and Yiye still has two generals with low military ranks, and they say that Yan Kuan wants and Liao Hansheng. 
Yan Kuo, as the chief of staff of Yiye, and an old revolutionary who joined the party in 1926, should at least have the rank of general. But why was he only awarded to lieutenant generals?Because he got it wrong at the time of his participation in the revolution!When assessing his military rank, the organization counted the time when Yan Kuyao joined the party as 1936, and it was true that Yan Kuang joined the Red Army in 1936, but he secretly joined the party as early as 10 years ago, mainly engaged in military movement work, and belonged to underground workers, so his identity has not been disclosed. At that time, information was not developed, which caused this error. Later, although the time when Yan Kuo was going to participate in the revolution was corrected, his military rank could not be changed. The other is Liao Hansheng, Liao Hansheng was originally going to be awarded the rank of general, but he was opposed by one person, this person is Mr. He. Mr. He and Liao Hansheng's wife's uncle, Liao Hansheng's father also served as a staff member for Mr. He, and the relationship between the two is extraordinary. But the closer the relationship, the more Mr. He had to avoid suspicion, so he took the initiative to apply for Liao Hansheng to only be awarded the rank of lieutenant general. Liao Hansheng was one of the representative figures of the Xiangxi Red Army, and if he did not confer the rank of general, he would need to choose another candidate for general, and this candidate was finally decided on He Bingyan. Indeed, according to his qualifications, he can only be said to be He Bingyan. He Bingyan's rank at that time was only at the level of the quasi-corps, and he was awarded a general, which belonged to a high award. 
There are two main generals awarded by Erye: Wang Jinshan and Yin Xianbing. Wang Jinshan is actually not too low, his rank is at the deputy corps level, and his combat exploits are also very powerful, but most of the deputy corps-level generals are awarded lieutenant generals. Of course, those with particularly outstanding military achievements will be awarded generals, such as Han Xianchu, Liu Zhen, Li Tianyou and others, all of whom are awarded generals at the deputy corps level. Of course, Wang Jinshan's military exploits are also very prominent, but compared with Han Xianchu and others, they are still a little worse, and their combat exploits are stronger than Wang Jinshan, and Tao Yong, who has similar qualifications, is only a lieutenant general, so Wang Jinshan's award of lieutenant general is logically low, but it is in line with the principle of awarding titles. Yin Xianbing was the first commander of the 16th Army, a brigade commander of the Eighth Route Army, and the commander of the 16th Army during the Liberation War. But he made a mistake in his personal style during the War to Resist US Aggression and Aid Korea, and was finally awarded the rank of colonel, which was indeed too low. But it can't be helped, after all, a mistake was made. Sanye's low-level awards are mainly Zhang Zhen, Tao Yong, and Wang Bicheng. Zhang Zhen is a deputy corps-level general and the chief of staff of Sanye, so he is indeed worthy of the rank of general. However, there is a hard indicator for the award of generals: to achieve the rank of full division during the Red Army. Zhang Zhen was only at the regimental level during the Red Army, and the gap was a bit big. Of course, Wei Guoqing, the general of Sanye, was also at the regimental level during the Red Army, and Wei Guoqing's situation was a bit special, he was the lowest level among the generals in the Red Army. 
Wang Bicheng is also in this situation, Wang Bicheng was brave and good at fighting during the Red Army, and his military achievements were extraordinary, but his rank was slightly lower, his highest qualification during the Agrarian Revolutionary War was only a deputy division commander of the Red Fourth Front Army, if he was a regular division, he still had a chance to be awarded a general, because his military exploits during the Liberation War were too prominent. However, because of the low seniority during the Red Army, he was finally awarded only lieutenant general. General Tao Yong was rated as a deputy corps level in 52 years, his combat exploits are the strongest among the commanders of our army's columns, and during the War of Liberation, his four columns (23rd Army) annihilated 200,000 enemies, which made the world look sideways. But his highest position during the Liberation War was only the commander of the 23rd Army, and he was not promoted to the rank of deputy corps until 1950. There are not many cases of Siye being awarded low, but there are still a few, they are: He Jinnian, Duan Suquan, Zhong Wei. He Jinnian was the commander of the Northwest Red Army during the Agrarian Revolutionary War, and the deputy commander of the Corps of Siye during the Liberation War. Of course, his younger brother He Jixiang was also awarded the rank of major general, according to He Jixiang's qualifications, it is not enough to be a major general, which can be regarded as a compensation for He Jinnian. 
Duan Suquan once left the team for two years during the Red Army, which was the reason for his low award, and according to his qualifications, he was worthy of being a lieutenant general. Zhong Wei was indeed lowered, because his subordinate division commander Wen Yucheng was a lieutenant general, but he was only a major general, as for the reason for his low award, it was mainly because of Siye's defeat in Qingshuping when he went south, which had the biggest impact on his award.
