Cheng was also the founding general of the Tang Dynasty, but he ranked ninth among the 24 heroes in Lingyange. Obviously behind Li Jing, Li Jing is a genius who can use troops in history. He was also a general in the Sui Dynasty. Later, with the collapse of the Sui Dynasty and the fatuity of the Emperor of the Sui Dynasty, he began to work for the Tang Dynasty. He has won numerous victories in his life, and his life can be described as outstanding.
Besides fighting, Li Jing has a high level of personal thought and culture. He once wrote many military books, such as Mirror of Li Jing's Six Armies, which were later lost. Compared with Li Jing, Cheng is slightly inferior. At the end of Sui Dynasty, Cheng joined the Wagang Army, voted for the king, and then fell to the Tang Dynasty. His life is not as successful as Li Jing's, and he can count several battles.
Cheng may not be as good as Li Jing in fighting. Li Jing is a fighting genius. Compared with the courage of Li Jing, Cheng is a little worse. Li Jing used to be a general in the Sui Dynasty, and he was better at leading troops to fight than Cheng. At the end of the Sui Dynasty, Cheng only organized a team of several hundred people. And Li Jing is the commander in chief of the army, and his ability in operational command is definitely higher than that of Cheng.
Li Jing has accumulated a lot of experience in leading troops and experienced numerous actual combat. Cheng was only a simple exercise before, and there was no actual exercise. It can be seen that Li Jing's combat effectiveness is higher than Cheng's.
