There are two main reasons:

First, Gao Yuliang made mistakes in principle, but Dakang Li didn't. In the process of the "116" incident in the play, Dakang Li had a lot of problems. Ding Yizhen bought and sold land under his banner, which made the Jingzhou area a mess. But Dakang Li, as the boss, ignored it, and even told Sun Liancheng how to sell the land afterwards. However, these things don't mean anything. Secretary Da Kang didn't make a principled mistake.

Gao Yuliang, on the other hand, did whatever it took to get rid of Dakang Li in Luzhou, and directly signed a food city project with Zhao Ruilong. This is also an important reason why Gao Yuliang stumbled. This project not only polluted the Crescent Lake, but also made the people nearby miserable. Over time, it became a well-known story.

second, Dakang Li dares to draw a line with Zhao Lichun, but Gao Yuliang doesn't dare, afraid of his hands and feet. After the food project, the relationship between Dakang Li and Zhao Lichun became more and more estranged, and there was basically no contact. Later, Dakang Li's entry into the Standing Committee was not recommended by Zhao Lichun. The main purpose of Sha Ruijin's coming to Handong was to punish Zhao Jiaban. In this respect, Sha Ruijin was relieved of Dakang Li.

Gao Yuliang signed the food city project, and there is no turning back. He can't clear the boundaries with Zhao Jiahua, and there is another definite factor: his real wife Gao Xiaofeng.

In in the name of people, the role of Gao Yuliang can be said to be a perfectionist. There is no room for any imperfection in his eyes. In order to pursue this so-called perfection, he will do whatever it takes or even lose the final bottom line. Until secretary Yu Liang finally took it away, he still didn't realize his mistake, and he even found a complete theoretical basis for all his actions.
