Li Chengyang sent Dong Yao a fake photo. Everybody knows at a glance that the relationship between Dong Yao and Ma Shuai is unusual before, and there is some kind of cooperative relationship. At the same time, combined with the plot, we can see that Ma Shuai's wife Li Lijuan also knows the secret of Dong Yao, so she is eager to cash out and escape.
At this time, Li Chengyang put pressure on Dong from two aspects by taking a photo of himself and Ma Shuai and asking questions from the supervision team in the morning. Even if Dong Yao is tenacious, he will try his best to clean up the stain of his past, which will definitely expose his trail and be followed by his opponent.
Li Chengyang found that Dong Yao and Dong Yao, as the mayors of Luteng City, had never done anything beneficial to the people, but tried their best to make money from themselves. Influenced by Gao Mingyuan's knowledge, Dong Yao did many bad things. The reason why Dong Yao is dead set on Gao Mingyuan is for money, because Gao Mingyuan is very powerful in Lvteng, and Dong Yao was hand-picked by Gao Mingyuan. On the surface, Dong Yao is loyal to Gao Mingyuan, but secretly he often wants to leave Gao Mingyuan. When Dong Yao was about to abscond with the money, he was caught by Gao Mingyuan.
After Ma Shuai's death, his wife Li Lijuan found Dong Yao and decided to cash out with the company's money. Li Lijuan just wanted to get more money and take her daughter away, but Li Lijuan was cheated by Dong Yao. Dong Yao's purpose in finding Li Lijuan is to hollow out Ma Shuai's group.
Conclusion Li Chengyang sent photos to Dong Yao, apparently pretending to be suspicious, trying to startle him and observe Dong Yao's actions. At this time, Dong Yaoxian was a little flustered and people became low-key. Then if he really has a problem, he must use his own strength and resources to erase the stain of the past and take action. As it happens, Dong Yao's actions are bound to be exposed under the surveillance of Li Chengyang.
