Yao is a particularly selfish, vengeful and good at disguise in the play. He looks upright on the surface, but in fact he is dark inside. He is a complete hypocrite. On the other hand, his EQ is really high. At first, we all thought that Yao, like Zhou, was serious and responsible for his work, conscientious in his career and sincere to his colleagues and friends. He is a man full of positive energy. But with the development of the plot, Yao gradually changed from a disguised positive figure to a complete hypocrite.

? Feng Lei is a professional villain, and most of his plays have few positive roles. This time in On Earth, everyone thought he would be a positive character, but with the development of the plot, he gradually moved from a positive character to a negative character. On the surface, he is serious and responsible for his work, and seems sincere to his subordinate Zhou. When Zhou was in trouble, he also gave a lot of pertinent advice like big brother. In fact, he hides a lot of personal interests. When Zheng Juan and Luo Shibin quarreled and tore at each other because of their children's problems. Luo Shibin gave him a red envelope to let his children run before and after. When he used Zhou and framed him, he saw that he was actually a hypocrite who ignored his own interests.

Yao is very cunning in his work. He is good at using relationships to treat people, especially insincere. He had some power when he was in the ordnance corps. Many educated youths have to go to them to sign in order to return to the city. Yao used this power to molest many female educated youth, including Xiaodong. In order to keep Xiaodong with him, he took advantage of his position and lied to Xiaodong that he had children. It can be seen from here that there are also some problems in his character.

In Yao's cognition, friends are all used, and there is no moral benevolence in their hearts, only selfishness. He can make friends in order to get benefits from Luo Shibin, and he doesn't care about friendship.
