Why did Rui Xiaodan commit suicide in the TV series Paradise?

Xiao Dan died because his leg was blown off, and he was badly disfigured and bleeding. In fact, Rui's death was arranged by the author, which indicates that the disadvantaged groups will pay a painful price if they want to turn over.

Rui Xiaodan is the highest realm of this novel. Obviously, she can ignore the poor people in Wang Miao village like others, but she asks Ding Yuanying to give him a gift to help the villagers get rid of poverty. She knew that Ding Yuanying had this ability, and she obviously had German permanent residency, but she had to go back to China to be a criminal policeman.

Her German is very good and well-educated, but she stayed in a small county and became a policeman. Her annual dividend in the hotel is obviously more than her job, and she also helps others to do OEM work during the holidays. At dinner, I had a discussion with Ding Yuanying. Ding Yuanying said that he bought a house in Germany for 10 years in order to obtain permanent residency in Germany, but Rui Xiao Dan, who was completely different from him, returned to China early.
