In fact, Zhang Dongsheng cannot be accurately defined as a good person or a bad person. He should be regarded as a person living in a gray area, neither a good person nor a bad person.

The scene at the beginning of the play is the scene of Zhang Dongsheng killing his father-in-law and mother-in-law. By taking pictures of them on the top of the mountain and throwing them down the mountain to death, the purpose was to use the death of the two old people to make his wife who wanted to divorce him give up the idea.The initial results seemed to be ideal, and things were progressing according to his plan. His wife became helpless due to the death of her parents and began to rely on Zhang Dongsheng again, and the good days began again.

Unexpectedly, his wife insisted on divorcing him after surviving the death of his parents. At this time, Zhang Dongsheng completely turned black. He thought that since he couldn't get it, he would just destroy it and no one else would get it. So he replaced his wife's daily food.Medicine, his wife died in the sea while going swimming. Although these people had something wrong, they were not killed by him and lost their lives. From these moments, it can be seen that Zhang Dongsheng is indeed a very bad person.
