How to evaluate the movie Death Divination?

Question 1. The life and death of the protagonist, from the signs of life, it is obvious that the protagonist is still alive. She can break things, take scissors, run out, make a phone call, and see herself in the mirror (the undertaker said)

Mingji is just a soul. Theoretically, the soul can't see what is in the mirror. )

Question 2. The protagonist's view on the meaning of existence is from the perspective of the undertaker. He thinks that a person living is meaningless, only eating and drinking Lazarus, and can't prove that you are alive, just like a zombie.

Question 3. The core problem is that a person should find his own goal in life, and don't idle away his life until he dies (the film takes death as the observation point).
