I can't understand Daniel Wu's The Demon Night Cloister. Can someone explain what this is all about?

The whole film "Demon Night Cloister" tells a nightmare, and the fragments are fragmented, because the protagonist's dream is fragmented. The whole dream mainly tells the dilemma and contradiction that Yuan Sen, the hero, wants to get rid of the past but can't get rid of.

Introduction-

Yuan Sen (Daniel Wu) is a famous British photographer, but the day before the photo exhibition, he received a phone call from his mother (Kara Wai) telling him that his twin brother had died unexpectedly. ? When Yuan Sen returned to Hong Kong, he found his mother remarried and his stepfather was a black fireman. Moreover, he also met President Chen (Kaohsiung), who was once strict with himself. ?

My brother's cause of death is unknown, leaving only a banned book that is difficult to read. My mother began to believe in Christ, but she still couldn't overcome her demons. Yuan Sen found out the fact that his mother had molested his brother in the past. ? Yuan Sen met his classmate Shi (played by), who is now a famous radio program host. ?

Yuan Sen got a call from the librarian and learned that his brother had borrowed some books and forgot to return them. So he went to the library and found that his brother had been using his ID card. When Yuan Sen was looking up information in the library, he accidentally learned from old newspapers that his brother was killed by a group of monkeys, but the name of the deceased written in the newspaper turned out to be "Yuan Sen"

He is an old man, representing Yuan Sen's own demons (hatred). Yuan Sen hated the headmaster and Shi, who had hurt him in the past, and wished they all died. Under the arrangement of the old man in the library step by step, they all died. Xiubing is a beautiful coat worn by demons. When the demon came to him, Yuan Sen didn't see clearly that it was his own demon. The ghost king gave Yuan Sen the power of revenge, that is, a gun. Yuan Sen killed the stone with it, but it also made him realize the true nature of the devil.

The demons drove him crazy and killed the headmaster. After Yuan Sen woke up, he wanted to get rid of demons, but he was firmly controlled by demons. He couldn't let go of the beautiful coat of the demon (Xiubing), so the old man said that it was useless for Yuan Sen to have a passport now. The children of Yuansen and Xiubing represent the darkest side of human nature, which is what the devil finally wants.

Yuan Sen finally found that the root of his pain and contradiction was not the unbearable past and the harm of others, but his demons and hatred for the past, which made him unable to let go of the past. In the end, Yuan Sen woke up in this nightmare, reviewed all his nightmares and found that fortunately everything was just a dream. (end of the play)
