Find an old movie. This is a ghost film. I think it was taken in Hong Kong. It's about a female ghost who lives in a dry well without water and comes out of a bronze mirror.

The Ghost in the Ancient Mirror starring Brigitte Lin.

Ghost in the Ancient Mirror describes a scholar, Chen Zhonggong (played by Shih Chun), who is filial to his mother and finds a quiet and dilapidated old house and lives in it. He bathed and fasted every day, copied a scroll of Buddhist scriptures for 100 times, helped his mother "make a wish" to the Buddha, and made a merit at the same time. Who knows, there is an ancient well in the ancient house, which often drowns people. The iron-toothed scholar does not believe in evil and denounces it as superstition and nonsense. So, a young female ghost, played by Brigitte Lin, emerged from the bottom of the well and was named "Susu" ... Isn't this the story of Zhenzi? At first, she pretended to serve her son's daily life and copy books. In fact, she wanted to replace the big boss behind her, and the demon dragon came to harm people. However, the son who copied the scriptures was really healthy and protective, but in the end, he saved Mr. Zhou from the clutches of the dragon-he tied the well with a rope and took out an ancient mirror from the mud at the bottom of the well, which freed Mr. Zhou from the control of the monster. It turns out that mr.zhou is not a ghost, but the incarnation of a mirror. In order to repay his son's kindness, mr.zhou decided to commit himself to serving his son all his life. However, just as they were relaxing their trip, although they copied the Buddhist scriptures 99 times, they only missed one time, allowing the demon dragon to take advantage of it and break up the ghost love that could have been happy, which ended in tragedy.
