Detective Galileo Episode 6 Method of Solving Cases

Li Mei is not her father's own daughter now, but her mother's illegitimate daughter, and she is also a painter who died in a car accident before. (That's the painter Xiao Xun and Xiao Ba used to visit together when they were children. )

In fact, the car accident that caused the painter's death was not accidental, but arranged by Li Mei's mother (who had an affair).
