Which of all Roland’s ghost movies are about a group of people traveling in life?

You may be talking about "Yin Qi", but it is not a trip. It is two actors renting a house. The son played by the landlord Roland died and was left as a body in the house. In the room, the ghost of his fourth son would go there at night. Later, he met a heroine, but her aunt came, so she had sex with the girl next to her.
