This is a movie "Charming House", which tells that Zheng Yuling and Dong Chengyi are a cohabiting couple who are about to get married, but for some reason, their original new house can't be occupied, so they rent their good friend Zheng Danrui's grandfather's old big house. Nina Li Chi and Tang Liqiu are the black market wives and maids of Zheng Danrui's grandfather Lu Haipeng. After they died, their ghost stayed in the big house and waited for Lu's return. When people live with ghosts, a series of jokes will happen.
