Every room under the roof of the Jing family is full of weird things: the old grandmother Wei Junyi (Cao Cuifen) who appears to be a Buddhist but has a clear inner mirror, the power-hungry and ruthless aunt Luo Zhusi (He Saifei), the pretentious and spoiled eldest sister Jing Zhenzhu (Lisa Chui), the vain and pretentious maid Lu Jiao'e (Wang)Xin Ting (played by Xin Ting), the dandy and domineering younger brother Luo Aji (played by Liu Xiaobei), and the obedient and sleek son-in-law Lin Donglin (played by Wang Shanshui). Faced with all kinds of difficulties, Ai Sixi and Jingkan tried their best.
