Shen Mu is Shen Wu's mother. She is a middle-aged woman who treats her son Shen Jizu better than her daughter Shen Wu. She is more concerned with Shen Wu's usefulness as a daughter-in-law than with her happiness. She is described as training Shen Wu to be good at work and do things. She is somewhat embarrassed when Shen Wu exposes her attempt to take the fried dough sticks and peach cakes. She curses in her heart that girls are more attached to their husbands. She depends on her son-in-law Lu Xuan and smiles to keep harmony.
