The Grandma Everyone Kneels To

Jennie has lived alone in the mountain forest for years, long enough that the family she left behind has no idea what she used to be, and a police officer has to talk her into going down to see her great-grandson. What she walks in on is a custody fight. Her great-grandson and his ex-wife are at war over their daughter, and the reason he wants the girl is that a rich man's son will pay three million for her. When Jennie objects he shoves her and insults her. His ex-wife takes her for a senile relative and decides to look after her. The two of them end up selling snacks from a stall, and that is where the girl, who has run away from her father, finds them. The great-grandson and his girlfriend come after her, and Jennie puts both of them on the ground with one strike. Back at the old family house he turns up again with the buyer in tow. The buyer's father recognises Jennie, drops to his knees, calls her his teacher, cuts off a finger by way of apology and throws his son out. Jennie then takes charge of the girl's education. She goes to Qingbei University to find her a teacher, points out a professor's mistake, and the academician and the president who hurry over dismiss him on the spot and bow to her. Later the town's power brokers hold a banquet and lean on the ex-wife to hand over a secret recipe. Jennie shows up, and the next day the same men are on their knees asking her to head the chamber of commerce.
