Tomb-Sweeping Festival, a day to pay homage to ancestors.
On Qiao Family's side, Qiao Qinghe and Sun Family are still in good health, but on Zhuang Lühe's maternal side, both of her parents are deceased, leaving only a stepmother and a half-brother, who is also Qiao Xiaomai's uncle.
Neither family interacts much outside of holidays, but with the approach of Tomb-Sweeping Festival and according to Zhuang Lühe's past routine, she would always return to her maternal home to pay respects to her biological parents.
But now that she has run off and Qiao Changshun's leg is crippled, Qiao Xiaomai has decided not to return to her grandmother's home this Tomb-Sweeping Festival.
Her step-grandmother, just like the Sun Family, is one of a kind too. Though her cheap uncle is pretty decent, it's better to keep Zhuang Lühe's disappearance a secret for as long as they can.
