Liu Dazhao is Liu Yinyin's older sister-in-law, married to one of Liu Yinyin's brothers in the Liu family. She comes out of the kitchen holding a bucket of pig feed to feed the pigs that the Liu family had raised that spring, with the two piglets now being almost four months old. She greets Liu Yinyin warmly as she returns from catching fish. The narrative notes that thanks to Liu Yinyin recently bringing back food for the family a few times, the family has been eating much better than before, highlighting Liu Yinyin's contributions to the household. She is addressed as Big sister-in-law in the conversation and represents the extended family living together.
