The three-year-old son of Ruan Youjin and the little darling of the Ruan family. Despite his young age, he has a sweet tongue and constantly calls out 'grandma' and 'uncle', making Ruan Xiulian and Song Tingzhu proud. His face was often smudged like a kitten while being cared for. He is one of the children Song Tingzhu plans to teach to read and write along with Jinning, Xiaomei, and Xia Ge'er. Wu Erniu wiped his face while noting that girls and young boys in the village rarely knew how to read.
