Wang Cuifen's second son. Similar to his brother Da Bao, he has a sturdy, round head with a vacant, dull expression. He sniffles and wipes yellow snot with his crusted sleeves. He is also greedy for the thermos and wool coat. Wang Cuifen mentions saving the money for Da Bao to use for a wife later, and Li Jiao threatens that Da Bao and Er Bao won't be able to hold their heads up again if she exposes the family.
