Su Baili's biological father. He has a leg condition that requires him to use a cane for walking, though he deliberately avoids using it in front of Su Baili to save face. He works hard and the family's financial situation is not great due to medical expenses. He is proud but humble, and deeply cares about his daughter's impression of the family. He mentions that his tastes are similar to Su Baili's, particularly regarding sweet and sour spare ribs.
