Sun Daba is the son of Sun Laoxi (also referred to as Old West Sun and Uncle Sun Dalei from the west side). He is described as very tall, over 1.9 meters, even taller than Geng Feng. He is skinny like a bamboo pole, with long arms and legs, thick eyebrows, big eyes, thin lips, and a rather handsome face. He dressed in coarse blue clothes and looked quite decent. Suqin described him as tall, hardworking, articulate, capable, and a pretty decent young man. He came for a matchmaking meeting with Tang Xiaomei. He was the only son with no older or younger sisters.
