Also called Jin, the younger twin brother, seven years old. Born to a maid in the Pei household, making him a marginal figure. Naturally intelligent with an exceptional memory but lacks guidance. In the original story, he was placed in a remote corner at the Secretary's study and performed poorly, but with his wise mother's help and Sister Lian's assistance, he later studied at the Xu household, passed six successive exams, and ultimately achieved first place in the highest civil service exam. He became quiet and reserved due to his struggles.
