Su Zhichen is Su Yue's eldest brother, mentioned as one of the brothers who send goods and money to their sister. He is part of the family network that supports Su Yue's independence and status in the county. His contributions are significant enough that Wu Xiulian fears losing access to them if she antagonizes Su Yue. Su Zhichen is not directly present in the narrative but is referenced as a key figure in the family's economic and social connections.
