Old Master Tan is the patriarch of the Tan family, mentioned as calling Tan Ci from the Old Residence to remind him to return for dinner because a girl from a family friend is visiting. He appears to be concerned about Tan Ci's family and social obligations, likely wanting to arrange a marriage or family connection. He is authoritative, expecting Tan Ci to attend family dinners despite his busy schedule. He is somewhat traditional, maintaining family ties and relationships. He is mentioned only in passing through Tan Ci's phone calls and conversations, but his influence is felt in the expectations placed on Tan Ci. He is presumably elderly and concerned with the continuation of the family legacy. He is not personally present in the narrative but is referenced as part of Tan Ci's background and familial obligations.
