The middle-aged man standing next to Chen Xuan was a distant relative of the Ji family in Jincheng named Tian Bing. It was Tian Bing who was responsible for receiving Ji Wushuang during her visit to Jincheng.
Ji Wushuang called him Uncle Tian. After performing divination for Chen Xuan, she brought him to meet Tian Bing and asked him to arrange a job for Chen Xuan at Jincheng University.
Because Ji Wushuang did not disclose any of Chen Xuan's background information, nor did she act as if she held him in particularly high regard, Tian Bing could only assume that Chen Xuan was a destitute friend of hers—and not a very close one at that.
