There is a misunderstanding that Xu Huiting, played by Zhang Yue, is Li Tang's lover, mainly because Ding Meixi, played by Tan Zhuo, once said that Li Tang still has money for the little lover, and this "little lover" refers to Xiao Ting. But don't forget that this "little lover" may also refer to a daughter.
Of course, the most important thing in the end is age. In Opponent, Xiao Ting is going to graduate school, which means that she is 23 or 24 years old, while Guo Jingfei plays Li Tang. When Lao Wei goes to investigate the sales records of pharmacies, she sees the information of Li Tang. Her ID number is 1978, which means that Li Tang is 43 years old now.
Xiao Ting is the child of Li Tang's first girlfriend, but not necessarily the daughter of Li Tang. Before her death, her first love girlfriend entrusted Xiao Ting to Li Tang. Because of a promise, Li Tang has been sending money to Xiao Ting for school in Xiao Ting for so many years.

Lin Biao, played by Li Ning in Opponent, knew that Xiao Ting was coming to study here earlier than Li Tang and Ding Meixi, and Li Tang was called by Xiao Ting to know that Xiao Ting was coming to study. It can be seen that Lin Biao's every move in Li Tang was monitored by Li Tang and relevant personnel.
At the same time, this Xiao Ting may also be a spy. As a new group of spies, like Ding Meixi and others in Li Tang 18 years ago, they were sent here to lurk. Therefore, Lin knew he would come here to study. Anyway, Xiao Ting will be online, and the plot will definitely be better.
