Ning wants to see the wedding photos of Ruan Liuzheng and Ning Zhiqian, thinking she is his mother. When Ning Xiang met Ruan Liuzheng for the first time, he thought she looked familiar, and later asked her if she had been to Africa, and Ruan Liuzheng had just been there. Ning wanted to call her mother right away, which made Ruan Liuzheng very flustered. Ning Zhiqian never told Ning Xiang his real life experience, Ning Xiang asked him where his mother had gone, and he said he went to Africa to perfunctory her. Ning wanted to meet Ruan Liuzheng, but found that she was the one in Ning Zhiqian's wedding photo, and mistaken her for his mother.

In order to prove his statement, Ning wanted to find the wedding photos of Ning Zhiqian and Ruan Liuzheng. Although the two have been divorced for many years, Ning Zhiqian has always kept their wedding photos, but put them in a more conspicuous place, so Ning Zhiqian can only see them. When Ning Zhiqian saw that Ning wanted to take out the photo, he was very angry, lost his temper at him, and put the photo back in the highest cabinet. Ning Zhiqian's reaction was a bit like getting angry because his mind was exposed.
