Zhang Yunlei and Guo Qilin have a very good relationship. The two are not only colleagues in Deyun Society, but also uncle-nephew.

Zhang Yunlei followed Guo Degang since he was a child, and naturally grew up with Guo Qilin. When he was a child, Guo Qilin lived with Zhang Yunlei. Guo Qilin was thirsty at night and did not dare to pour water by himself (it is said that Guo Qilin has been timid since he was a child). When he was young, he always slept with his brothers), so he asked Zhang Yunlei to sleep with him. Zhang Yunlei fell asleep and said in Tianjin dialect, "This has been like this since I was a child. What will I do when I grow up?" ? Later, after Zhang Yunlei’s Nanjing incident, Guo Qilin went to see Zhang Yunlei. Zhang Yunlei asked him to pour water for him to drink. Guo Qilin sent back to Zhang Yunlei what Zhang Yunlei said to him at that time. This does not mean that Guo Qilin holds a grudge, but that Zhang Yunlei has a bright future. When he's hopeless, give him some fun.

According to Zhang Yunlei when he was in the small theater, he said that Guo Qilin once called him and called him "uncle". Zhang Yunlei instantly knew that Guo Qilin wanted to see him for something, because Guo Qilin would only call him if something happened. Uncle, as expected, Guo Qilin asked Zhang Yunlei to wash his underwear. Although Zhang Yunlei later washed Guo Qilin's underwear, the process was also very fun. Would you like to wash someone else's underwear if you don't have a good relationship? Like would you wash your friend's underwear now? The answer is no, which shows that the relationship between the two is extraordinary.

At Zhang Yunlei's special event, someone mentioned Guo Qilin, and Yang Jiulang said, "I know, that little fat guy". Zhang Yunlei immediately replied, "Don't say that to him, how cute he is." That is to say, I can hurt him, but others can't. From this, we can also see that the relationship between Zhang Yunlei and Guo Qilin is extraordinary.

At Deyun Society’s Wire Festival, when the boxes were still being sealed, Guo Qilin and Zhang Yunlei sang a tender version of “Exploring Qingshui River + Zhaohuatai”, and their collaboration could be described as a fight between gods. Adapting a Beijing ditty into a gentle version without departing from tradition can be said to innovate traditional culture. The trio of Zhang Yunlei, Guo Qilin and Meng Hetang often appear at Deyun Society's large parties, which actually shows that the three have a good relationship.
