Joker Xue and Zhu Xingdong sang Jiangnan in the variety show "Hey! Sing." Joker Xue and Zhu Xingdong sing Jiangnan in the eleventh episode. In the 11th issue of Sing Up, Joker Xue and Zhu Xingdong sang a duet of JJ Lin's "Jiangnan". However, there were some minor problems at that time. One was that the program team deliberately lowered the volume of Zhu Xingdong's microphone, and the other was that some people on the Internet suspected that Zhu Xingdong was lip-synching. So Joker Xue used the method of exchanging microphones to help Zhu Xingdong prove himself.
