The first time I heard Juan's original "Angel's Wings", there were also many cover versions of Xidan Girl, Xu Yuteng and other groups and singers on the Internet.
Christine also has a song of the same name, Angel's Wings.
Liu Shanshan also has a song of the same name.
Pan Er also has a song of the same name
Zheng Zhongji also has a song of the same name.
But I don't know which angel wing the landlord is talking about, but I have collected these hopes to help you.
