Qingdao Children's Palace. Yu Fuer, head of the Little Haiyan Children's Dance Troupe of Qingdao Children's Palace, in March 2022, an epidemic broke out in Qingdao, which made the teacher and her 32 children pause in the weekly public dance class. Online classes have been suspended, but the children's daily online practice has not stopped. From the news, we can see that all Qingdao people are making their own contributions to the silence of their city in different ways. Teacher Yu hopes to lead the children of the Art Troupe to dance together, give play to the appeal of literature and art, convey their own strength, and praise the heroes who fought in the front line of fighting against the epidemic together. So teacher Yu Fuer teaches dance in Qingdao Children's Palace.
