Wei Wuxian laughs because ice skating is still terribly new to him. Somehow people must enjoy seeing him awkwardly try to balance on thin pieces of metal. "I won't say that I like it, but I have been learning. I know how to move forward and not fall down."

That really is an accomplishment considering how things started. Of course he can still count how many times he has been on skates on one hand. He really has the frozen world they were able to go to to thank for even bothering with such a thing.
