As Arlington High School students enter a classroom hung with red-and-gold masks and a wall-length watercolor dragon, Xu Qiang greets them, “Ni hao.”
“Ni hao,” each responds, guessing the meaning: “Hello.”
Later, Xu locks himself out of the classroom and tells the laughing student who lets him in, “Xie xie.” He repeats the performance for one boy who doesn’t get it.
“Thank you,” the boy says, scribbling. He corrects himself: “Xie xie.”
In another lesson, Xu asks the class, “Tung xuemen hao?” (Students, good?). They answer, “Lao shi hao.” (Teacher, good.) Then Xu has them switch roles.
“You are my teachers, too,” Xu explains.
