David Emanuel Ávila Alfaro, right, teaches kung fu to Mario Amaro, 12, left, and Leonardo Amaro, 9, center, in Mexico City. The class was suspended for more than 15 months during the pandemic and resumed with a requirement to wear face masks indoors. “There haven’t been many problems with giving classes,” Ávila says. “But the students are wearing face masks, and sometimes I demand a lot of effort from them, a lot of endurance.”
