“The people are the heroes now.” So sang Mao’s military as our 37th U.S. president touched down aboard Air Force One at the top of Nixon in China, touching off the phenomenon that came to be known as “CNN Opera.” The vogue is back with the Hubei Opera’s epic new The Angel’s Diary, hot off the newswires. The angels in question are Wuhan’s heroic medical personnel, striving mightily to contain the coronavirus. But in the end, China is still China, so it’s “the people [who] usher in the city’s ‘reboot,’” as a teaser instructs us. “They reunite again in a lush spring, basking in the brilliant sunshine.” —M.G.
