Lan Bo, director of the documentary film "Wuhan, I Am Here," stands in a screening room before a viewing of his movie in Beijing, Saturday, Jan. 15, 2022. The homeless, the sick, the elderly: For people who fell through the cracks of the official system, the then-unprecedented decision to isolate the central Chinese city of Wuhan and its 13 million people was a matter of life or death. Director Lan Bo hopes to sound the alarm with a documentary about volunteers who helped neighbors get food and medical care following the lockdown in early 2020 of the city where the coronavirus pandemic began.
