Feng Feng, a community worker, took the responsibility of buying essential medicine for those with chronic diseases in Huiminyuan community in Wuhan's Jiang'an district starting from February. The photo has gone viral online.

Feng used to help record information about the novel coronavirus pneumonia, but he also got assigned a different task-buying and delivering drugs for patients with chronic diseases in his community.

"Most of the patients are elderly, and the drugs most in demand are those for treating diabetes and hypertension," Feng said.

"Sometimes I work more than 12 hours a day and have to go to more than 10 drugstores to get the needed drugs, but I still cannot buy all the drugs for them," he said.

Although many patients in the community asked him to buy a two-month supply of drugs at a time, Feng said that during each shopping trip he could only buy enough to last one month. Otherwise, he would not be able to carry them back to the community.
