People dine in Lao Sze Chuan Chicago Downtown restaurant in Chicago, the United States, on July 26, 2020. "Most of our restaurants closed door and stopped takeaway service, out of concern for the safety of the staff," Hu said. "But lots of our old clients, frontline workers in particular, hope we can provide service." Thinking twice, Lao Sze Chuan in Chicago persisted. And the Chinese restaurant has gone beyond that, it started to offer free lunches and dinners to frontline workers. (Xinhua/Xu Jing)
