What kind of company is Deshantang in Henan? Have you ever done it there?

When I just graduated, I stayed in this company for 2 days. Under the guise of organizing free travel for the elderly, the elderly are tricked into registering personal information with the company. When registering information, people in the company will ask you if you have chest tightness and other symptoms, and then sell health care products with false propaganda to the elderly.
