Yes Liu Hongyun is a barefoot doctor in the countryside. He bought medicine from the town for villagers who were inconvenient to get in and out of the town. Although he has to earn a lot of difference, it is cheaper than going to town to buy flowers on the road. A few years later, he learned acupuncture to collect money to treat villagers, but he had no foundation, which led to his reputation being damaged. He was arrested by the police in April 2022 because he didn't have a drug sales license to sell drugs.
