How about Yanxitang in Weihai?

The drug price of Yanxitang is alarmingly higher than before. The main reason is that it can't afford it. I wanted to monopolize the market for a few years at first, but I couldn't monopolize it later. It is too expensive to recover capital now. If I want to go on, I can only raise the price. Slowly, people realized this and began to decline.
