In China, there is an interesting phenomenon: there are pharmacies on every street and alley, more than vegetable vendors and supermarkets. For example: if you feel indigestion or discomfort and go to buy medicine, the clerk will almost always first recommend traditional Chinese medicine. If you decline, they will recommend patent Chinese medicine. If you still refuse, they will suggest the most expensive Western medicine. If you say you want Famotidine (a Western medicine name), their face immediately darkens, hesitating, then they go to a hidden corner to take out that medicine, and when you see the price, it's only 5 yuan.
