First of all, to answer your second question, those places are famous because they must have the habit of eating ducks, such as Beijing, Tianjin, Shanghai, Hangzhou and other southern regions. Because of different eating habits, the types and ways of eating ducks are different in different regions. Guangzhou people want to eat duck slices, but don't like meat very much, so they prefer the southern way of eating. In their eyes, the duck roasted by King Duck is more delicious and famous than that of Quanjude. (Although Quanjude also has two kinds of meat slices and duck with meat) Shanghainese like to eat lean ducks, unlike the stuffed ducks in Beijing and Tianjin, most of them are duck with meat, so Shanghai is also dominated by Duck King and Yanyunlou. Duck meat is very popular in this cuisine, and local consciousness exists, so it is famous. Because of historical accumulation and long-term habits, Quanjude is more famous for its region and diet.

So the first question is also reflected in the second question I answered. No more answers! With the gradual strengthening of national health care awareness, the advantages of duck meat are gradually loved by the public. It is expected that in the near future, more new brands and regions will appear one after another, which is also an inevitable trend.
