Huainan beef soup shops are many, and the production process is many, and the scale is very small. In the local area, everyone calls it beef soup, without the word "Huainan". In other cities, the signboard of Huainan Beef Soup appears, just like Lanzhou Lamian Noodles, which is called "Beef Noodles" by Lanzhou people. In some other places, it is called "authentic Lanzhou Lamian Noodles". To beef soup and beef noodles is another example; Nouns such as steamed stuffed bun and fried dough sticks are impossible to register trademarks. To register a trademark, the brand name must be added, and the brand has value only if it is recognized by the people. The beef soup in Huainan is very cheap, and now it is only 4 yuan a bowl, so the trademark is meaningless to the beef soup in Huainan.
