As far as the current situation is concerned, if you just use the four words "Shaxian Snacks", it will not constitute infringement; but if you imitate others in terms of graphics, logos, store decoration, etc., it may constitute infringement. .

First of all, even if the graphic of "Shaxian Snacks" is a famous trademark in Fujian Province, it does not change the fact that these four words have not been successfully registered.

Secondly, “Shaxian Snacks”, as a geographical indication, has no right to prohibit others from using it normally. As long as you can prove that you are not making false propaganda or misleading consumers, you can use the words "Shaxian Snacks". It does not necessarily need to be authorized by an association. (The words "Shaxian Snack Industry Association" are collective trademarks. Only those who join the collective have the right to use them. There is no other way and no one can be authorized to use them.)

Again, you can Fair use is made through the business name on the business license, that is to say, the name on the license is "**** Shaxian Snack Bar".
