What I want to say is ``As long as you look for the trademark of "Xu Fu Ji", it can be said that 99% of them are genuine. Generally speaking, the main fakes are that the packaging style is similar, but the name is the same as that of Xu Fu Ji There is definitely a difference. In addition, be sure to check whether there is a graphic trademark on the outer packaging. If it is not something like "Hu Fu Ji", "Zhang Fu Ji"... and the like, but there is a graphic trademark, it is the real thing! If the price difference is too high compared to the market price, you should be more careful and see if the production date is approaching. Also, has the product form changed? Generally speaking, the authentic Xu Fuji Candy and Pastry Farmers Market is 3.00 yuan/500 grams cheaper than in large supermarkets. It is possible.
