The authenticity of Guanghe fermented bean curd can be identified at the moment of opening the lid. If the lid of sufu is easy to unscrew, it may be a fake product produced by a small workshop or a black market processing factory, because they are not produced according to the regular formula, and the taste may never catch up with the sufu produced by a genuine manufacturer. Therefore, to judge whether Guanghe sufu is genuine or not, just feel it at the moment of opening the lid.

Sufu is a delicious food, but when you buy it, you must distinguish the regular brands and manufacturers to avoid eating counterfeit products with poor quality.
