Select method 1. It depends on the place of origin: if you buy China Rana chensinensis, you should recognize that it is produced by Rana chensinensis in Northeast China. Because there is no standard for wood frogs in China for the time being, some unscrupulous businessmen will argue that wood frogs can also be called China wood frogs. ? 2. It depends on the peeling method: it depends on whether the China Rana chensinensis is peeled dry or wet, that is, whether it is hung dry or raw.

The latter is not inferior, the price will be cheaper than dry skin, but the water content is as high as 20%~50%, and the medicinal value will be slightly lower than dry skin. ? 3. Look at the appearance: The more beautiful the China Rana chensinensis, the higher the foaming rate, and the foaming rate of different qualities of China Rana chensinensis varies greatly. The foaming rate of the bad China Rana chensinensis may be only one beat and five beats.

I have been eating China Rana for several years. I remember that when I just bought China Rana, I was often cheated (mainly because there were too many fakes), and later I chose the brand directly. I'm eating Bao Zhong China wood frog now. As an industry representative, I have been interviewed by major media before, and I am still at ease.
