1) There is a manufacturer's logo near Zheng's head in front. Obviously, the fake Dunhuang looks a little dim.

2) The real Dunhuang Guzheng has a laser anti-counterfeiting label on the lid of the Zheng, which is specially customized from Hong Kong. In order to prevent counterfeiting, the laser anti-counterfeiting label mold has been destroyed.

3) The real Dunhuang Guzheng has a quality inspection strip on the back of the Zheng near the tail of the Zheng, with the signature of the quality inspector on it. Fakes are basically stamped, even if there is a label, it is wrong.

4) The information and bar code of the real Dunhuang Guzheng are hung on the sound outlet on the back. We can call the manufacturer. If it is true, we will tell you the model, name and corresponding dealer of this Zheng. Barcodes can only be queried once. In order to prevent counterfeit merchants from buying only a real Dunhuang ancient town, barcodes are constantly used.
