I. Precautions for Dunhuang Guzheng:
1, the signature on the certificate is handwritten or stamped, but please note that the guzheng instructed by Teacher Li Sufang is handwritten. Before February 20 18, Miss Li used a black carbon pen, and then a blue ballpoint pen. Other teachers are supervised by stamping and handwriting, and the delivery batches in the factory are different.
2. The flying fairy of the Dunhuang logo on the side plate is not necessarily clear. This flying fairy is carved by the machine abrasive of the manufacturer, and generally it will not be reprocessed. Some of them will have a somewhat vague pattern.
3. Dunhuang guzheng does not necessarily have the word Dunhuang engraved on its code. The word "Dunhuang" is not engraved on the low-end Zheng code. For example, 696D and 694KK are not engraved, and 695/698 series and above products are engraved with Zheng code, such as 698T calligraphy peony, 698JM dream flower and 5698JT lady.
4. The sole of guzheng code does not necessarily have anti-slip grooves. At present, the 696 series Dunhuang guzheng is basically non-slip, and the 694 series and above are all non-slip.
5. The logo label of Dunhuang on the panel is concave and convex, not completely flat.
6. Dunhuang guzheng is not all signed, and what is not signed is not necessarily a fake. When Zheng's father Xu was alive, only some models were signed by Zheng's father. After Zheng's father died on April 9, 2009, there was no piano sign. It is not excluded that some merchants hoard secondhand goods and sign for them.
