After 20 12 was introduced to China, Wan Wen vendors made use of "information asymmetry" to keep the name and origin of the decorated nuts strictly confidential, fabricated information such as scarce yield, and made malicious speculation and profiteering.

In the second half of 20 15, with the origin of commodities being mastered by more and more people and introduced into China, the price of framed bracelets dropped significantly.

On March 20 16, the name and place of origin of box nuts were disclosed in detail in Baidu Encyclopedia, which was widely forwarded by previously deceived players and domestic wanwen lovers.

Later, in order to protect their improper interests, domestic vendors tampered with Baidu Encyclopedia, tampered with the names of tree species in the place of origin, adhered to the relationship with "Indian white sandalwood", tampered with the output, distribution, artificial planting, and tampered with nut size data, hoping to continue to create speculation hotspots through these tricks and save the domestic price of "frame nuts" from falling sharply after the information was disclosed.
