Yonex badminton rackets are divided into CH version and JP version according to different sales areas. At present, only the CH version supports after-sales in Chinese mainland. As for the version of VT-ZF2 mentioned by the questioner, it should refer to different star versions produced by Unix, including Dānlín's version of VT-ZF2LD, Li Zongwei's version of VT-ZF2LCW and Unix's released version of VT-ZF2, and the signed version of VT-ZF2LD released by Dānlín, the four great kings, last year.
The performance of these rackets is the same, the only difference is whether the rackets are painted or not.
