Note NNN needs to be in Chinese (if you include any other languages you need that officially translated and notarized).
It needs to be notarized in the city/province of the vendor properly stamped and signed by the other party.
You don’t have to be personally there but you need to be represented ~ it can be personal to you or your company!
Hope this is helpful!
Dumb question why don’t you give them x y z use these improvements to capture more new subscribers ~ then raise the prices because you have x y z!
Seems like a no brainer!
