I have bought MD702 all system in China. But it is in english language. I would like to have it change to Chinese Traditional languge. How can I do that ?

I have contact the shop and they said this version is sell for English language !

My serial number is MDE315000052

 I have got a request from support that my MD702 cannot be change. Only Autel selling out of China can be change. Is that the official answer  that I expect to get from support ?
