Please use English to write comments! thanks!!!

I would greatly appreciate it if comments made to my blog were ONLY in English, as I sure can't read Chinese!

I was also told by a friend that some of the comments in Chinese were rude. :(

I do not know what to do? Should I just delete ALL that are not in English, as I can't moderate them???

I plan to ask my Chinese friend to tell me which ones I should delete, but she works and does not have much time. : /

Any other suggestions? Thanks.
