Unfortunately, Chinese companies do not normally go by their English names.  By law, only their Chinese business name matters, they can (and often do) use any English name that they wish as long as it doesn't cross obvious trademark boundaries.

I know nothing about them personally but it appears that there is plenty of information in the public domain about them. A search engine is your friend for that one!

this is their website , if any one can give some info about them
