Yep. Plenty said on this elsewhere....
CELTA and Trinity are highly regarded and of some value, but are quite expensive and only worthwhile if you're going to make a career of this.
Otherwise, you generally don't really need any kind of certificate. A college degree is the requirement; if you have one you're going to find work in China. If you don't have one, you're probably not going to be legally employable as an English teacher...and a cert likely won't make any difference. A degree is enough.
If you feel really nervous about being a teacher, take a real-time hands-on certificate course...doesn't matter where. But do this for YOU...not to impress an employer.
IMHO an online cert, from ANYWHERE, is virtually worthless...doesn't help you OR impress an employer. Might tip the scales a bit if you have an employment challenge, such as being non-Caucasian (sorry) or not from a Big Six country (USA, Canada, UK, Ireland, Australia, New Zealand).
Otherwise...don't waste your time or money.
