I'm wondering where can I buy the power converter and adapter plugs??

Christy, they can be found at local electronic products markets. I am afraid that you may not know where the markets are. You may visit the supermarkets and see if you can find some there. I saw converters and adapters in the supermarkets.

OK Thanks David I appreciate it! I'll prob just buy them from here and then take them to China instead of trying to find them there.

If you are still looking for convertors (absolutely essential), any good online travel supply company has them, such as TravelSmith, Magellan's, etc, or you can get them thru Amazon. Be sure you have convertors not only for your destination country but also any country where you might have a stopover.
