Kindergartens usually won't take kids younger than 18 months, but try looking for something called "tuoersuo" 托儿所 or seeing if your kindergarten has a "tuoer ban," 托儿班. This is basically the same thing as daycare. It won't be academic at all, they'll keep your child fed and entertained, but that's about it.
Personally, I think daycare/kindy can be great (both my kids are in kindy now) but you need to be really really careful about where you put your child. Traditional style Chinese kindergartens/daycares can be sort of scary. My son has a classmate, for instance, who left his old kindy and came to ours after his parents found out the old kindy had been closing kids up in the bathroom with the lights off as punishment. Some kindergarten teachers will hit the kids, and even if they don't hit, the teachers can be pretty rough -- arm dragging, yanking the kids around, that sort of thing. Early childhood education doesn't even require a high school diploma in China, it is a certification you can get after middle school, in a trade type school, and so the quality of the teachers varies a lot. There are good schools -- I'm really happy with my kids' school, but anything that is more modern or progressive is not going to come cheap (my son's kindy runs from 4000rmb-9000rmb a month, depending on the program you choose).
I think with that young of a baby I'd get an ayi before going for daycare in China. It won't cost you *that* much more and you can monitor the ayi much more easily than you can the daycare.
