So, sites like cherry blossoms have few Chinese girls, there are some on the big sites like match.com but I don't really like those big dating sites due to their horrible business practices, and there are some sites geared towards western/Chinese relationships where the girls often seemed to be putting on a bit of a show.
I've found that on plentyoffish.com there are a lot of Chinese girls. I guess compared to the size of the country it's not much, but still plenty for a guy to contact. If I narrow down the search to what I'm looking for (23-27yo, doesn't smoke, no kids, not married, speaks English, college degree, can't remember what else) I get hundreds of results, the first 100 or so of which have been online within the last week. Technically it's a good site as well. All in all, it's a great way to meet Chinese girls and free. The local selection sucks but that's life. All the Chinese girls I messaged responded, though I'm sure there are some on the site who don't want to relocate. Some will put down that they are just looking for friends but few seem to mean that.
I never really liked any of the other sites for meeting Chinese girls but this seems like a great option. No I am not a paid advertiser.
