I am a guy living in Shenzhen. I am now married, but before I got married I had some fun. If you are thinking about a boob job, then it may be hit or miss. That I know of, I have encountered three women that have had the job done. One was perfect (perfect prefect). One was very good. Both look and feel.
The third was pretty good on sight but definitely looked a little unnatural, not horrible, just prototypically boobjob-like. However, it felt like a bag of vacuum-packed beans inside--in that the sac would move, but with quite a bit more effort and felt a little squared off.
I should stop talking now.
But I won't. I am thinking about lasik surgery, but won't have it done here in Shenzhen. Part of the reason is I worry about it not being done right--even though a Shenzhen doctor with lots of experience may be just as good, I like have the threat of a big lawsuit hanging over my doctor. Part of the reason is that I want to be able to fully communicate with the doctor. Not taking chances with my eyes.
The closest my wife has had to plastic surgery here is eyeliner tattoo, which worked out very well for her.
