Learn how to dance to Super Junior's Sorry Sorry Sorry and Crayon Pop's Bar Bar Bar and she'll be all yours.
I'll let you in on a secret, Korean chicks think Chinese dudes are macho by default. Just don't act like Captain Korea and you'll be fine.

Also don't act like a b1tch... if you are from anywhere outside Guangdong, you should be ok.
As a Western guy to a Chinese guy, heres a few mistakes we notice you guys making:
Cut and file your finger nails down.
Don't spit, clean your ears or blow snot rockets in her presence.
Don't carry her purse around
Don't carry a 'man' bag around, it looks gay.
Don't be super friendly and follow her relentlessly
Don't stare at your phone
Don't buy her gifts or take her to expensive restaurants (lanzhou noodles are just fine)
