1. Be yourself 做你自己
It's important to maintain self confidence by being yourself around girls. If you adopt an alternate personality to attract girls, you will eventually be weighed down with the feeling that your true self isn't good enough. It may help to develop and improve your social skills, but any girls that don't appreciate you for who you are don't deserve your attention。
2. Be a gentleman 做一个绅士
Girls love guys that are polite and courteous. It's just a matter of doing simple things like holding doors open for them and being respectful in other ways. Some claim chivalry is dead, but if you believe that, then you're going to have some problems getting a girl's interest.
3. Make eye contact 眉目传情
Many girls like it when you can't take your eyes off them, but not when you're staring at their boobs. Although there are some girls that may enjoy such attention, you won't offend anyone by focusing on her face instead. Do not ogle her. Just remember to use discretion and show proper respect.
4. Make her laugh 逗她开心
Being funny is one of the most attractive qualities a guy can have, and if you're not "handsome", a girl will usually overlook that! If you're not goofy but you have a very dry, sarcastic sense of humor, use that. Just watch your timing and try not to be too goofy, or you may make a fool of yourself. It's okay to tease her a little, but generally not about her appearance.
5. Notice when you're having a conversation and she seems uncomfortable, change the subject.
Watch her movements, if she's shifting her weight a lot and not making eye contact, chances are she's uncomfortable。
6. Recognize that physical contact should be limited by the state of your relationship.
Acquaintances--A handshake when introducing yourself is probably a reasonable limit for a first meeting. You can also subtly brush your hand against her hand or arm.
Good Friends--It is generally acceptable to give friendly hugs to girls that you know fairly well, even if you aren't a couple. Just be sensitive to the girl's feelings about it; pressuring her to hug you will make her uncomfortable.
Don't focus too much on one girl if she isn't enjoying the extra attention. She may get annoyed, and it will likely hurt your relationship. 如果女生不想你们之间发生额外的关系，那么不要对她表现出特别的关注。一旦激怒了她，那么很可能会损害你们现有的关系。
Get to know her friends and be friends with them. This will show her that you're nice and friendly.
Don't ever tell her that she looks bad. 永远别说她看起来很糟。
