Em... This question is kind of interesting. In fact, the skills of picking up girls are similar, and will not be essentially different because of which industry the girl is in. Only, in the process of chatting, if you can use the knowledge of the girl's industry to bring each other closer, so that the girl can have more to talk about, it's still quite good:

Opening: Hey, wait a minute, I only have a minute, if I don't say hello to you to get acquainted with you, I may feel regret later, because there are a lot of pretty girls in Beijing, and I think you are especially friendly.

Suitable scenarios: non-social occasions, moving targets

Evaluation: "Hey, wait a minute" stops the target first, "only a minute" is false time, "afraid of regrets " gives her a very valid reason, and "there are a lot of pretty girls in Beijing, and you're friendly" is conditioning.
