How to talk to a girl you like when you meet her in the playground?

It seems that you are young and shy, and you need a simple explanation to tell you a more suitable method of chatting up shy boys. For example, if you see a girl in an amusement park, you stare at her and think she is leaving, and ask her how to get to the exit. He told you that you would turn around at the next intersection and ask her 2 3 times, and she was not far from the exit. It should be said that after taking you out of the park, you will say that you thank her more and invite him to eat KFC or something. If not, if you go, you have to call someone and ask her out another day. This is because you are shy and won't appear abrupt at first. Secondly, if the girl will know that you are interested in her (if she is not stupid), I am specific enough. There are many ways to divide it equally.
