Can you guess what happened and why the girl is in the tree? As you can see, she is young and beautifully dressed. It's not common to see a girl climb a big tree in so fashionable clothes. Yes, something unusual must have happened. 

The reason is that the police was coming and she had to run and avoid being captured. When she was cornered and had nowhere to hide, she quickly climbed up the tree nearby. Why did she have to run away when the police came? Nobody would do that if they've done nothing wrong or illegal. Yes, you guessed it. The truth is that she was a street walker, who makes a living by standing on the street to attract male customers. 

If you think that the story ends when it comes to this point, I'm sorry to tell you that you're not a person with great imagination. Have  you ever wondered how a girl could possibly climb a tree so high so quickly? She seemed to be a nimble climber and her arms appeared very strong. You have to be very imaginative to truly understand things In China. Sometimes you need to practice thinking out of the box. Got it? Yeah, "She" is in disguise and is male, actually. You can always make money if you're creative enough. And the story I just told you is just an example.
