What does this sign language mean?

That's Chinese sign language "I love you",

Once a boy in the Chinese department lost his favorite because of this sign language. When girls express their love in sign language, boys misunderstand it as "I'm sorry", so after the movie, boys don't go to girls. Many years later, when he used this sign language to tell his boss that he was sorry, the boss said strangely, "This is the sign language of the Chinese Department. How do you know? It's just that you used it in the wrong place. It stands for' I love you'". At this time, the boy suddenly realized, but it was too late.

The last sign language of Chinese department!
