Tell me a joke about a foreigner and a China.

Once, a very rich foreigner went to China and started a company with a monthly salary of 1000 USD. A China native (who can speak English) saw it and went back to learn English at once. One night, he learned four words: 1. Yes! 2. Don't! 3. Thank you! 4. Goodbye!

The next day, people from China came to our company and achieved success.

After a month, everyone left after work in the afternoon, and China people were still sweeping the floor. Seeing that he was still sweeping the floor, the boss asked, "Did you sweep it yourself?" "Yes!"

"Really?" "Yes!" "This is a tip of 100 yuan for you." "Thank you!"

The next day, China people were sweeping the floor again, and the boss ran over and said, "Are you sweeping the floor again?" "Yes!" The boss added, "Have you seen my gold watch and my silver watch?" "Yes!" "Then give it back to me!" "no!" "If you don't give it back to me, I will call the police!" "Thank you!"

"You want to go to prison for five years! Five years! " "oh! Goodbye! " Foreigners fainted on the spot! ! !
