The high level of English is a standard for a top student.
1. What do you think about TV commercials?
I hate them. They are a nuisance in China. The commercials give out false and misleading information. They also break down the flow of the show. Sometimes, they last too long in China. We have a joke about it. We would say, it’s not commercials in between episodes of TV series. It is TV series in between commercials. I know the TV stations profit from broadcasting TV commercials. I also know without commercials our favorite shows will all be canceled. But I still think there are just simply too many commercials and the stations can afford to cut some of them.
2. Never use your eyes to cry for the wrong person who hurt you. Instead use it to search for the right one.
3. Do not repay anyone evil for evil. Be careful to do what is right in the eyes of everyone.
4. You have to believe in yourself, That's the secret of success.
5. Action is the key to all success. Should you have any dream, you must go out and fight for it.
