In the world badminton championship, three chinese boys entered the first fourth

In the world badminton championship matches, three chinese boys entered the first fourth, and they also defeated the No.1 seed athlete, which ensures China can get the championship at last!
Last night, I watched the matches between Chunlai Bao and Chongwei Li, as well as between Hong Chen and Gade of Denmark, though it was very late, I felt very excited for each excellent attack!
Badminton is one of my few favorite sports, in the past year, I kept the habit of playing badminton each Sunday afternoon!
In my opinion, if one wants to play badminton with a high level, he should own below skills:
1 Deep base knowledge and training of badminton;
2 Quick reaction;
3 Active: being active, you can always be at the correct position which is beneficial to both attack and protect!
Expectation: in the future, I still have free time to play badminton.
