"I did not expect to break the national record, I just concentrated on the race. I was happy to be the only swimmer set a new national record in the six-day competition. It is not easy to swim a good result here since it is 800m plateau. I felt difficult to breath in the longer distance than 50 meters," Yan said.

"No one could compete from 100,200, 400, 800, 1500 freestyle in one meet. I did it! Especially I did it with the reaction of plateau, such as dryness, sore throat and fatigue. I felt proud of myself," Sun said with tears.
"It was a challenge and test for me that I finally overcame all those difficulties and all five races. It also brought me more confidence in the future. I will take good rest and set my next goal in the Asian Games in August," Sun said.
