Hi everyone, I am Li Na, the world No 5 tennis player from China. I am really glad to be back in Beijing to meet all my "Na Ions" (nickname of Li's fans) after traveling around the world this season. A whole week's stay in my hometown of Wuhan after the US Open refreshed me from the fatigue of playing in North America, where I reached the semis of the US Open in New York for the first time in my career. I also visited Madame Tussaud's in Wuhan to check out another "me" made of wax, which was a pretty cool experience.

However, the fun times always pass too quickly and I resumed training with my coach, Carlos Rodriguez, at his tennis academy, the Potter's Wheel club, in Beijing last week. His tough training regime, which features equal time on fitness and technique, is always challenging but all the sweat and pain have paid off as my fine-tuned serve and improved volleying has helped me to be more aggressive on court.

It wasn't easy to change the playing style that I've persisted with for more than 20 years. But when you get used to the adjustments and the effects start to show, you are like, "Oh, this is my tennis".
