I used to think hard work made me come alive, honestly. I used to have a daily work schedule with millions of things on it and I thought, "This is wonderful!"

Take charity work for example; the motivation of my various charitable activities is neither for fame nor profits. It is my sincere wish that, through my efforts, more people can realize how important it is to protect our planet and to start to act for a change.

It may surprise people to learn that one elephant is killed every 15 minutes for its ivory.

I cannot imagine my hometown without forests, and I cannot imagine the earth turned into a desert.

Perseverance is my biggest lesson. When I started to get involved in environmental protection some years ago, my people did not take it seriously and they never considered it important. But today, people look at what I do and they truly recognize those efforts, and eventually they join you as "environmental activists" too!

All I want to say is that life is very fragile. We should live every moment and cherish what we have been given.

As the Ambassador for WWF Earth Hour, I still vividly remember that there were only 80 buildings in China that participated the Earth Hour in its first year. Six years later, there were 170 cities and thousands of buildings that participated. We are still growing strong. I am encouraged by the accomplishments we have made together and they make me proud and more determined than ever.
