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.

By sticking to my principles and what I firmly believe in - I always have my own attitude towards everything in life. I wish to create trends rather than follow them. My daily routine at the moment is really just a combination of work and family.

To me, my nephew is the angel of my world. It is my absolute happiest moment whenever he smiles at me.

We do have responsibilities, as we live on this planet. It is our one and only home, which we are obligated to protect, to keep as beautiful and harmonious as it is. It is really for everyone to do so, including you and me.

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!

I love raising awareness and encouraging people to take action for World Environment Day, because it demonstrates how individual voices can become a global chorus for change.

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!"
