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

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.

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.

Environment protection weighs the same in my life as my professional acting career.

Air pollution is my biggest concern right now. Maybe because I live in Beijing, and in this city we have such severe challenges due to bad air quality. It has affected our daily lives and health. I do not go outdoors because of it. I desperately hope that we can improve the current situation.

I always have my own attitude towards everything in life.

I only started to understand the concept of "environmental protection" 14 years ago. I was an ambassador for a charity event, and the staff told me that the consumption of disposable chopsticks in China, per year, could result in the devastation of unimaginable acres of forest.
