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

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.

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 wish to create trends rather than follow them.

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.

To me, my nephew is the angel of my world. It is my absolute happiest moment whenever he smiles at me. I have stopped working 24 hours a day like I was before, and I rush back home to see him whenever I can after work. That always makes my day.

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.
