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

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.

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.

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

I saw a dead elephant in one of Kenya's natural reserves. Around her were footprints of her baby elephant. This was just so sad, as three days before, perhaps the mother was still taking the baby around to play and to drink water. In her mind, she probably was thinking they had a life of decades to be together. However, the poaching happened so fast and everything collapsed. Without the protection of the mother, the baby elephant is likely to die too. That moment changed me.

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

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.
