Many believe that life has smiled on Yang Mi: at the age of 4, she got her first TV drama(剧)role; at 16, she became a model for a fashion magazine; at 18, she went to her dream college — Beijing Film Academy (学院).   

Last year, the 24-year-old actress played bad girl Luo Qingchuan in the time-traveling TV drama, Palace. The drama became a big success and made Yang very famous. The number of her micro blog followers soared from several thousand to more than 3 million overnight.

Could she be any luckier? Yang doesn’t think luck had anything to do with her success. She paved her way all by herself. “Every chance comes from the efforts I’ve made,” said Yang. People now think she’s very hard-working.      

She doesn’t forget the time when people gave her the cold shoulder. Some treated her with little respect. They didn’t want to help her in her time of need. “I have to thank them because they gave me the drive to prove myself,” she said. That’s why she is eager to help others when they are in need.

In May, Yang became the ambassador (大使) for the Climate Group. She calls on people to join the Million-Miracle (百万奇迹) project and plant trees on China’s dry land. Together we’ll fight the bad weather!
