Parents see piano as a key to unlock success By Zhao Xinying | China Daily | Updated: 2021-02-10 10:19 Share CLOSE A competitor performs at an international piano competition for teenagers in Guangzhou, Guangdong province. CHEN JIMIN/CHINA NEWS SERVICE Many believe children's intellectual abilities can be boosted by learning the instrument. Zhao Xinying reports. Guo Yujing hasn't touched her piano for two years. That would have been unimaginable when she was learning to play the instrument from the ages of 5 to 15. At that time, Guo practiced for at least two hours a day. When an exam drew near, she spent all day－with the exceptions of mealtimes and sleeping－studying the black-and-white keys.
