"Staying true to yourself is very important for songwriters," he says.
Apart from Sun and Mao Buyi, A-list actress Song Dandan, singer-songwriter Hua Chenyu, pop star Meng Meiqi and the show's co-initiator Long Danni also coach the female contestants.
They have been divided into two groups-the "start" and "restart". The former involves contestants who haven't been onstage before. The latter? Well, they have been there before and are seeking a new beginning.
Singaporean twins Miko and Yumi Bai, from the "restart "group, broke into entertainment circles in 2008 when they were only 16 and enjoyed huge popularity in Asia.
However, after going through some ups and downs, they have remained on the sidelines in recent years.
The show presented the twins with a perfect opportunity to relaunch their stalled careers.
In the first episode of the show, their performance wowed the other contestants and won approval from the coaches.
"All they need is a chance to display their talents," says Long.
"We would like to help both the newcomers and restarters who have a passion for music and a strong thirst for a bigger stage to realize their dreams."
