In 2004, due to the copyright issue of the new album songs, the bamboo tree culture was in trouble, and Xie Xiaodong chose to temporarily withdraw from the music scene. Since 2005, he has been focusing on the operation of China Baby Special Fund and other public welfare undertakings, striving to build China Baby Music Classroom and Hope Primary School in poverty-stricken areas.

In August 2007, Xie Xiaodong, who had been away from music for three years, signed a contract with orange sky entertainment's Orange Tianhua Music Record Company to return to music. In the long-awaited expectation of fans, he released his fifth solo album-2CD "Curtain", which was immediately praised by fans and the market.

Singing is their favorite occupation, and they will not give up easily.
