Zhou, doctor of piano.

I found three songs with pictures and truth (click on the pictures to enlarge).

Dream and Princess Pearl are the second songs sung by Wei Zi. The ending song of the second part of the Taiwanese version of Princess Zhu Huan is an episode of the imported version of Chinese mainland.

Vietnamese song Con Bm Xuan (Butterfly in Spring)-Hi? n Th？ C (Shu Hua)

Vietnamese version of "Love Your Good Girl" (it must be Vietnamese version, because the rhythm is very different from Chinese version)
