Phoenix Flower Blooms Again has been sung by both Chen Chusheng and Shuimu Nianhua. Most of the songs I can find are by Chen Chusheng, but I personally think the song sung by Shuimu Nianhua (Miao Jie) gives people a warmer feeling.

The Sound Of Silence, the theme song of the film The Graduate is also good.

What is still fresh in my memory is that I wish you a safe journey. The parting time was the most tearful.
