It is a clas­sic Chi­nese song sung by Tere­sa Teng. The lyrics just re­minds me the gen­tle­ness of Clay. Here are the lyrics in En­glish:

On some day, some month in some year
Feels like a bro­ken face
It's so hard to say good­bye
Just let ev­ery­thing go far away
This is not an easy mat­ter
How­ev­er, we did not cry
Let it come sub­tly
Let it go qui­et­ly
Years af­ter years
I can't stop miss­ing you, miss­ing the past
Wish the wind would blow again from the sea
Just for touch­ing the hand of the wave
Just like your gen­tle­ness (more)
