How are you?

Today, was listening to music using my 酷狗 , when I scroll down the playlist,

suddenly my eyes stop on this --- [你最珍贵] ...Memories flashed back..

I got a friend, who also like this song, he once said,

my smile is the most valuable thing..

Well, we doesn't contact each other for some time already..

Just wanna know, How Are You? I hope you are doing fine there..
