Lyric discussion by cascade107 

Well, it's Sunday, May 7, 2017 - I've been waiting five years to comment on this post.

The song is about a girl that he's in love with but the girl is closed off to him (but not necessarily to others). She has some dark things in her history that I feel she wants to open up about, but can't - possibly to protect someone else that she loved in the past and can't let go of.

The name "China" and the Great Wall around her heart is a bit of a stretch. But who knows what the song writer had in mind.

There. I feel much better now after keeping this bottled up for the past five years.

@cascade107 why wait five years??
