Text:
When I was a child, homesickness was a thin popsicle.
I'm at this end and grandpa is at that end.
When I grow up, homesickness is a short WeChat.
I'm here and my mother is there.
Later, homesickness was a narrow moon.
I'm in charge, grandma is in charge.
Now, homesickness is a thin photo.
I'm outside and my hometown is inside.
