When I was a child, homesickness was a small stamp.
I'm at this end,
Mom is over there.
When I grow up, homesickness is a narrow ticket.
I'm at this end,
The bride is over there.
Later, homesickness became a temporary grave.
I'm outside,
Mom's inside.
Now, homesickness is a shallow strait.
I'm at this end,
The mainland is over there
