homesickness

Yu Guangzhong

Homesickness is a small stamp when I was a child. I'm here and my mother is there.

When I grow up, homesickness is a narrow ticket. I'm here and the bride is there.

Later, homesickness was a low grave. I'm outside and my mother is inside.

Homesickness is a shallow strait now, and I am on this continent, on that side.

This is Yu Guangzhong's homesickness.
