What are the poems about Hong Kong, Macao, Taiwan and Motherland?

There are too many, and this one should have the deepest impact on me:

Nostalgia

When I was a child

Nostalgia is a small stamp

I am on this side

My mother is on that side

When I grow up

Nostalgia is a narrow ticket

I am here

The bride is there

Later

Nostalgia is a short grave

My mother is inside

And now

Nostalgia is a shallow strait

I am here

The mainland is over there
