When was The River of Dodo Amsterdam written?

The river in Amsterdam is written in 1989. I went abroad to Holland this year and lived in China for 15 years. This poem can be said to be a homesick poem, which can be compared with Yu Guangzhong's Homesickness. Of course, the effect may be interesting.

Toto once said, I basically mean nervous. I don't read poems without tension, or poems without tension, which is meaningless. In The River in Amsterdam, Duo Duo presents an image in an instant, breaking the limitation of time and space. Truth is an illusion and history is present, which forms the tension between time and space and creates a free-flowing tension effect. Of course, the display of this skill is based on the poet's strong homesickness. Dodo once came back and asked his friend which river in Amsterdam this poem was about. He said that there are many rivers in Amsterdam, and none of them belong to me-there is no river here.
