I found this poem entitled Flower (花) by Taiwanese poet Bi Guo (碧果) on the MRT:

花

僅差一步

就是

 

界

外

脫去衣裳可以走了

 

Flower

Just one more step

Is

 

The

Beyond

One can leave after shedding one’s garb

I also liked the stylized way the author’s name was written on the poster.

Bi Guo was born in 1932 and is the author of several poetry collections, including A Heartbeat Afternoon, A Changing and Unchanging Canary, Corporeal Awareness and Poetry Belongs to Eve. He has also published a collection of essays, a novel and a play. You can hear him reading some of his poems in Chinese below in a video by the Culture Bureau of the Taipei City Government:
