What is the meaning of the poem entitled the people of tao-chou?

I could not find that specific poem, but read severl others on the website humanistictexts.org and the following description of the man and his motives:

Po Chü-i (772-846 CE), a poet and a government official, was one of the great writers of the Chinese Tang dynasty. He was born at T'ai-yuan in Shansi, settling later at Ch'ang-an near the north-west frontier. The held the post of palace librarian and several provincial governorships. He was banished a number of times for arguing against government policies. In 832 he retired to the Hsiang-shan monastery a few miles from Lo-yang, the eastern capital. As one of his poems explains, he suffered from paralysis at the end of his life, one leg becoming useless.

In much of his poetry, Po Chü-i appears easy-going. But he had a caustic view government's effects on the lives of ordinary people and used satire and humor to draw attention to the rapacity of minor officials, to social problems, and to questionable religious practices. In an early protest he wrote a long memorandum criticizing the prolonging of a war against an unimportant frontier tribe. In his lighter poems he mused on events in his daily life, his own experiences, and aspects of himself.
