Japanese / Chinese poetry question
Lately, I’ve been reading an old text in Japanese. It's an autobiographical account, written by a Japanese male who was educated in the late Edo period. At one point in the text, the man includes something he wrote that he calls “a Chinese-style” poem. The writer gives only the opening several lines of the poem, which he says he composed in his youth and has largely forgotten. He adds that his family was very poor, so the theme of his poem was 二十四貧 (twenty-four aspects of poverty). So, presumably there were 24 lines in total to this poem, with each line ending in 貧 (poverty).
Below are the first three lines. (The original was written vertically; here it is horizontal, left to right):
貧士処貧不辞貧
三尺炉辺守清貧
負米自比子路貧
My questions:
First, I wonder....is 7 characters per line x 24 lines a prescribed form of classical Chinese poetry, and, if so, is there a name for such a 24-line style?
Also, what about the way the writer ends each line with the same word? Is this also a prescribed form with a name?
I want to find out more, but I haven't been able to find anything similar to this poem. None of my Japanese colleagues here can help me out, and I don't know Chinese. I’d appreciate any information.
