Poetry that deals with wanting to be rescued?
There are few examples I can think of that exactly match your request of wanting (the poet himself) to be rescued. I think the reason here is the Chinese culture, in which people usually express their personal hopes in a more euphemistic way.

Here I think of a few related example that may be closest to your need:


《茅屋为秋风所破歌》 by 杜甫. In the poem, he described his poor status and he want to rescue all the poors in the world -- this kind of universal love makes it a well-known poem. The most famous segments:


  安得广厦千万间，大庇天下寒士俱欢颜，风雨不动安如山。

《虞美人》 by 李煜, who is the last emperor of the Nan Tang dynasty. He wrote a lot of sad poems since his country is going to fall. His sadness mixed with his hope of returning to the old days.


  小楼昨夜又东风，故国不堪回首月明中。

《满江红》 by 岳飞. The poem express the feeling of the General Yue Fei, who wants to save his country (Nan Song) from being defeated by alien empire Jin.


  靖康耻，犹未雪。臣子恨，何时灭。驾长车，踏破贺兰山缺。
