What are the poems praising Genghis Khan and Genghis Khan himself?

Genghis Khan himself did not write poems. He only knows Mongolian, but he can't read. I wonder if he ever sang. There are countless poems and songs related to Genghis Khan. China, Mongolia, Central Asia, Persia and Russia all have a large number of poems and folk songs related to Genghis Khan. Most people who praised him were Mongolians and their descendants.
