What kind of poem is y chibi fu, which shows the poet's feelings?

When Su Shi was in Huangzhou, his thoughts were contradictory: on the one hand, he felt sad about the cruel blow; On the other hand, I always want to seek liberation from Laozi and Zhuangzi Buddhism. On the one hand, he shows broad-minded and adaptable personality, on the other hand, he is closer to reality. His "Red Cliff Fu" reflects the thoughts and feelings at this time.
