What is the style of Feng Zhi's poems?

Although Feng Zhi's poems are also free poems, many of them are quite neat. In Song of Yesterday, there are many poems with four sentences as a paragraph, each poem has three or four more steps, and each pair rhymes. Later, in the 1940s, he published sonnets. This kind of western metrical poem was once translated into "Shanglai Style" by the poets of Crescent Society, and many people learned to write it. Therefore, Feng Zhi began to write free poems and turned to pursue metrical poems.
