Who are the most famous poets of landscape poetry in the Northern and Southern Dynasties?

The most famous poets are Xie Lingyun (385 ~ 433) and Xie Yuezhao (464 ~ 499), who are called "big and small thanks" in the world. Daxie is good at changing scenery and painting. Occasionally, I can write such a natural and ingenious stroke as "Spring grass grows in the pool and willow turns into songbirds" ("Going upstairs in the pool"). Xie Yuezhao's landscape poem "Self-citation, Solitary Flow, Beautiful Scenery, Enjoy" (Selected Poems of Caijitang) is a great thank you. As its famous saying goes, "Yu Xia is scattered into Qi, and Chengjiang is as quiet as practice. Noisy birds cover Chunzhou, and miscellaneous English is full of Fangdian "("Going to Sanshan Night "); "Knowing the boat of heaven, distinguishing the river tree of clouds" (Xuancheng) has reached a high level in capturing the interest of mountains and rivers and in the coexistence of scenes.
