It would be best to have pictures, but according to your description, they should be: Yong, Jia, Si, Ling
In the poetry world of the Southern Song Dynasty, Xu Zhao (alias Linghui) and Xu Ji (named Lingyuan), Wengjuan (named Lingshu) and Zhao Shixiu (named Lingxiu), collectively known as the "Four Spirits of Yongjia". Among them, Weng Juan is from Yueqing County, Wenzhou, and the other three are from Yongjia County, Wenzhou. Wenzhou was called Yongjia County in ancient times, and Yongjia County was the prefecture of Wenzhou in the Song Dynasty. The four poets all had the word "ling" in their names. They had similar interests, consistent creative ideas, similar poetic styles, and formed a school of their own. They were therefore known as the "Yongjia Four Spirits". .
