Ruì'ān
Rui'an lies on the Feiyun River in southern Zhejiang. Its scholars helped shape the Yongjia school of thought, known for studying institutions and practical affairs as well as the Confucian classics. Chen Fuliang and Ye Shi, both associated with Rui'an, became leading figures of the school in the Southern Song. Their concern with government and livelihood gave the learning of the Wenzhou region a distinctive voice in the intellectual debates of their day.
