Under the stimulus of developing commercial economy and overseas trade, the social customs characterized by prevailing luxury and extravagance was gradually formed in Fujian Province from the mid-Ming Dynasty on. The transformation started from the material culture and later spread to people’s mental attitudes including the public ethics and human relations. Compared with what happened in the Jiangnan area (the Yangtze River Delta), the change in Fujian Province was less profound and thorough, but it highly surpassed the North China society, where many sub-prefectures and counties remained unchanged till the end of the Ming Dynasty. However, there were also some coastal or interior regions in Fujian which continuously maintained a simple and unspoiled social atmosphere for the unbalanced economic development.
