青衫素衣
[qīng shān sù yī]
Translates as 'Blue Shirt Plain Clothes'. In ancient Chinese culture, ‘青衫’ (qing shan), typically blue or green attire, symbolizes scholars or people of scholarly inclination. Meanwhile, plain clothing referred to here as ‘素衣’ (su yi) traditionally indicates humility and austerity, which combined together project an image of someone cultured yet simple living life modestly.
