Historical documents from the Eastern Jin Dynasty (AD 371-420) mention the festival, while records from the Tang Dynasty (618-907) depict the grand evening banquet of Emperor Taizong and his concubines. By the Song (960-1279) and Yuan (1279-1368) dynasties, special articles for the Qi Xi were seen being sold on markets in the capital.
