Sekihan

Red bean rice, called patbap in Korean, sekihan (赤飯) in Japanese, and hóngdòu fàn (红豆饭) in Chinese, is an East Asian rice dish consisting of rice cooked with red beans. Hóngdòu fàn (红豆饭) is a traditional Chinese dish found in some regions of China. It is particularly common in Jiangsu province and eaten during the Winter Clothes Day. A legend from the Dafeng area of Yancheng, Jiangsu says that people eat a bowl of glutinous rice mixed with red beans on the Winter Clothes Day in Jiangsu to commemorate a shepherd boy who was slain by a landlord. It is said that a long time ago, an adorable shepherd boy was born into a poor family. His parents could not support him, so he made a living by shepherding for a landlord. One day, his carelessness in tending to the sheep resulted in those sheep falling into a valley and dying. After hearing the news, the landlord was extremely angry. Consequently, he beat and scolded the shepherd boy. The shepherd boy begged for the landlord to stop the relentless beating but he did not. When the shepherd boy believed that he would die from the beatings, he fought against the landlord, but the landlord picked up a knife next to him and killed the boy. The blood of the shepherd boy stained the glutinous rice on the ground red. Coincidentally, that day was 1 October.
