ORIGIN:
        In 600 B.C. in Shanxi province, lived a man by the name of Jie Zi Dui.  He saved his lord's life by serving him with a piece of flesh from his own leg.  Later the lord became the ruler of a small principality, he invited Jie to follow him.  However, Jie declined, preferring to lead a seculded life with his mother in the mountains.
        The lord thought that maybe by burning the mountain could force Jie out.  Hence he ordered his men to set fire.  To his consternation, Jie remained there and was burnt to death.  To commemorate Jie, the lord ordered all fires to be put out on Jie's death anniversary.  Therfore began the "cold food feast" because no food could be cook since no fire could be lit.
        The "cold food" festival takes place on the eve of Qing Ming and is considered part of the festival.  However, Singaporeans do not practice putting out the fire.
