Qing Ming or Thanksgiving?
Qingming is popularly associated with Jie Zidui in the Spring and Autumn Period, who saved his starving lord's life by serving meat cut from his own leg. The lord, known as Jinwengong, was later able to take power and decided to reward Jie but he declined. Jinwengong tried to force Jie out of a forest by fire but instead burned him to death and felt deep regret. He ordered all his people to ban the use of fire and eat cold food that day to mark Jie's death. It is the origin of the Cold Food Festival, which starts one or 2 days before Qing Ming and later merges with Qingming. Qingming Festival then became an important holiday from an originally simple farming day.
