Dong Fangshuo met a maid-in-waiting in the palace and prepared to jump into the well and commit suicide. When she asked, she learned that the maid-in-waiting was named Yuanxiao. Because she hadn't seen her family in the palace for a long time, she had the idea of suicide. Dong Fangshuo made a plan to help her. Make people rumor that "the fire burned me on the sixteenth day of the first month." People in Chang 'an panicked, and Emperor Wu of Han asked Dong Fangshuo for advice. He replied: "Chang 'an is robbing, burning the Forbidden City for fifteen days, and having a red midnight snack. "It means: On the fifteenth night of the first month, people hang red lanterns in every household outside the city and set off fireworks in the city, just like setting a fire in the city to deceive the Jade Emperor. That night, Yuanxiao's parents went to the city to see the lights. With the help of Dong Fangshuo, the family was finally reunited.
It's just folklore. It really tells us that Dong Fangshuo is very smart, the motherland has a long history and profound cultural heritage, and the people in the community are very intelligent.
