It's the first day of the lantern festival, which means people eat rice balls to celebrate family reunion. According to legend, a court official named Dong fang Shuo fell for a palace maid, but she couldn't make it to her family because she wanted to help the girl realize her love for the emperor. Dong Fang Shuo thought that if the emperor allowed people outside the city to light up the city, the whole city could come together and celebrate the festival. This would make the festival a big success.
