    In ancient times, people celebrated Qing Ming Jie with dancing, singing, picnics, and kite flying. Colored boiled eggs would be broken to symbolize the opening of life. In the capital, the Emperor would plant trees on the palace grounds to celebrate the renewing nature of spring. In the villages, young men and women would court each other. 
    Celebrated two weeks after the vernal equinox, Tomb Sweeping Day is one of the few traditional Chinese holidays that follows the solar calendar-- typically falling on April 4, 5, or 6. Its Chinese name "Qing Ming" literally means "Clear Brightness," hinting at its importance as a celebration of Spring. Similar to the spring festivals of other cultures, Tomb Sweeping Day celebrates the rebirth of nature, while marking the beginning of the planting season and other outdoor activities.
