Tomb-sweeping Day, also known as pure brightness day, is one of the most important traditional festivals in China, which usually falls onto 4th, 5th or 6th of April. On the tomb-sweeping day, people will visit their ancestors' graves and mourn for the dead, burning incense, offering food and paper coins. They will also clean the grave area, such as getting rid of weeds growing around the tomb and removing dust on the tomb-grave. After that, some flowers would also be presented. People usually refresh earth, sacrifice and show flows to their ancestor's on this special day.
During the days around Qingming, everything is recovered and refreshed, so many outdoor activities like traveling around, flying kites and planting trees are favored by many people.
