During this period, the weather turns warmer and sometimes drizzly, and all of the plants start germinating. The Qingming observance originated way back in ancient China. Chinese people use this traditional holiday to give thanks to their ancestors, to cherish the memory of departed relatives, to cultivate filial piety, and to reconnect with family members.Besides demonstrating respect to their ancestors, people also take this opportunity to travel together and go on long walks in parks and in the outskirts of the city. Children play together and use willow branches to make things. They pick wild flowers, and are free to play as much as they want. So there's another nickname for Qingming Festival, "Taqing", which literally means: to walk on the green grass.
