What traditional cultures are described in Cold Food and Looking at the Moon at Fifteen Nights?

Cold Food Festival: It is a traditional festival in ancient China. This was handed down in the Spring and Autumn Period. Two days before Tomb-Sweeping Day, it was decided by Jin Wengong to commemorate the meson push who burned to death with firewood. On this festival, it is forbidden to make a fire and only eat cold food. In the development of later generations, the customs of sweeping, climbing, swinging, cuju, hooking and cockfighting gradually increased. The Cold Food Festival, which lasted for more than 2,000 years, was once known as the largest folk festival in China, and it was the only festival named after the food custom among the traditional festivals in China. The climate in early spring is dry, not only the kindling preserved by people is easy to cause fires, but also the occurrence of spring thunder is easy to cause mountain fires. In this season, the ancients held a grand sacrificial ceremony to put out all the kindling handed down from the previous year, that is, "forbidding fire", and then drilled a new fire as the starting point of production and life in the new year, which was called "changing fire" or "inviting new fire". When the fire is changed, a grand ritual activity is held to burn the symbol of millet, the god of cereal, which is called human sacrifice. After the custom was passed down, it formed the later No Fire Festival. In this period when there is no fire, people must prepare enough cooked food and live on cold food. This is the so-called "cold food", hence the name "Cold Food Festival".

Mid-Autumn Festival: It began in the early years of the Tang Dynasty and prevailed in the Song Dynasty. In the Ming and Qing Dynasties, it has become one of the traditional festivals in China. Mid-Autumn Festival has the custom of enjoying the moon, eating moon cakes, enjoying osmanthus and drinking osmanthus wine since ancient times. The Mid-Autumn Festival is a colorful and precious cultural heritage. The full moon is a symbol of people's reunion, a sustenance for missing their hometown and relatives, and hopes for a bumper harvest and happiness.
