The Spring Festival is the most important of the traditional Chinese festivals. It is often (call) "Lunar New Year", because — as part of the lunisolar (阴阳的) Chinese calendar — the date is partially determined based on lunar phase (月亮或行星的相位). The festival traditionally (begin) on the first day of the first month in the Chinese calendar and ends with the Lantern Festival is on the 15th day. Chinese New Year's Eve, a day when Chinese families gather for their annual reunion dinner, is known as Chú Xī. It literally means "Year-pass Eve".
According to (tale) and legends, the beginning of Chinese New Year started with the fight against mythical (神话的) beast called Nian (年兽). Nian would come on the first day of New Year to devour livestock (牲畜), crops, and even villagers, (especial) children. To protect , the villagers would put food in front of their doors at the beginning of every year. It was believed that after the Nian (eat) the food they prepared, it wouldn't attack people any more. One time, people saw that the Nian was scared away by a little child wearing red. The villagers then understood that the Nian was afraid the colour red. Hence, every time when the New Year was about to come, the villagers would hang red lanterns and red spring scrolls on windows and doors. People also used fireworks (frighten) away the Nian. From then on, Nian never came to the village again.
