Spring Festival is the most important of the traditional Chinese holidays. It is often inaccurately (call) “Lunar New Year”, because—as part of the lunisolar Chinese calendar (农历)-the date is partially determined based on lunar phase (月相). The festival traditionally (begin) on the first day of the first month in the Chinese calendar and ends with 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 beast (神兽) called Nien (年). Nien 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 Nien (eat) the food they prepared, it wouldn't attack any more people. One time, people saw that the Nien was scared away by a little child wearing red. The villagers then understood that the Nien 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 Nien. From then on, Nien never came to the village again.
