Best answer: Spring Festival is commonly known as Chinese New Year. According to legend, a young man named Wan Nian saw that the festival was in a mess at that time, and he had a plan to fix it. One day, the movement of the tree shadow inspired him, and he found that every 360 days, the four seasons cycle once. Wan explained to the monarch the principle of the movement of the sun and the moon, and the monarch left it, hoping to measure the laws of the sun and the moon and create a calendar. After the establishment of the calendar, pray for the monarch to set a festival for thousands of years. Zu Yi said, “Spring is the beginning of the year, so let’s call it Spring Festival”.
Spring Festival is also called lunar calendar, commonly known as “Chinese New Year”. According to legend, in ancient times, a young man named Wan Nian saw that the seasons were chaotic at that time, and he had a plan to fix them. However, he couldn’t find a way to calculate the time. One day, he was tired of cutting wood up the mountain, and sat under the shade of a tree to rest. The movement of the tree shadow inspired him. He designed an instrument to measure the time of day by measuring the sun shadow. Later, the dripping spring on the cliff inspired him, and he made a five-story leaky kettle to calculate the time. Over time, he found that every 360 days, the four seasons cycle once, and the length of days is repeated. At that time, the monarch was Zu Yi, and he was often upset by the unexpected weather. Years later, he took the sundial and clepsydra to the monarch and explained to Zu Yi the principle of the sun and moon running. Zu B was greatly pleased and felt reasonable. So, the ten thousand years were left behind, and the Sun Moon Pavilion was built in front of the Temple of Heaven, and the sundial platform and leaky cauldron pavilion were built. It is hoped that the laws of the sun and the moon can be measured accurately, the exact morning and evening time can be calculated, and a calendar can be created to benefit the people of Li people all over the world. After the establishment of the calendar, Wan Nian pointed to the astronomical phenomena and said to Zu Yi, “Now it is exactly twelve months, the old year is over, and the Spring Festival begins again. Please ask the monarch to set a festival.”. Zu Yi said, “Spring is the beginning of the year, so let’s call it Spring Festival”. It is said that this is the origin of Spring Festival.
