Self-made yellow calendar

According to legend, a long time ago, there was a young man named "Wannian" who made a living by firewood. He is very clever. Seeing that the festivals at that time were chaotic, he was determined to correct them, but he didn't know where to start.

One day, he went up the mountain to cut wood, and when he was resting, he remembered this festival again. He thought hard and stared at the shadows. Suddenly, he was inspired by the moving shadow. When he got home, he designed a sundial instrument to measure the length of a day. However, what should we do when the weather is cloudy, cloudy, foggy and rainy? Later, when he was firewood on the mountain, he went to the spring to drink water, and saw the spring dripping rhythmically on the cliff, which aroused his interest. He looked at the dripping spring with ecstasy. After returning home, he began to make five-layer leaky pots. Time is measured by water leakage. In this way, he slowly discovered that by measuring the shadow of the sun and recording the time of water leakage, the length of the weather would repeat every 360 days. The solstice in winter is the shortest day.

Due to the disorder of festivals, agricultural production has been affected, and people complain a lot. The son of heaven Zuyi is also very worried. He telephoned the officials to find out the cause of the holiday chaos. A Heng, a festival official, said that people have offended God. If you want a normal holiday, you must worship the gods and ask for forgiveness. The son of heaven believed it, led hundreds of officials to worship the gods in the Temple of Heaven, and called the people of the whole country to set up a platform for worshipping heaven.

Ten thousand years thought that sacrifice was futile. He went to see the son of heaven with a self-made sundial instrument and a water leakage device, and explained the reasons for the disorder caused by inaccurate festivals. According to the results of my own determination for many years, I explained the winter solstice and the cycle of the sun and the moon. After hearing this, the son of heaven felt that Wan Nian made sense, so he left Wan Nian, built a sundial table and a leaky pot pavilion in front of the Temple of Heaven, and sent twelve boys to serve Wan Nian.

After a while, the son of heaven sent Ah Heng to study the calendar in Wannian.

Wannian took out his own straw calendar and said, "Sunrise and sunset are 360, so start all over again. The vegetation is divided into four seasons and there are twelve laps a year. " Jealous Aheng felt uneasy after hearing this, thinking: If I let Wannian set the festival accurately, I will be reused by the emperor. What will happen to me then? He is determined to kill Wan Nian.

So, he bought an assassin with a large sum of money to assassinate Wan Nian. However, Wan Nian worked hard from morning till night and never left Riyuege. Riyuege is heavily guarded, so the assassin can't find a chance to do it. As time went by, the assassin was very anxious. Finally, he decided to shoot with an arrow for ten thousand years.

One day at noon, when Wannian went to watch the shadow of the sun on the sundial, the assassin hid in a corner and shot at Wannian with a bow and arrow. I heard a whoosh, and the arrow landed on Wan Nian's arm. Ten thousand years later, the boy shouted to catch the assassin.

The guards arrived after receiving the news, caught the assassin and sent him to see the son of heaven.

The son of heaven learned from the assassin that the assassination of Wan Nian was originally planned by Aheng, so he sentenced Aheng to criminal law and personally boarded the Sun Moon Pavilion to visit Wan Nian.

Wan Nian pointed to Shen Xing and said, "Now Shen Xing has caught up with the silkworm period, astrology has been restored, and the children go to bed at night. The old year passed and spring began again. I hope that the son of heaven will set a festival. "

"Spring is the beginning of a year, so let's call it Spring Festival." The son of heaven said, "You have been here for more than three years. You have worked hard to make a solar calendar, which is a great achievement." Today, I was ambushed and seriously injured. Now go to the palace to recuperate with me and spend the Spring Festival with me. "

Wannian replied: "Thanks to the emperor's love, it is only a solar calendar or a grass calendar, which is still inaccurate. We must decorate the end of the year, otherwise, it will cause seasonal imbalance as time goes by. In order to live up to expectations, I must stay here and continue to set the solar calendar. "

Cold comes and summer goes, and spring goes and winter comes. After years of long-term observation and careful calculation, the solar calendar was finally worked out. When he dedicated the solar calendar to the son of heaven, the son of heaven was deeply moved by his white hair, so he named the solar calendar "perpetual calendar" and named it the longevity of the moon and the moon. Today, people call the Spring Festival "Year" and hang it in Shou Xingtu. According to legend, it is to commemorate the great achievements of ten thousand years.
