How to write the origin of the Spring Festival in 50 words?

Spring Festival is a traditional New Year in China, which originated from the activities of offering sacrifices to gods and praying for blessings in ancient times. According to legend, in ancient China, there was a fierce beast called Nian, which would come out to eat people every twelfth month. Later, people found that young animals were afraid of red, noise and fire, so they began to post Spring Festival couplets, light lanterns, set off fireworks and eat New Year's Eve dinner every year to pray for peace, auspiciousness and happiness in the new year. These customs have continued to this day and become the symbolic activities of the Spring Festival in China.
