Chinese New Year, also known as Spring Festival, is the most significant traditional holiday in China. It is celebrated on the first day of the Chinese lunar calendar, which usually falls between late January and mid-February. 

The origin of Chinese New Year can be traced back to the Shang Dynasty (1600 BCE - 1046 BCE) when people held sacrificial ceremonies to pray for a good harvest. During the Zhou Dynasty (1046 BCE - 256 BCE), the customs of New Year gradually formed, such as ancestor worship, religious rituals, and house cleaning. It was not until the Han Dynasty (206 BCE - 220 CE) that the term "Spring Festival" was first used. Since then, the celebration of Chinese New Year has become a national and cultural event that is widely celebrated across the country and around the world.

There are many traditional customs and activities associated with Chinese New Year. One of the most important is the reunion dinner, which is held on New Year's Eve. Families gather together to enjoy a feast of traditional dishes, such as dumplings, fish, and sticky rice cake. Another important custom is the giving and receiving of red envelopes. These packets, filled with money, are usually given to children and unmarried adults as a symbol of good luck and fortune.

Decorations are also an integral part of Chinese New Year. Red is the dominant color, symbolizing happiness and good luck. House cleaning and decorating with red lanterns, couplets, and paper cutouts are also popular activities. Additionally, it is customary to set off firecrackers and lion and dragon dances are performed to ward off evil spirits and bring good fortune.

The 15-day period from the first day of the Chinese New Year to the Lantern Festival is considered to be the Spring Festival period. Each day has its own significance and associated customs, such as visiting family and friends, lighting candles and incense, and attending temple fairs.

In conclusion, Chinese New Year is not only a time of celebration, but also a time of connecting with family and friends, remembering ancestors, and looking forward to the future with hope and positivity. Its long history and rich traditions make it one of the most important cultural events in China and around the world.
