Xin means the official beginning of dry autumn in the calendar. Among the 24 solar terms, Xin is the first solar term in autumn, and it is also a symbol of hard and dry autumn. At this time, the weather began to turn cold, the autumn was crisp, and everything began to enter the harvest season. For many people, the new symbol means that they can enjoy beautiful autumn days and start activities, such as enjoying red leaves, walking or picking fruits.

In the folk, Xin also has a lot to do with keeping in good health on the calendar. People in China have paid attention to health care since ancient times, and it is also the time when people began to pay attention to health care and adjust their lives. The temperature changes greatly in autumn, so people need to pay attention to keep warm and supplement nutrition. At this time, eating more health food, eating more fruits and vegetables and exercising more are all practical methods.

In China culture, the new calendar has another cultural connotation. Xin belongs to gold in the five elements, representing precious metals and symbolizing strength and money. Therefore, in some fields, people like to do things related to wealth, such as managing money and buying valuables. In addition, Xin also represents pomegranate, which is as red as fire and symbolizes auspiciousness and prosperity, so pomegranate is used as a sacrifice in some places.
