What does Dan mean?

"One Dan" is an idiom, which is often used in ancient Chinese to describe a state: at dusk, the sun is just about to set. It can also be used to describe the last stage of a thing or a person, such as "The last stage of life is a Dan".

In the traditional culture of China, time is divided into 24 solar terms, and "Yi Dan" belongs to one of them-slight cold solar terms, which means that when the cold winter comes, everything begins to recuperate and hibernate to accumulate energy. This is also an important time node for farmers in China's agricultural production, so the related cultural and festival activities are also very rich.

With the constant changes of modern life, people's understanding and application of culture are becoming more and more diversified. In today's society, "one Dan" is gradually used to describe the end of a certain period or an event, or the end of someone or something. For example, in the internet world, "One Dan" is used to describe the final state of an APP or social media platform, while in the sports field, "One Dan" is used to describe the retirement or defeat of an athlete or team.
