春运是中国春节期间的一项重要活动，因为很多人会在这个时候回家团聚。春运通常从春节前开始，一直持续到春节后的一段时间。具体来说，春运的开始时间和结束时间因地区而异，但一般来说，春运会在正月十五左右结束。在这个时候，大多数人已经完成了他们的春节回家之旅，开始重新投入到工作和生活中。

The Spring Festival travel rush, or Chunyun in Chinese, is an important event during the Chinese New Year as many people return home to reunite with their families. Chunyun usually starts before the Spring Festival and lasts for a period of time after the festival. The exact start and end time of Chunyun varies depending on the region, but generally, Chunyun will end around the 15th day of the first lunar month. At this time, most people have completed their Spring Festival travels and begin to return to work and daily life.
