春运

The Chunyun， or Spring Festival travel rush， is a large-scale transportation phenomenon in China that occurs around the Chinese New Year. It typically starts 15 days before the holiday and lasts until about 25 days after. During this period， hundreds of millions of Chinese people travel back to their hometowns to reunite with their families. The volume of passenger traffic far surpasses the annual peak of any other country， earning it the title of "the largest human migration on Earth." The government and relevant departments implement a range of measures to ensure smooth and safe transportation. Chunyun is not only a major event in Chinese society but also showcases the capacity and organizational efficiency of China's modern transportation system.

春运是中国在农历春节前后出现的大规模交通运输现象，通常从春节前15天开始，持续到节后25天左右。其间，数亿中国人纷纷返乡与亲人团聚，客流量远超其他任何国家的年度交通流量峰值，因此被称为“地表最大规模的人口迁徙”。政府及相关部门会采取一系列措施，确保交通畅通和安全。春运不仅是中国社会的重要事件，也展现了中国现代交通运输系统的承载能力和组织协调水平。
