China entered its 40-day Chinese New Year travel rush, or "chunyun,"?on Jan 8 and reached its peak on Jan 19, according to official annoucement.

從1月8日起，中國進(jìn)入了為期40天的“春運(yùn)”。根據(jù)官方數(shù)據(jù)，春運(yùn)將在19日這天進(jìn)入高峰期。

Some call it the world's largest annual human migration. People spend days and nights in line at the train station to get a single ticket, but many others are never able to get on a train home.

To go even further: How has China's "chunyun" become a problem?

有人說，中國的春運(yùn)是每年世界上最大的人類遷徙。很多人在火車站晝夜排隊(duì)，只為買到一張火車票， 而有人則根本無法買到車票。與往年不同的是，今年乘客可以第一次通過網(wǎng)絡(luò)購買車票。但網(wǎng)絡(luò)購票系統(tǒng)多大程度上能緩解購票的壓力？再進(jìn)一步探究：中國的春運(yùn)如何成了一個問題？
