請將下面這段話翻譯成英文：
“春運(Transportation during the Spring Festival Period )”被認為是規(guī)模最大的年度遷徙。這是個特殊的時期，這時的中國面臨著極高的交通負荷，從而導致巨大的交通問題，特別是在鐵路服務方面。在春節(jié)臨近的時候，數以百萬計遠離家鄉(xiāng)工作或學習的人要趕回家與家人團聚。這個長久以來的傳統(tǒng)是春運高峰的主要原因。還有一個原因，這個假期是每年兩個為期一周的長假中的一個，對許多人來說是一個外出旅行的完美時機。
參考翻譯

Millions of people working or studying far away from their hometowns will come back home to reunite with their families as the Chinese Spring Festival approaches.This long-held tradition is the main reason for the rush.The other is that the holiday is one of the two long holidays of one week in the year, and for many people,it's a perfect travel time.
