The Spring Festival, China’s largest festival, is almost here! For Chinese, this is a time to end their wandering and return home to be with their family and friends. This year, the Spring Festival falls on Jan. 28, so at this point, most Chinese have bought tickets and are packing airports, train stations, and bus stations as they head back to the familiar sights, sounds, and smells they call home.

On Weibo, Chinese netizens are using the tag 世界再大也要回家 (shijie zaida yeyao huijia) to post photos of their journey back home. The Weibo tag opens a window into the Spring Festival travel rush. Already, the tag has been used more than 90 million times. What does the tag mean? It means no matter how big the world is, gotta go home.

The Spring Festival travel rush is the world’s largest annual human migration. Already this year, the travel rush set a new record. More than 83 million passengers were transported safely on Jan. 23 alone. China is expected to transport nearly 3 billion passengers over the 40 day period from Jan. 13 to the end of Feb. 21.

Returning home for the festival is a lot of work, but for Chinese the effort is worth it. The Spring Festival marks the beginning of the Chinese New Year and it is the only time of the year when all family members get together. As we speak, millions and millions of people in China are going home, and many of them are sharing that experience with the world online.
