From January 26 to February 5, 2008, a sudden cold wave made Guangzhou, the Flower City, look like a northern country. Hundreds of thousands of passengers were stranded at Guangzhou Railway Station, and their hometown was calling the hearts of every traveler. No one knew when the train full of dreams of reunion would arrive. This was the most unforgettable Spring Festival travel in Guangzhou's transportation history. Countless passengers fainted, cried, and shouted. In times of crisis, tens of thousands of police officers formed a human wall with their bodies to maintain order and ensure safety. During the 11 sleepless nights, their eyes were bloodshot, their lips were chapped, and their voices were hoarse. The 11 sleepless nights brought the hearts of the police and the people together.
