More Chinese are choosing to travel during Spring Festival rather than return to their hometowns for family reunions, a break from one of China's most important traditions.

Since the late 1970s, Chinese have been finding jobs and settling down in economically developed cities outside their hometowns. However, Spring Festival remains an important time for family reunion. Consequently, for decades, there has been a massive movement between where people work or study and their hometowns during the 40-day travel peak.

This year, 2.98 billion journeys are expected to be made during Spring Festival.
