Baidu's spring migration map – China's biggest search engine, Baidu has released an interactive, real time Qianxi (or Migration) Map that tracks movements around the country during the Spring Festival travel rush. The most popular routes on February 3 appear as yellow lines.
Outbound movements – Being major cities with significant populations of migrant workers, Shanghai and Beijing have been seeing the most departures since spring migration began on January 24.
Road traffic – Baidu also worked with China's traffic management bureau to track the country's roads. This map shows the section with the worst congestion -- the Suzhou portion of the Beijing-Shanghai Expressway.
Crowded attractions – Another handy feature of the map allows travelers to find out how crowded a specific attraction is. For instance, this snapshot of the map shows that Jing'an Temple in Shanghai is currently "very packed."
Traveling in Beijing? – Beijing's National Museum of China, on the other hand, is graded as merely "packed."
