Chinese Year of the Dragon to Bring Good Luck

In China, New Year celebrations set off the world's largest annual human migration, with 3.2 billion journeys expected in the next 40 days. Most will be urban workers going home to their families, though Spring Festival vacations are increasingly popular with affluent urban families. This is the Year of the Dragon, said to be the ancestor of all Chinese people and the only mythological animal in the Chinese zodiac. Wei Hong, Professor of Chinese and Director of the Confucius Institute at Purdue University, who spends a lot of time helping American businesses work in China, tells us what to expect.
