A seven-year-old girl holds a sign that reads "Chef, cook assistant, waitress, apprentice, vegetable cleaner needed" on Feb. 1, 2012, on a labor market in Hangzhou, Zhejiang Province. She helps her father look for workers who are available during the Spring Festival period. The Spring Festival, Chinese traditional New Year, is the nation's most important festival. Days before the festival, almost everybody, especially migrant workers and overseas Chinese from across the world, travel home to reunite with their families.
