No matter what transportation tools they take, all Chinese have the only wish during the Spring Festival travel rush - returning home. The spectacular migration of population every year in China also reflects the development of the society and economy. Spring Festival, or better known as Chinese Lunar New Year, is the most important festival for all Chinese, which has a history of more than 4,000 years. It is an occasion for home returning, New Year goods preparing, celebrating, and foremost, family reunion. (Xinhua/Xiao Yijiu)
