Chinese travellers wait to catch a train at the West Railway Station in Beijing, China, Thursday, Jan. 19, 2012. Millions of Chinese are expected to cram onto China's bus and train network to return home for the Chinese Lunar New Year which falls on Jan. 23, 2012.

BEIJING — Desperate to return home for China's most important holiday, migrant worker Li Zhuqing lined up for six chilly days and nights at a train station ticket counter only to be told that all the seats were sold out.

Reports of Li's plight in Hangzhou prodded local media to help Li and his family travel home after his case touched a nerve in China, where getting home for Lunar New Year is a nightmare for tens of millions and represents the world's largest seasonal migration of people.

However, a new twist has been added this year with the introduction of online train ticket sales: Many of the country's less-computer-savvy migrants like 48-year-old Li seem to have been left out in the cold.
