TOKYO/NAGOYA/OSAKA/ SEOUL/HUIZHOU, China -- It is 5 p.m. on a weekday in Huizhou, a lake-studded city in China's Guangdong Province, and workers are streaming out of a BYD manufacturing plant looking weary after a day's work. Many head straight for the crowded street food stalls lined up in front of the factory for after-work noodles and drinks.
"No matter how much overtime we work, we still have a manpower shortage," said one worker.
