At each factory we enjoy lunch in the on-site VIP dining hall with our hosts. A single factory can employ and provide dormitory housing and dining facilities for more than 50,000 workers. Contrast that to the population of Concord which is 15,000. iRobot products require more than 2000 workers to assemble and test. After completing our meetings and tours we hop on a ferry and make the 90 minute voyage back to Hong Kong.
