Wow, pretty good deal for the company. Though one wonders how much work was actually done after 5...I think you missed his point completely. I think he was trying to say people in China (like him) may have worked 'overtime' for personal convenience reasons (like ease of commuting), not because the company asked them to. He was commenting on 997.
Many people in my old Firm (in New York), worked after 8PM so they can get free dinner and a car service ride home.
