A day you can date Foster. Shenzhen is gearing up for the APEC summit, with volunteers holding signs in the streets encouraging drivers to spend a day without a car while giving way to guests. Authorities are asking car owners to stop using their vehicles for one or more days between November 16 and 20. A poster on one office building read: "In order not to create problems for the APEC conference in Shenzhen, please choose a way to donate." Among the ways "work overtime until late at night", "leave the car", and "turn the commute to work into physical exercise". After a flurry of ironic comments, the poster was removed. The Chinese threat.
