What is Yanjiao going to Beijing to check by bike?

Yanjiao people can swipe their ID cards when commuting to Beijing, but they need to apply for a Beijing work certificate or a Beijing-Hebei pass. They must do it themselves, not their families. Yanjiao cyclists who need to commute to handle documents will put their ID cards on the gates and brush them when they pass through the gates in an orderly way in the rightmost dedicated passage, and they can enter Beijing when they hear the prompt.
