I actually shot this on the third night (28th) I arrived in Nanjing; but I’ve just recently secured a stable connection to Youtube.
The group of cyclists are waiting properly in the designated bicycle turning box.
When I was growing up in Nanjing, interesections had no lane markers for bikes. I think it’s a good idea to try to set a traffic protocol for bikes. But even if it works, I just couldn’t believe the waiting box is in the middle of the intersection.
