How does this actually work?

The video below is from a typical intersection in Guangzhou. Traffic is coming from my left - and then also from my right, meeting at a right angle at the intersection.

To start - you see the traffic coming from the left. However - look at the traffic light above the yellow bus. It's green - and that's for the traffic from the right. As I pan the camera, you can see the traffic from the right moving - and you can see the light green as well for the traffic coming from the left.

The one thing to know is that the traffic from the right can not go straight; it's a one-way street coming at the intersection.

So we have green lights all over the place, cars heading straight and turning right into the same lanes - and it all somehow seems to work. Fascinating if it's not so scary.
