Road etiquette in rural China

In the UK it’s generally excepted that the line in the middle of the road is a separator. It keeps cars, busses and bikes that are going in opposite directions from crashing.
In rural China the line in the middle of the road is more of a guide that is used to tell you where to drive (assuming there is a line). When there is a blind corner, just use your horn. Simple.
This makes any kind of taxi or bus ride an excercise in mental strength as much as a means of transport. I don’t even want to get started on the roads in towns thats just a hellstorm of chaos.
