I was walking by Causeway Bay in a very busy area where I see a vehicle with 4 parking tickets on the windshield.
As you can see from the first photo, it is parked along the part of the street that had double yellow lines, plus it is about 5 feet from the traffic light.
I was told by an parking enforcer that as long as there are no parking meter all streets in Hong Kong are no parking, and sections of the road with double yellow lines means no stopping 24 hours a day.
In most cities that I know, 3 is the limit that any parking enforcers will ticket a car, after that either the car is booted or a toll truck would be called to remove the car in question.
When I was a police officer in Canada, after two tickets we would check to see if the car was stolen or worst.
