Well, it is easy. They do the markings themselves :)
Beijing, the capital of China, is a very busy city and it is almost impossible to find a spot to park. So people are bringing some king of handmade “carpets” that match the color of the road with parking markings and then they put a fake parking sign and voila.
The police say they can only arrest these people if they catch them red-handed, otherwise they don’t touch them.
Here’s the process of faking a parking spot :)
Take a look.
