Strictly speaking, patents are not. Anyone can play.
1. In foreign countries, golf is a mass sport, and its consumption is not as high as that in China. Playing golf is more like and casual. Some stadiums don't even have caddies, so they have plenty of food and clothing. Just drag the club and bring the cart. Of course, this informality doesn't mean that you don't follow any manners, but you still have manners.
2. People who play in China are really rich or expensive. Because playing ball is expensive, most people can't afford it. But that doesn't mean it's a patent for the rich. You can try it if you want.
Come on, so can you!
