Learning strange things is a problem? Whether using a turntable or a frisbee, repairing or jumping,

Both can be used, both can be accurately measured, and neither can be accurately measured 100%. It's all based on Hetuluo's books. I'm not fixed. I just want to buy Run, which is located when viewing the sun, because there have been some situations in actual combat, and this kind of disk is more accurate. Sometimes one of the other plates is missing. So I don't have to. In fact, this is also the result of actual combat. But many experts know what the parties use, but many only know frisbee. The ancient method admits that the frisbee is another one, and some people say it is very accurate. And my friends, who have studied Temen for more than ten years, just don't recognize Frisbee and think the principle is wrong. In short, they use their own methods and means. And technology is artificial, and people can't see through it. A model is always a model and cannot represent all states, so neither of them will be 100% accurate.
