Is four-column prediction easy to learn?

Everything is predestined. To learn this kind of thing, first of all, you have to ask yourself whether you want to study for life, whether you have the patience to bear the blow, and whether you have the determination to take a pen with nails. If you don't or give up halfway, then you are also a person who is deceiving yourself and preparing to deceive others ... In this case, I beg you not to learn, because the reason why Yi-ology is often called superstition by others is that those who only fill half a glass of water and then pretend to be masters in front of others often fail to make accurate results and are misunderstood! Especially feng shui, if you don't master it, you can play it. It doesn't matter if you hurt others. The key is to hurt yourself. If you can't do it well, you will be at a loss. If you are serious, you will play yourself to death. This is immediate and unreasonable. So if you want to study, you should ask yourself what I mentioned earlier. This is what goes around comes around.
