Is the mobile phone number accurate for good or ill luck?

Not allowed. After all, Five Elements and Daoism are metaphysics in China. Different people have different opinions. This is just a psychological effect.

It's not credible at all. I once counted the number of people I know on one website, and they were all fierce. Then I went to another website to count them, and most of them were lucky. Besides, the number you are using may have been used before. Who may use it now? Are we all the same fate?

In theory, I'm afraid it's hard to say whether it's credible or not, but I can tell you that it's hardly credible in practice. Just like other fortune tellers.

In fact, you only need to use your head a little to know how unreliable fortune-telling is. Let's not talk about this mysterious thing. Let's talk about housework in daily life. Some people do it quickly and well, others just can't do it well, even if they sweep the floor, they can't clean it. Analogous to fortune telling, we might as well assume that everyone has an unknown fate that determines our life, but who knows?
