What does it mean that "people are poor and lose their tongue, and the weather is dry and lose their yin and yang"?

The previous sentence said that if people are poor, then what you say has no weight, that is to say, people speak lightly.

The last sentence means that if it is drought and there is no rain, there is no difference between day and night, that is to say, yin and yang are unbalanced.

This is a literal meaning, but it actually has an extended meaning. The first sentence, people are short-sighted, people speak lightly and are easy to understand. The second sentence is about heaven, which also refers to the laws of nature. If the law is broken, everything in the world will lose its original order, and disorderly nature will become a space that is no longer suitable for our survival. This sentence is telling us not to try to break the laws of nature, which is suicide.

If these two sentences are said to you by someone else, I can understand that he is asking you to make progress, but you should abide by the rules and regulations when making progress. Don't be too opportunistic and destroy the natural development law of things, otherwise it may be counterproductive because of quick success and instant benefit.

If this is what the fortune teller said to you, then he should mean that you are a humble person now, but you are trying to participate in things that are not your identity, making things more complicated and out of control.
