"Alas! In today's society, it's really difficult to do something good, and sometimes you have to be angry when you contribute money and effort. ”

"Originally, our investment in sewage treatment was not small, but it was still within the scope of our control.

But now the follow-up questions that arise from this are not something that you don't want to do, it's just a bottomless pit.

Why should we solve something that even ZF can't do? ”

"It's just not fair!"

"Let's not talk about this unfair issue, dwelling on the root causes will not help much to solve this environmental pollution problem, it will only make the problem more complicated.

Let's go back to the previous cause of the cross-flow of sewage, since people can't help but produce sewage, why do people always dump that sewage around? Why not pool the sewage and treat it? ”

Chen Xiaohua said: "The quality is low. ”

Liu Mengling said: "Selfish, only for their own convenience. ”

Wei Minsheng said: "In fact, Mengling's 'only for her own convenience' can be regarded as finding the crux of the problem.

No matter how good the quality is, if the street is full of garbage and you can't find a garbage can, you can only put the garbage on your hand in the place with the most garbage.

Those farmers' markets have the most sewage, especially those fish stalls, which produce a lot of sewage every day, but if the market doesn't have a supporting sewage collection and treatment facility, where do you let them dump the sewage? The more convenient the better.

While anyone dumping sewage has an impact on the environment, which is a bad thing, there are also pros and cons to the bad side.

The pros and cons of dumping sewage should be based on the severity of the environmental impact, and it is certainly much better to dump sewage into a septic tank than to dump it directly into a ditch.

We only need to find the cause of this pros and cons, and find a reasonable way to solve it, which was called the 'Five Elements Theory' in ancient times. ”

"What? How did you come up with another 'Five Elements Theory'? ”

"Can you start by saying what you mean by the five elements? This time, let's talk about it by Li Wei. ”

"Five elements? I only know what it seems to be, but I don't know what it means. ”

"The five elements of gold, wood, water, fire, and earth are very awesome things in many film and television works or novels, and any cultivator who has the spiritual root of the five elements will definitely become the existence of the world.

However, the theory of the five elements in reality is not so mysterious, it believes that everything in the world is the result of the movement and change between the five basic conditions of metal, wood, water, fire and earth.

At the same time, it also uses the relationship between the five elements to explain the interconnection between things, believing that nothing is isolated and static, but maintains coordination and balance in the continuous movement of mutual generation and restraint.

This is the basic meaning of the Five Elements Theory, which was annotated by the old Chinese medicine practitioners after the founding of the People's Republic of China in order to show that the thought of Chinese medicine has materialist characteristics.

In fact, there are many opinions about the five elements, and there is not even a single theory on the origin of this doctrine that everyone agrees on.

The most popular view is from Shangshu? Hong Fan", which argues that people abstractly summarize things with similar properties in nature and classify them into the five elements, and then use the mutual relationship of the five elements to explain the changes of things.

Another view is that the five elements originate from the mantra of heaven and earth generation in Hetu and Luoshu: 'Heaven is born of water, and the earth is sixty percent; The earth is two fires, and the heavens are seventy; Heaven is three trees, and the earth is eighty percent; The earth is four gold, and the sky is ninety; Heaven gives birth to five earth, and the earth is ten percent. ’

"The Yellow Emperor's Inner Canon? Su asked? The Great Treatise on Yin and Yang should be like the Great Treatise on the Five Elements believes that 'the east gives rise to wind, and the wind gives rise to wood', 'the south generates heat, and heat produces fire', 'the center produces dampness, and dampness produces earth', 'the west produces dryness, dryness produces gold', and 'the north produces cold, and cold produces water', and the qi of the direction produces the five elements.

There is also a view that the five elements are related to the Yin and Yang doctrine of the Book of Changes, which I also agree with very much, because when talking about the five elements, they basically need to be combined with the Yin and Yang doctrine to be able to elaborate.

The most important idea in the Five Elements Doctrine is the relationship between life and restraint, which refers to the fact that wood begets fire, fire begets earth, earth begets gold, gold begets water, and water begets wood.

Xiangke refers to wood and earth, gold and wood, fire and gold, water and fire, and earth and water.

The so-called shengke actually refers to the relationship between two things that affect each other, the living is beneficial to it, and the restrained person is disadvantageous to it.

The pros and cons are essentially the yin and yang in the theory of yin and yang, so the five elements of yin and yang are an inseparable whole, and without yin and yang, the five elements have no meaning.

In my opinion, the Five Elements originally came from Zou Yan's understanding of the 'Six Relatives', because the Five Elements mainly discuss the relationship between the five elements of metal, wood, water, fire, and earth, which has a surprising coincidence with the relationship between the 'Six Relatives'.

The 'six relatives' used to refer to oneself, parents, brothers, sisters, wives, and descendants.

If you think of yourself as fire, then your parents are wood, because wood makes fire; The offspring are the earth, because fire gives birth to the earth.

Among brothers and sisters, there is naturally a competitive relationship, and this competitive relationship is not good for oneself, so it can be regarded as mutual restraint.

Those who can suppress themselves among brothers and sisters are called self-denial, and those who can suppress themselves among brothers and sisters are called self-denial.

In the same way, if you think of yourself as fire, then the one who overcomes me is water, because water overcomes fire; I conquer gold, because fire overcomes gold.

If we diverge this relationship and apply it to other things in the world, and use its laws to analyze the influence of related things on it, this is the current Five Elements Theory. ”
