Those who flogged the dolphin were the ancient method of punishment. The main use of it is covered with the following numbers.
First, in the family, it is used for the training of children. The ancient etiquette, which places great emphasis on the superiority and inferiority of the eldest and the younger, and the order of human relations. If a child in the family disobeys his superiors and misbehaves, the parents use the method of flogging the dolphin to scold him, hoping that he will know and change. This is not abuse, but a small punishment and a big commandment, so that the children will remember the lesson, use the right words and deeds, and grow their moral character, so that they can obey the rules in the future, and will not go astray.
Second, between the townships and Lu, they can rectify the atmosphere. If anyone in the village commits a minor crime, such as neighborhood disputes, deception of small things, etc., the punishment of the dolphin will be imposed upon the discussion of the township husband. This move is intended to warn everyone and maintain the harmonious and peaceful atmosphere in the village. Make the villagers know right and wrong, know good and evil, and dare not easily deviate from the rules, so as to become a simple and honest hometown style.
Third, in the school, it is a means of supervision. If students neglect their studies and do not respect their teachers, their teachers can use the dolphin. The way to cover learning is due to diligence and respect. This method encourages students to study diligently, respect their teachers, and strictly abide by the rules of school, which helps to create a good style of study, so that students can concentrate on learning and achieve success in the future.
When using the method of flogging dolphins, it is also necessary to be cautious.

It is necessary to be moderate, timely, and appropriate, so that it can play the role of discipline and guidance, and not to be cruel and tyrannical.

The serpent is a supernatural thing, and its physical properties are quite peculiar.
Viewing its shape, it is often hidden in nothingness, and can be formless, like a haze, dissipating with the wind without seeing its trace. This is the unpredictable change of its shape. When it is revealed, or winding like a long rope, covered with scales and shimmering light, its scales are very hard, like cast iron, and it is difficult for ordinary swords to hurt.
In terms of its behavior, the serpent can soar through the clouds and fog, soaring above the nine heavens. Its speed is as fast as lightning, and it can fly for thousands of miles in an instant, far beyond ordinary things. When flying, the clouds and mists all around him are shrouded, accompanied by the sound of thunder, as if the power of heaven had come. Those who can control the wind and clouds must be very sensitive to the changes in the airflow, and can use the wind and cloud power to follow the trend.
Furthermore, the body temperature of the snake is also different. Its body is often warm, if the warm sun caresses it lightly, then when it is angry or uses its divine powers, its body temperature rises sharply, like a raging fire, which can turn the surrounding things into powder in an instant. And its breath contains mysterious power. Ordinary people hear it, or feel in a trance. If the cultivation is profound, they should also be treated with caution to prevent being disturbed by its breath.
As for its texture, although it is a spiritual object, it is not illusory or unreal. Touch it, you can feel it is solid, strong with muscles and bones. But its muscles and bones are not comparable to ordinary things, flexible and tough, able to bend and stretch, and can withstand huge forces and continue to break.
The physical properties of the snake are beyond ordinary common sense. The illusion of its shape, the speed of its movement, the change of its temperature, and the firmness and softness of its quality all demonstrate its uniqueness and magic as a miraculous thing, which is the wonder of heaven and earth creation.

The "Stones" article in "Tiangong Kaiwu" says: "Alum is the shape of hardware, and sulfur is the general of a group of stones, all of which are changed by fire." The genus of Arsenic is also listed. Arsenic, that is, arsenic and sand, both are poisonous, but their chemical properties are different.
Arsenic, scientific name arsenic trioxide, white as snow, highly toxic. Arsenic is produced by calcining arsenic-containing minerals in a hot fire, and its structure is stable and its chemical activity is low. When exposed to acid, arsenic can generate hydrogen arsenide gas, which is stinky and highly toxic, so arsenic is prone to chemical reactions in acidic environments. In alkaline solutions, arsenic can be dissolved to form arsenite.
Taosan is a natural mineral of ammonium chloride, with a white or yellowish color and a salty and bitter taste. Taosan is easily decomposed when heated to form ammonia and hydrogen chloride gases. Taosan is hygroscopic and easily deliquescent in humid air. Its aqueous solution is weakly acidic due to the hydrolysis of ammonium ions. Taosan reacts with alkali to produce ammonia quickly, which is its significant chemical property.
Arsenic and Taosan, although both are obtained from "stone", are stable and highly toxic oxides, and salts that are easily decomposed when heated. The chemical properties of the two are very different. Looking at these two, we can see that under the fire, the transformation of minerals is infinite, each with its own characteristics and its own transformation.

Those who keep the treasure should pay attention to the general matters when they are hidden. The hidden things, or the treasures, or the important things, are easy to be damaged and lost if they are not careful.
First of all, it is necessary to make a proper report. This is suitable for dry weather, if the tide is rough, the hidden things are easy to grow and decay. For example, gold beads, when the tide is wet, the color is; If it is a weapon, it is easy to collide with it. If it is a precious artifact, it may not rub against each other and hit its surface.
And it needs to be guarded. It can be hidden in the dark, or set up for inspection. There is heavy security. If it is not well guarded, it will inevitably be hidden. The wealth of ancient times, hidden in secret chambers, there is still the risk of robbery, all because the protection is not secret.
At the same time, regularly check the hidden things. Check for signs of damage and damage. If it is eaten and hidden, it is necessary to check for moths and mildew; collection, and also to keep the hidden things in good condition.
In this way, the location, order, prevention, and security of the hidden objects must not be ignored, so that the hidden objects can be preserved for a long time without losing their usefulness.

The method of making turtle armor has been known since ancient times. The method is as follows:
First take the turtle armor, wash it with water, and remove its mud. Then, put the turtle armor in a kettle, add an appropriate amount of water, and boil it over fire. When cooking, pay attention to the heat, and do not use it too much or too little. When the meat of the turtle armor is easy to peel off, remove it, and discard its meat, leaving only the armor.
Then rewash the obtained armor with water to remove the remaining meat chips. After washing, dry it in the sun.
After that, put the turtle armor on a tile and bake it over a slight fire. When baking, keep turning it over to make it evenly heated until the color of the turtle armor turns yellow and the quality is crispy.
Another method is to stir-fry with sand. First take the clean sand and put it in a pot, heat it up over high heat, and then put the turtle armor into the sand and stir-fry it continuously. The heat of the sand can make the turtle armor quickly heated, stir-fry until the turtle armor bulges, the surface is golden yellow, take it out, and sift off the sand. At this time, the texture of the turtle armor is crispy, and it is easy to crush and fry out the active ingredients.
There is also a method of quenching with vinegar. The turtle armor fried above is put into vinegar while it is hot. The amount of vinegar depends on the amount of turtle armor. Generally, about 30 catties of vinegar are used for every 100 catties of turtle armor. When the turtle armor is put into vinegar, there is a sound of "swoosh". When the After quenching with vinegar, the turtle armor is not only more crispy in texture, but also vinegar can be introduced into the liver to enhance the effect of softening and loosening the turtle armor.
All these methods are commonly used in the preparation of turtle armor, so that the turtle armor can meet the requirements of medicinal use and maximize its efficacy.
