In "Tiangong Kaiwu", the main use of 2-Jiang-5 grains is for fermentation and storage of distiller's grains in the winemaking process.
The old grains, in the winemaking industry, have a special function. When making wine, the rice is cooked, thrown into the grains, mixed with koji, covered and sealed, so that it can be fermented. The grains are fermented, and the internal environment is suitable for temperature and humidity. When the koji and rice are in this good condition, biochemical changes occur, and the sugar gradually turns into wine.
To be fermented, the grains are both finished, and the grains are also used for storing distiller's grains. The distiller's grains, although the leftovers of winemaking, are also widely used. One, can feed six animals. All kinds of livestock can be fattened by food. Second, after proper treatment, it can also be fertilizer for farmers, nourishing the soil, and helping crops, fruits and vegetables thrive.
Therefore, it is indispensable for winemaking and related matters. It is related to the success or failure of winemaking, and also involves the utilization of subsequent resources, which is beneficial to people's livelihood and industry.

If you want to combine the 2-river-5-river, the method is correct. The clever workmanship and the good quality of the materials are all good for the combination. The following is a brief description of the method.
First, the method of mortise and tenon. Good materials, fine mortise and tenon, so that the 2-river-5-river fit. First measure its shape, and use it to make a mortise and mortise. The mortise should be fixed, and the mortise should be fixed. The two are interlocked, like the earth made by heaven. This method requires the skill of craftsmen and the fine measurement, so that the two can be solid and will not last for a long time.
Second, the method of sticking. In this world, there is a good way to help. The strength of this force should be determined by the connection of 2-river-5-river, and the thickness and thinness of the wood should be combined. However, the amount of water should be appropriate, and more overflow and less instability should be used. And the water resistance and weather resistance should also be considered, so as to make it fit in different environments.
Third, the method of connection. Take 2-river-5-river, so that it can be combined. It is suitable to be short and thick, and the thickness and thinness of the wood depend on the force. Use the wood or the wood, and the wood should be vertically flat, so as not to crack the wood. This is an easy way, but also pay attention to the arrangement of the distance, so as to equal the force.
Fourth, the method of welding. If 2-Jiang-5-

Mercury, commonly known as mercury, is a liquid metal with special physical properties.
It is silver-white in color and a flowing liquid at room temperature and pressure, which is different from most solid metals. This is a significant physical property. In "Tiangong Kaiwu", mercury is volatile and gradually disperses in the air in an exposed environment, because its boiling point is only 356.73 ° C, which is low.
Mercury has a high density, about 13.59 grams/cubic centimeter. When placed in other common liquids, such as water, it will sink rapidly. The book also states that mercury can dissolve a variety of metals and form amalgam, which has been used in metallurgy and other fields for a long time.
Mercury has certain toxicity. Although the "Tiangong Kaiwu" does not describe its toxicology in detail, it says that the relevant mining and use need to be cautious. Prolonged exposure to or inhalation of mercury vapor can damage the human nervous system, kidneys, etc. Mercury was a common raw material in ancient alchemy, and some alchemists suffered health damage due to long-term exposure to mercury and its compounds.
Mercury has good electrical conductivity and is used in the electrical industry. In the era of "Tiangong Kaiwu", although it was not as widely used in electricity as in modern times, its electrical conductivity properties can be inferred from the common conductivity of metals, which laid the foundation for later cognition and application.

The price of the five stones in the Guanfu Gorge is quite difficult to determine. The types of stone are diverse, and their quality, shape and color are different, all of which are related to the price.
If the stone is warm and delicate, and the tentacles are warm, just like suet jade, the price will be very high. Just like the warm gorge stone that came out in the past, everyone in the city competed for it, and the price also rose, reaching thousands of gold.
And its shape is like a natural interest, or like a auspicious beast, or like a fairy mountain, such strange stones are also popular with collectors. There used to be a stone like a auspicious dragon coiled around, traded in the market, and the price was hundreds of gold. If its color is bright and eye-catching, or emerald green like a verdant feather, or vermilion like Danxia, it can also increase its price.
However, the place where the gorge stone is located is different, and its price is also different. Those who are close to the market, because it is easy to trade, the price may be slightly higher; in remote places, although the quality of the stone is excellent, the price may be suppressed due to the difficulty of transportation.
And the rise and fall of time also affects the price of the stone. In a peaceful world, the people are rich and easy to play, and the price of the stone is always high; if there is a war and chaos, and people's livelihood is difficult, although the rare stone is rare, the price is also difficult to recover.
Furthermore, the calculation of stone merchants also affects the price. Those who are good at camping can show the wonders of stones and attract attention, but the price can rise; those who are poor at camping, although there are beautiful stones, the price is difficult to show its value.
The market price of five stones in the Two Gorges is as low as tens of gold, and as many as thousands of gold. It depends on the quality, shape, color, land, and world luck, and various factors that are intertwined to determine the price.

If you are in the second or fifth cannon, you should pay attention to it when you are hiding it.
It is the first time to hide it. Artillery is a delicate and powerful thing, suitable for hiding in a busy place. If you are in a difficult place, it is easy to produce, and it is sensitive to its machinery. And the gun body is made of gold, and it is born in contact with water. Over time, it will be weak, and the power of the shadow shot will be weak. And the quality of the room also needs to be determined. The height of the gun body is easy to make some parts of the gun body expand, which affects its fit. The low quality may change the performance of the gun and other physical properties, which is not conducive to the use of the day.
Furthermore, the method of stacking cannot be ignored. The body of the gun is large and heavy, and it is not easy to be stacked, and it is easy to collapse, and it is difficult to damage itself, even to endanger the surrounding objects. According to the size and weight of the gun, it should be stacked in an orderly manner, and enough passages should be left for inspection and use.
When it is difficult to get there, the bumps in the road are a big problem. If the road is rough and the shock absorption is not good, the gun body will not be shaken on the way, and the parts of the gun may be damaged as a result, and the impact will be determined by the day. And on the way, the prevention should also be carried out. It needs to be covered with shelter to prevent the rain and sand from invading and causing the gun to be damaged.
Also, there needs to be a person on duty to inspect. In the case of hiding, check the shell of the gun body and the environment of the room at a fixed time; in the case of hiding, pay close attention to the operation of the gun and the fixed situation of the gun. If there is a slight mistake, it is feared that there will be a big problem. This is the important thing to pay attention to in the case of the second and fifth cannons.
