The main application fields of this product are quite wide, involving many aspects such as agriculture, military, construction and daily use.
In the field of agriculture, it can be used to assist agricultural labor. As "Tiangong Kaiwu" said: "It is the weight of grains (grains), and the people and the sky are also." Crop planting, from sowing to harvesting, can use this product to improve efficiency in many links. When sowing, the amount and spacing of sowing can be precisely controlled, just like the old farmer's experience, the grains are in place; when irrigation, it can rationally allocate water resources according to the water demand of crops, and keep the seedlings thriving, just like the ancients carefully used canals to irrigate the fields and nourish all things.
Military aspects, its role should not be underestimated. " Soldiers are also tricky. "Marching and fighting, terrain detection, military information transmission, etc., can all borrow this product. It can help generals quickly grasp the enemy's defense and mountain and river terrain, just like ancient scouts accurately detect the enemy's situation, providing a key basis for the layout of the war, making the use of tactics more flexible and changeable, and decisively better than thousands of miles away.
In the field of construction," Tiangong Kaiwu "said:" Where a house is built, wood must be treated first. "This product can play a role in wood processing, masonry and other links. It can assist in precise cutting and tight splicing. For example, in ancient times, skilled craftsmen built pavilions with exquisite skills, making the building more sturdy and durable, and it will not fall over time.
In daily use, it is also indispensable. At home, it can assist in the production of exquisite utensils, making life more convenient. "Utensils carry the way", from daily utensils to exquisite decorations, can be created with it to improve the quality of life, just like ancient folk craftsmen carefully carved all kinds of utensils, enriching people's lives.

The method of combining a certain spiritual object is quite mysterious, and let me explain it in detail.
At the beginning of its method, it is necessary to find a place where the wonders of heaven and earth gather. Such a place, or a place where mountains and rivers are victorious, there are clear springs gurgling, beautiful trees are lush, and the spiritual energy is dense; or between the gullies of ancient caves, after years of precipitation, the essence of the sun and the moon can be absorbed. In this place, the beginning of the synthesis can be started.
Then, all kinds of spiritual objects need to be picked. This spiritual object, unusual grass, wood, gold and stone, must have unique endowments. For example, the thousand-year-old Ganoderma lucidum, born in a damp place on a cliff, gathers the warm and moist qi of heaven and earth, has a purple color, a solid texture, and a clear fragrance and refreshing spleen when smelled; or like the deep-sea mackerel beads, which are transformed by the sobbing tears of the mackerel people, crystal clear, containing the deep power of the sea, and flowing brightly. When collecting, when it conforms to the time of day, take it according to its physical properties, and do not act rashly, so as not to damage its spiritual energy.
Then, place all kinds of spiritual objects in a special cauldron furnace. This cauldron furnace is made of fine gold and jade, and its shape is simple and simple. It is engraved with runes and incantations The bottom of the cauldron is lit with a spiritual fire. This fire is extraordinary, either transformed by the flame pulp of the earth's core, or the embers of the divine fire of Tiangang. The fire is fierce but not dry, and can refine the impurities of spiritual objects and fuse their essence.
When combining, the operator needs to have no distracting thoughts in his heart, and use his spiritual thoughts to guide the fusion of the essence of the spiritual object. Observe its heat, observe its changes, and adjust it in a timely manner. When the essence of the spiritual object blends, there may be strange rays of light blooming, or there may be faint sounds of nature. These are all key nodes of the combination, and there is no room for failure. When the essence of the spiritual object is integrated and turned into a spiritual liquid, the work is done.
This method of integration requires the operator to have a deep spiritual power cultivation base, and to have a subtle insight into the nature of spiritual objects. If there is a slight mistake, all previous efforts will be wasted. All kinds of things in between are actually the wonders of creation in heaven and earth, and non-casual people can easily do it.

In order to ensure the purity of the product, you need to do everything to improve its quality. In the past, "Tiangong Kaiwu" mostly talked about the system of various things, and there are also lessons to be learned in the way of maintaining purity.
Where the purity of the product is guaranteed, the first thing is to select materials. Material is the basis. If the material is not pure, the finished product will be difficult to refine. If you smelt metal, you must select good ore and remove its impurities to obtain fine iron and pure copper. "Tiangong Kaiwu" says that the copper for casting money must be of the best quality. After several refinements to remove lead and tin miscellaneous, you can cast fine coins. The color is pure and the shape is regular.
The second is the craftsmanship. Proper operation can ensure purity without damage. Taking winemaking as an example, from grain soaking, fermentation to distillation, every step needs to be in harmony. When soaking grain, the water is clear and turbid, and the length of time is particular; when fermenting, the control of temperature and humidity is critical to success or failure; when distilling, the method of heat and condensation cannot be ignored. Only by following the ancient method can we brew a mellow and pure wine without peculiar smell.
Furthermore, the purity of the environment is also necessary. The place where the product is made needs to be protected from dust. If it is in a dirty place, dust and foreign objects will easily enter the product, which will damage its purity. The ancient ink making, in the clean room, uses pine wood to burn smoke, carefully collects it, and then combines it with glue and other substances to produce a good ink with pure ink color and smooth writing.
And in the process, there must be supervision. Every step is carefully reviewed, and if there are signs of impurity, correct the deviation in time. Such as sugar making, observe its color, taste and shape, if the color is strange, adjust the heat and process to make the sugar as pure as ever.
In short, to ensure the purity of the product, the selection of materials, craftsmanship, environment and supervision are all important, all of which are indispensable. Take the ancient method as a mirror and practice in today's business to ensure the purity of the product and high quality.

When storing this item, there are many precautions that need to be treated with caution.
First, pay attention to the ambient temperature and humidity. This item is quite sensitive to temperature and humidity, and overheating or overhumidification may cause its properties to change. If it is in a high temperature environment, it is easy to cause deterioration, just like fresh fruits under the hot summer sun, which will rot instantly; if the humidity is too high, it may also make it damp and moldy, just like wood in a damp corner, which will grow moldy for a long time. Therefore, the storage place should be selected with constant temperature and moderate humidity to ensure the stability of the item.
Second, pay attention to ventilation conditions. Good ventilation can circulate air and disperse moisture and turbidity that may accumulate. If the ventilation is not smooth, turbid gas will accumulate, or it will erode the goods, just like a claustrophobic room, the air is turbid, and it is easy to dye dust and foul gas. Make sure that the storage space is well ventilated, so that the goods can "breathe" fresh air.
Third, avoid mixing with other items. Different items have different properties, mixing or chemical reactions will damage the quality of the goods. If acid and alkali substances cannot be in the same place, otherwise they will interact and cause damage to the goods. According to the characteristics of the goods, they should be stored separately or in categories to prevent mutual interference.
Fourth, pay attention to the influence of light. Some items are not resistant to light, and long-term exposure to sunlight will fade and age. Like a colorful fabric, after long-term sunlight, the color fades and the texture becomes brittle. When storing, you should choose a place that is protected from light, or use a shading material to protect it from light.
Fifth, regular inspection and maintenance. During storage, you need to check the condition of the item regularly. If there is any abnormality, such as moisture or deterioration, take timely measures to remedy it. Just like regularly inspecting the warehouse and finding problems, deal with them immediately to avoid the problem worsening and causing greater losses. In this way, the item can be properly stored and maintained in good condition.

Today, there are those who ask about the price of the city. The prices of various things in the city are different, and the categories are diverse, so it is difficult to generalize.
In terms of all kinds of utensils, if the exquisite porcelain vase is well-made and beautifully decorated, its price may be as high as a thousand gold; while the ordinary pottery urn, used to store grain and store goods, is not worth a few tens of dollars. If it is silk and satin, the best products, the color is smooth and smooth, from the hands of skilled craftsmen, the price can reach hundreds of dollars per horse; coarse cloth linen clothes, the price is quite cheap, or only a few tens of dollars per horse.
As for fruits and vegetables, they vary from time to time. In spring, new vegetables come out, fresh and tender, but the yield is not abundant, and the price is slightly more expensive; in summer, fruits and vegetables are prosperous, with a wide variety, and the price is slightly lower. Such as lychee, produced in Lingnan, if the local price is still flat; however, if transshipped to other places, after long-distance travel, the loss is quite large, and it is not easy to keep fresh, the price is several times that of the place of origin, up to hundreds of dollars a catty. And ordinary vegetables, such as cabbage, radish, etc., may only be a few dollars a catty when harvested.
As for gold, silver, pearl and jade, the price is always high, up to thousands of dollars per tael; next to silver, every two or hundreds of dollars. The price of pearl and jade varies greatly depending on its color, size, and texture. Beautiful jade is warm and flawless, and it is priceless; second-class jade also costs hundreds of dollars. Pearls are round and shiny, and the price is not cheap. Small and dim, the price is slightly lower.
To sum up, the price of the city fluctuates constantly due to changes in the category, texture, season, origin, and supply and demand of things. It ranges from a few dollars to a thousand gold, and it is difficult to determine a fixed range.
