The first is the benefit of irrigation. There are many fields here, and the water of the three cities can be used to nourish it. The key to the matter is the root of water. Every time it is cultivated, water is diverted to irrigate the fields, so that the crops can be cultivated, and there is no harvest. Gu Yun: "Water conservancy is the key to prosperity." This water is the source of irrigation, thousands of miles of fertile fields, and the people's food, all of which are here.
The second is the convenience of the boat. The three waterways are steep and the water of the barren water is passed through them, forming a natural channel. Boats and boats go to the river, passing through Ba, Shu, and Chu. Business is easy, so it is easy to do. It is not the local specialties, such as tea, rice, etc., that can be exported; other places can also be imported. The benefits of water promote the exchange of four sides, and the prosperity of the city.
Third, educate the people. The residents of the riverside have lived by the water for generations. The water is rich, and it can be used for fishing and living. And the water can be used, and people and animals can be used. The surrounding water and soil are fertile, and the grass and trees are lush. Livestock and gathering provide convenience. People gather by the water to form villages and cities, develop culture, and multiply for generations.
Fourth, wait for the time to come. The water of the great river has the power of the week. In summer, the fire is hot, and the water is steaming, which can reduce the temperature and increase the temperature; in winter, it is cold, and the water is stable, which can be slightly cold. So that this environment is not at the end of the world, and is beneficial to the lives of the people.
Where this is the case, the water of the three cities is of paramount importance in many aspects such as transportation, people's livelihood, and climate. It is used to nourish the land and people.

The river in Yiling County of the Three Gorges is particularly impressive in its physical properties. Its water color is clear, often in a transparent state, and the sun shines brightly, just like a long river paved with jade. Looking at its water flow, it is slow and urgent. In the open place, the water waves are not active, like the flat of a mirror, you can learn from all things; in the narrow valley, it is rushing and roaring, and the sound of the waves is shocking to the ears. Its momentum is like a galloping horse, unstoppable.
Furthermore, its water temperature also has characteristics. In the four seasons, the spring and summer are warm, the river water heats up slightly, and it still feels cool to the touch; the autumn and winter are cold, and the river water cools slowly, so the winter is not extremely cold. This characteristic has a huge impact on the surrounding ecology, enabling many aquatic organisms to multiply and inhabit here.
As for the density of river water, it is similar to that of ordinary rivers, but there may be local or subtle differences due to the difference in mineral content in the basin. Its buoyancy is moderate, and boats travel on it, stable but not swaying, which is conducive to boat transportation.
And the power of this river's water flow is quite considerable. The rushing water contains huge kinetic energy, which can provide hydraulic convenience to the surrounding areas. For example, in ancient times, water-powered mills and other facilities operated by the power of river water, saving manpower and having significant effect.
And looking at its solubility, the water dissolves an appropriate amount of oxygen and nutrients to nourish aquatic organisms. Fish swim during it, and aquatic plants swaying, all rely on this good dissolving environment. With its unique physical properties, this river nourishes the land and breeds thousands of vitality, which is of vital significance to the local people's livelihood and ecology.

The chemical properties of the water in the Three Gorges can be studied. This water originates from the Three Gorges and is located between mountains and rivers. It contains many substances and its properties are complex.
Water is often colorless and transparent, with a light taste and no smell, which is a sign of its appearance. In terms of physical properties, the water in the Three Gorges is liquid at room temperature and pressure, with a boiling point of 100 degrees and a freezing point of zero degrees.
As for its chemical properties, the first consideration is pH. The pH value of this water is often close to neutral, but it may be slightly biased due to the surrounding environment. The water contains trace mineral ions, such as calcium ions, magnesium ions, etc. This plasma makes the water have a certain hardness.
Water also dissolves some gases, such as oxygen and carbon dioxide. The dissolution of oxygen makes the water fertile for aquatic organisms to breathe; carbon dioxide forms a carbonic acid balance in the water, which has the effect of adjusting the pH of the water.
Furthermore, the water of the Three Gorges has the chemical activity of ordinary water. Water can react with many substances, such as metal oxides to form bases; it reacts with non-metallic oxides to form acids. In case of active metals, such as sodium, potassium, etc., it can react violently to release hydrogen.
In addition, microorganisms in water also affect the chemical properties of water. The metabolic activities of microorganisms can change the composition and content of substances in water, such as decomposing organic matter and releasing nutrients, which in turn affects the chemical balance of water.
Overall, the chemical properties of the water in the Three Gorges are influenced by many factors such as geographical environment, contained substances and microorganisms, showing a unique and complex state, which plays an important role in the surrounding ecology and environment.

There are quite a few ways to make Sanxiang Yulu tea. The first is the method of picking. When it is spring, when the morning dew is not yet weeping, choose the tender buds and leaves of the tea tree. The buds need to be full, and it is better to have one bud and one leaf at the beginning, so as to ensure the freshness and mellow taste of the tea leaves.
The second is the technique of spreading and drying. The picked fresh leaves are placed in a clean and ventilated place and thinly spread on them. Make the fresh leaves naturally emit water vapor, and can make their internal components moderate transformation. When spreading and drying, pay attention to the change of temperature and humidity, and do not make them too dry or too wet. After a few times, until the leaf color turns dark and the aroma is slightly displayed, it is moderate.
Furthermore, it is the method of killing green. It is appropriate to fry and kill green in a pot, heat the pot to a suitable temperature, and put the fresh leaves that have been dried into the pot. When frying, you need to be skilled, stir fry quickly, so that the leaves are heated evenly, and kill enzymes to keep green, so as to stop their fermentation. The heat temperature needs to be moderate. If it is too high, the leaves will be easy to burn, and if it is too low, the killing will not be transparent, causing the tea leaves to have green gas.
After that is the art of kneading and twisting. After killing the tea leaves, place them in a kneading and twisting utensil while they are hot. When kneading, the force needs to be uniform, first light and then heavy, so that the tea cells are broken and the tea juice overflows, so The degree of kneading and twisting is based on the tea leaves forming strips and part of the tea juice overflowing.
There is also a method of drying. After kneading and twisting, the tea leaves can be dried or stir-fried. For dryers, bake them at a suitable temperature to reduce the water content of the tea leaves to a moderate level. When stir-frying, you need to stir-fry them slowly over a slow fire to make the water of the tea leaves dissipate and give full play to the aroma. During the drying process, you need to turn them often to prevent them from burning. Only by using this method can you get high-quality Sanxiang Yulu tea, which has a high aroma and a unique flavor.

When picking this inkstone, you should carefully choose good materials. The quality of the stone is warm and delicate, and the texture is beautiful, so it is the best choice. If the quality of the stone is rough and messy, it is difficult to become a good product. Careless mining, or causing stone injuries and damaging its texture, has a great impact on the quality of the inkstone.
When making inkstones, the craftsman's skills are crucial.
The shape of the inkstone, whether simple and elegant, or exquisite and chic, depends on the ingenuity and skill of the craftsman. The carving lines must be smooth and natural, and should not be stiff and stiff; the shape should be based on the shape and quality of the stone, and follow the trend to highlight the beauty of the stone. It must not be artificial or damage its charm.
When using inkstone, there are also many details. When grinding ink, the amount of water needs to be appropriate. If there is less water, the ink will be thick, and the writing will be stagnant; if there is more water, the ink will be light, and the handwriting will be dull. And clean water must be used. If the water contains impurities, it will stain the inkstone and affect the quality of the ink. The ink grinding action should be slow and even, and it should not be done too hastily to avoid hurting the inkstone. After use, when the inkstone is washed in time, rinse it slowly with water to remove the ink stains, and do not leave ink on the inkstone, otherwise the ink stains will dry up, which will not only damage the appearance of the inkstone, but also affect the next use.
When storing inkstones, the choice of environment should not be ignored. It should be placed in a cool and dry place, away from direct sunlight and damp places. If the sun shines for a long time, the inkstone is easy to dry and crack; if it is too humid, it is prone to mildew spots and damage its appearance. If it is not used for a long time, you can apply a thin wax to protect the quality of the stone and make it moist forever.
All these kinds of things are the key to the use of the inkstone in Sanxiang Luxi. Users can pay attention to this, so that they can get their true
