What you are asking about is the application field of Ertan and Sidong. These two are of extraordinary use in many fields.
In terms of water conservancy and irrigation, Ertan and Sidong have significant effects. Ertan Dam cuts across the river water and can store a huge amount of water. The water stored in its reservoir, after rational deployment, can be diverted to vast farmland, providing abundant water sources for crop growth, nourishing 10,000 acres of fertile land, and ensuring a bumper agricultural harvest. The four-hole one can skillfully guide the water flow, so that the irrigation water is evenly distributed in the fields, avoiding uneven drought and flooding in some places, greatly improving irrigation efficiency and ensuring smooth farming.
In the field of flood control, Ertan can be called the mainstay. When a flood strikes, Ertan Reservoir can use its huge storage capacity to stop flood water and reduce the flow of flood peaks. In case of a major flood, Ertan can properly discharge the flood through precise scheduling of flood discharge facilities, reduce downstream flood pressure, protect coastal towns and villages from floods, and ensure the safety of people's lives and property. Although the size of the four holes is inferior to Ertan, in some areas, it can also assist drainage and reduce the damage of waterlogging.
In the field of hydropower generation, Ertan has made outstanding achievements. The water flow rushes down from a height, hitting the turbine and converting it into electricity. With its huge drop and sufficient water volume, Ertan generates considerable power, providing stable power supply for the surrounding area and even the wider area, and strongly supporting industrial production and residential electricity demand. If the four holes are used rationally, they can also use the power of water flow to realize small-scale hydropower generation and supplement energy supply.
In the field of shipping, the wide waters formed by the Ertan Reservoir improve river shipping conditions. Large ships can navigate smoothly in the reservoir area, promote material transportation and trade, and strengthen inter-regional economic exchanges. If the four holes are in a suitable location, they can optimize the flow of waterways, help small ships pass, and activate inland river shipping.
In the field of tourism, the magnificent dam and vast reservoir area of Ertan form a unique landscape that attracts tourists from all over the world. People can enjoy the beauty of the perfect fusion of nature and man-made buildings here. Due to its unique geological features or long history and culture, the Four Caves can also become a unique tourist attraction, promoting the development of local tourism and driving the prosperity of related industries.

There are two canals and four weirs today. What is the market price? This question is related to the value evaluation of water conservancy facilities, and it is necessary to comprehensively consider many factors in order to understand its market price.
The system of water conservancy, the canal, so the water flow, the fields and the soil are irrigated, which is related to the people's livelihood. Weirs, the tools for holding water, are opened and closed on time, and the water flow is insufficient. It is also important for agricultural irrigation.
In terms of its value, the first function. If the two canals and four weirs are located in a place where the fields are widely spread, and the irrigation depends on them to obtain abundance, then the contribution is great, and the price should be high. If the area where it is located has abundant water sources and does not require the power of this weir, or if there is a weir, but it is in disrepair and its function is declining, the price will be lower.
Times and scale and material. The width and narrow of the canal, the size of the weir, the materials used, and the solid stone and wood used, must be more expensive than those who are perishable. And when building, the cost of labor and geometry is also the price. If the construction is fine and the construction is sturdy, it is comparable to those who are not shoddy.
It is also related to the geographical location. It is located in a passageway, which is easy to repair and maintain, and can benefit many farmers, and the price must be high. If a remote place is remote, inaccessible, and difficult to maintain, the price will also be affected by it.
Furthermore, the needs of the times. During the period of the prosperity of farmers and mulberry, the demand for water conservancy is urgent, and the price of this weir may increase due to it; if in a year of famine, the people are not living well, and the farming is abandoned, the price may drop.
To sum up, if you want to know the market price of the second weir and the fourth weir, you should carefully observe its function, scale, material, location, and situation, and weigh all factors before you can estimate its value. However, if you want to get an accurate price, you need to visit the elderly in the middle of the city, the engineers who are well versed in water conservancy, and the people of the city, collect public opinion, and calculate it in detail.

2-%E6%B0%9F-4-%E7%A2%98%E5%90%A1 the hidden parts, they cooperate with each other in many ways. This artifact bears a specific function, so it needs to be stored in a suitable place according to its nature.
First of all, it is a dry place. The tide can easily cause the decay and shape of the object. If it is placed in the tide, the water will invade, the golden one may be raw, and the wooden one is also prone to mildew and decay, and its original appearance will lose its value. Therefore, it must be flooded, the empty room has good circulation, and the dry room is empty, so as to keep it solid.
Furthermore, a safe place is required. If this artifact is extraordinary, it must have its treasures, or exquisite craftsmanship, or profound culture. If placed in a place that is easy to collide with people, it is easy to be damaged. It should be placed in a safe place, where few people are there, and around sharp and heavy objects to prevent accidental collision and damage.
In addition, light also needs to be paid attention to. Intense light, especially ultraviolet light, can cause fading and aging of utensils. It is not only a colorful utensil, but also a metal surface that is damaged. Therefore, avoid exposing utensils to direct light, and can be placed in a corner with windows or dark light.
The best, and the degree of preservation should also be controlled. It is easy to make utensils crack due to cold. Holding the fixed temperature of the phase, such as the room is between fifteen and twenty-five degrees Celsius, can make the utensils in the fixed temperature and extend their storage life. In this way, the 2-%E6%B0%9F-4-%E7%A2%98%E5%90%A1 can be properly preserved, so that it can be preserved for a long time without loss, and it can carry the cultural story behind it.
