The four rivers, rivers, huai, and the sea are also. These four waters are the great waters in the world, whose source is flowing, and the profit is made, and they are used for people's livelihood and the sea.
The river is also the source of the river, which originates in the border of Tubo, and the flow is a thousand miles and enters the sea. Its flow is vast, and the waves are the school of water. Along the river, the land is fertile and fertile, the boat is Tongli, the business is not easy, the humanities are collected, and the weight of the world is the weight of the world.
The river is also the source of the river, which originates in the north of the river, the rock and the sea. Its water is, good silt and good migration, but the benefits of irrigation also reach the province. Those who governed the river in ancient times, with great mental effort, to clear the water and prevent it, because of the people's livelihood.
The Huai River is also the source of the Tongbai Mountain, and it flows into the sea. Its location is located between the river and the river, and it is important to the north and south. The benefits of the Huai River lie in the irrigation system, and its watershed is also known as the "rice of the sea".
The water of the Huai River is also the source of the Wangwu Mountain, in the flowing area, to the Henan Province, and the water of the river flows into the sea. The water is not as grand as the river and the river, but its clear flow, the resistance but not the water, its nature is clear, and it is important to the ancients.
The key to the four principles is to irrigate the fields and nourish the food, so that the people can have enough food and clothing; it is also convenient for boats and transportation, to promote business and prosperity; and it is also important for water conservancy, flood control and drainage, and to ensure the safety of the people. Therefore, all generations have attached great importance to the governance of the four principles, so as to ensure their long-term benefits and well-being.

Of the four rivers, each has its own. The river is the largest, its nature is majestic and vast, and it can run endlessly, the vast and vast, and it is like the heroic power of the sky. It can be used to sail boats, irrigate the fertile fields in the river, and nourish the life. However, its anger can also be surging, causing floods.
The river is the ancient river, its water is running and rushing, the sediment content is huge, and the water is fierce. The river meanders for thousands of times, giving birth to ancient civilizations, but it is not turned into a river, and the embankment is overflowing. It is often used in fields, people and animals, and one side is suffering.
Those who are in the river, the flow of the river is flat, but the water system is not intersected, and there are many lakes. The land of Huaishui is full of water, and the things are full of water. However, due to the terrain and water system, every time there is a rainstorm, it is also easy to cause water to form, and the flood hazard will remain.

The water is sweet and mellow, and the water is soft. The ancient water flows into the sea, and the river channel has been damaged. However, its clear nature has not been changed. The power of irrigation also benefits the coast, nourishing the things, silently and making a contribution to the world.
The four kinds of water have their own characteristics, or strong, or fierce, or flat, or gentle. Its goodness, education and health, and commerce; its safety, causing harm to the people. People respect and fear it, and use it to avoid harm and benefit, and to coexist with nature and nature.

The four rivers of water each have their own nature. The river is surging, its nature is strong, and it is majestic. It often carries sediment and sand, like an uninhibited dragon, crashing into the earth, shaping the landscape of mountains and rivers, and nourishing the fertile soil on both sides.
The river is long, its nature is soothing and deep, accommodating hundreds of rivers, vast soup and soup, giving birth to countless creatures, its flow is also continuous, and its accumulation is also profound. It provides a passage for the passage of ships and carries many civilizations.
Although the Huai water is also surging, its nature is relatively peaceful, its basin is vast, and there are many moist lands, nourishing one side of the people, irrigating the fields, and making farmers prosperous.
Jishui is unique. Although it is one of the four blasphemies, it often flows underground, sometimes disappears, and sometimes comes back. Its clear quality, like the virtue of a gentleman, is hidden but not exposed, but also contains far-reaching.
The river is strong and uninhibited; the river is deep and accommodating; the Huai level is peaceful and nourishes all things; the water is clear and impermanent. These four blasphemous waters, with different natures, are all masterpieces of creation in heaven and earth. On the earth of Huaxia, they deduce endless legends, lay a deep foundation for the growth of all things and the reproduction of civilization, and nourish the prosperity of China for thousands of generations.

The book "Tiangong Kaiwu" says: "Where bamboo paper is made, it goes out of the south, but Fujian Province specializes in its prosperity. When the bamboo shoots are born, look at the depth of the mountain nest, and the bamboo is fed with those who will grow branches and leaves. During the festival, the mango seeds are cut down from the mountains. Cut off five or seven feet long, and open a pond on this mountain, fill it with water and drift it. When the pond water is afraid of drying up, use bamboo soda to guide it, and continue to flow into the water. Soak it for a hundred days, add work to wash with mallets, and wash away the coarse shells and green skins. Among them, the bamboo is shaped like ramie, and it is pulped with a good lime juice, boiled under the bucket, and the fire is at the rate of eight days and eight nights." Although this is the method of making bamboo paper, the principle of all things may be the same.
The method of making a broom also has many details. First, the selection of materials is essential. It is necessary to choose tough and moderate-length branches and stems, such as sorghum ears, millet ears, etc., both of which are common and good materials. Sorghum ears are solid and durable, and the broom is powerful; millet ears are soft and light, suitable for sweeping the subtleties. Second, organize the materials. Remove sundries from the selected spike stems, straighten the organization, and make the length orderly, which is convenient for subsequent production. Third, bundle and form. With tough ropes, tightly wrap the roots of the spike stems, and bundle them layer by layer to ensure that they are tight and not loose. The method of bundling is related to the service life of the broom. If the bundling is not strong, it is easy to loose when used. Fourth, trim and improve. After forming, trim the shape of the broom to remove the overly long or uneven parts, so that its appearance is neat and easy to use.
The method of making a broom, although not as complicated and exquisite as the skills described in Tiangong Kaiwu, still needs to be done with care to become a usable tool and bring convenience to daily cleaning.
