After walking along the street for a long time, the crowds gradually became sparse and the art festival was coming to an end.
Qin He said: "We need to find something that can purify the water."
Kuang Yan said: "What's wrong? I suddenly thought of this."
Kuang Yan said: "For the same reason, I just thought of it. I need to find something that can purify the soul."
Qin He said: "What is it?"
Kuang Yan said: "The first thing that comes to mind is friends."
Purifying water and purifying the mind both involve removing impurities and harmful substances to achieve a state of purity and cleanliness. Here are some similarities between them.
For example, cleaning up pollution. The process of purifying water involves removing impurities, harmful substances, and bacteria from the water to make it purer and safer. Similarly, mind purification works by clearing away negative emotions such as anger, sadness, and worry to achieve a clean and balanced mind. Purified water helps eliminate potential germs and contaminants, providing a healthy drinking water source. Purifying the mind eliminates negative emotions and thought patterns, bringing about inner peace and happiness.
For example, improving quality. Purifying water improves its quality and makes it more suitable for drinking and use. Purifying the mind can improve inner qualities, such as kindness, tolerance and peace of mind, so that oneself can be more harmonious and balanced, and treat others more enthusiastically. Purifying water helps improve the environment, reduce water pollution and protect the sustainability of ecosystems. Purifying the mind improves the personal and interpersonal environment, reduces the presence of conflict and negative energy, and promotes harmony and balance.
Purified water requires regular maintenance and monitoring to ensure continued purity and cleanliness. Purifying the mind also requires ongoing self-reflection, emotional management, and spiritual practice to maintain inner purity and balance.
Kuang Yan said: "We have not yet reached the state of not causing dust. We can only 'wipe it from time to time so as not to cause dust.'"
Hao Xiu said that some aquatic plants can remove pollutants and toxic substances from the water. I heard that there is this kind of plant in the lake area south of Sencheng.
The roots of this aquatic plant can absorb dissolved pollutants in the water, such as heavy metal ions, organic matter, etc. Plant roots have rich surface area and porous structure, which can expand the absorption range and increase the contact area of pollutants, thus improving the adsorption efficiency. After these pollutants are absorbed by plant roots, they will enter the stems, leaves and other parts of the plant. There are many tiny bristles, gums and other substances on its stems, leaves and other parts. These substances can adsorb suspended matter, particulate matter and other pollutants in the water, forming clumps or sediments, causing them to settle to the bottom of the water or be carried away by the water flow. At the same time, the stems and leaves of plants can also concentrate pollutants in the water to the surface of the leaves through transpiration, further accelerating their removal.
Its stems, leaves and other parts are also rich in various enzymes and microorganisms, which can decompose organic matter in the water. Some enzymes and microorganisms degrade organic matter into inorganic matter, such as carbon dioxide, water, etc. through metabolism, thereby removing organic pollutants from the water.
Qin He called Kuang Yan and said, "I want to look for purifying plants in the lake area south of Sencheng. I heard from my friends that there are some there."
Kuang Yan said: "Okay, then I'm going to get off the boat and other things."
Kuang Yan, Qin He, and Xia Yueling prepared to row a boat into the lake to look for aquatic plants. First, they prepared the necessary tools, including paddles, fishing nets, magnifying glasses, etc., to better observe and collect aquatic plants. We also rented a boat in advance. There is no powered propeller, so you get a paddle and rely on human power to paddle it.
Qin He said: "This time it mainly depends on your efforts."
Kuang Yan said: "It's okay, I'm happy to contribute." It's good to climb mountains and row boats together.
Once they arrived at the lake, they carefully pushed the rented boat into the water. Kuang Yan picked up the paddle and started rowing the boat, letting the boat slowly sail towards the center of the lake. At the same time, Qin He and Xia Yueling sat on the boat and carefully observed the waters around the lake with telescopes.
Kuang Yan, Qin He and Xia Yueling came to a maze-like lake with clear blue water and surrounded by green trees and dense bushes. They desperately needed to find a waterway to continue their journey.
Kuang Yan was a brave and smart man. He looked towards the lake and observed the water carefully. He found some small green plants floating on the surface of the lake. These plants looked like submersed plants. Kuang Yan realized that this might be a clue that would lead them to the waterway, so he decided to continue exploring along the lake.
Qin He and Xia Yueling carefully observed the plants on the surface of the lake. Qin He noticed that the shapes and colors of these plants were so beautiful, while Xia Yueling noticed that these plants seemed rare and should have some special function.
After a while, Kuang Yan told Qin He and Xia Yueling with a face full of joy that they found a creek ahead that seemed to be covered with aquatic plants. Kuang Yan explained that he kept walking along the silk-leaf cabbage and finally discovered an area covered with lotus leaves. Through observation, he determined that these plants were pointing towards the stream, and decided to follow their growth pattern and move forward.
Qin He and Xia Yueling were excited about Kuang Yan's discovery. Together they passed through the area covered with lotus leaves and finally came to a clear stream.
They pay attention to whether there are traces of aquatic plants on the lake, such as duckweed, water lilies, etc. Once signs of aquatic plants are found, Xia Yueling will immediately point them out and tell Kuang Yan to change the direction of the boat and try to get as close as possible to the area where these aquatic plants are located.
When the boat got close to the aquatic plants, Kuangyan stopped the oars and fixed the boat in place next to the tree trunk to keep the boat stable. Then, Qin He and Xia Yueling will use fishing nets to carefully pick up aquatic plants and put them into containers on the boat.
They observed the appearance characteristics of the collected aquatic plants, such as leaf shape, color, texture, etc., as well as the growth status of the root system. Qin He and Xia Yueling also used magnifying glasses to carefully observe the details of aquatic plants, such as whether there are hairs and stomata on the surface of the plants.
In the process of collecting aquatic plants, they paid attention to whether there were other organisms living in symbiosis with aquatic plants, such as small fish, snail lizards, etc. If they find organisms living in symbiosis with aquatic plants, they will also collect them.
In the process of searching for aquatic plants in the lake, Kuang Yan, Qin He, and Xia Yueling observed patiently and carefully, rowing to different areas to search for different types of aquatic plants. This also helps to understand the ecological environment, water quality conditions and distribution of aquatic plants in the lake.
Next to the stream, they felt a cool breeze and heard the gentle sound of flowing water. They were relieved that they had finally found a waterway and could continue their journey.
