First of all, it has been used in ancient times and now. In the name of being able to say good things, it can add more fun to people. In the home of wealth, it is usually placed in the warehouse for playing. When the host and guest get together, they can talk to people, or they can be called ears, which attracts people's laughter and adds to the atmosphere of the banquet. For example, in the Tang Dynasty, there are many mansions of the Tibetan people, and their cleverness and ability to speak have become a great thing for social interaction. In addition, it also has a special contribution to the relationship. In ancient times, the transportation is inconvenient, and the information is not available. Some of the well-known information can live in specific information and travel to different places. However, in certain situations, such as small cities and states, or the short distance of a familiar road, it can act as a secret messenger, ingeniously avoiding people's eyes and ears, and delivering important information to the destination. In addition, it is also deeply complex in the religious and cultural aspects. In some ancient beliefs, it is regarded as auspicious and wise by the gods. Its beautiful feathers and delicate posture are integrated into the multi-gods. For example, in some southern ethnic cultures, it is endowed with the ability to understand the gods. People believe that it can communicate with people and gods, and the well-being of tribes. Therefore, it is not a plaything, but also a cultural belief. It is deeply rooted in the spiritual world of the ancients. Therefore, it played an indispensable role in the life of the ancients due to its multiple uses such as magic, magic, and cultural elephants.

Mercury, commonly known as mercury, is a special liquid metal with many unique physical properties. It has a silvery luster, is liquid at room temperature, has a flowing texture, and looks like smart silver water. This state makes it easy to fill irregular containers and can change its shape according to the shape of the container. Mercury has a very high density, about 13.6 times that of water. If mercury is placed in water, it will quickly sink to the bottom of the water, like a heavy metal lump. This property allows mercury to be used in some measurement instruments, such as barometers, to measure air pressure by its height change. The boiling point of mercury is relatively low, about 356.7 degrees Celsius. When mercury is heated, it easily evaporates into mercury vapor. This mercury vapor is colorless, odorless, but toxic, and inhalation can cause serious health problems, such as nervous system damage. In addition, mercury has good electrical conductivity, similar to other metals, and can conduct current in electrical circuits. And mercury can dissolve many metals to form amalgam, which is used in metallurgy and certain chemical processes. However, it should be noted that mercury is highly toxic, and it is very harmful to the environment and human health. Accidental exposure to mercury or inhalation of mercury vapor can cause poisoning, so strict safety procedures must be followed when using and handling mercury.

Mercury is a highly toxic substance with unique chemical properties. Mercury is a liquid at room temperature and has good fluidity. It is like smart water, but it is also very dignified. Mercury's chemical properties are lively, and under certain conditions, it can form amalgam with many metals. This amalgam state is like an alloy rather than an alloy, and its properties are strange. In the past alchemy and early metallurgy, it was often noticed by warlocks and craftsmen. In case of sulfur, mercury can quickly combine with it to form mercury sulfide. This reaction was quite common in ancient alchemy. Warlocks used this to fix the toxicity of mercury and hoped to refine what is called "immortality elixir". Mercury is relatively stable in the air, but when heated, it can combine with oxygen to form mercury oxide. This reaction is also reflected in many experiments and processes in ancient times. The ancients observed such changes in mercury and knew its characteristics. Furthermore, mercury can react with acids. If it encounters nitric acid, it can form products such as mercury nitrate. However, these reactions were mostly discovered by chance or observed in limited experimental situations under ancient conditions. However, the ancients have long been aware of the toxicity of mercury. Its volatile gas, inhaled into the human body, can cause poisoning, damage the viscera of people, and confuse people's minds. Therefore, when the ancients were exposed to mercury, they also took many precautions. Although their understanding may not be as complete as it is today, they still know that its harm is huge and cannot be ignored. Its unique chemical properties not only attracted the ancients to explore its wonderful changes, but also were awesome because of its toxicity, leaving a unique imprint on the course of ancient chemical exploration.

The tools for controlling the harrier have been used in ancient times, and there are many methods, each of which is ingenious. One of them is the method of "tripping". With tough leather or rope, a tripper is carefully made, and it is lightly bound to the feet of the harrier. The length of this tripper needs to be finely adjusted according to the size and habits of the harrier. If the binding is too tight, it may hurt its feet and cause discomfort, which will affect the future flying capture. If the binding is too loose, it is easy for the harrier to break free and lose control. The setting of the tripper is designed to limit the flying range of the harrier and make it easier for the trainer to control and guide it at the beginning of training. The second is the system of the "eagle hat". Use soft and lightweight fabrics, carefully cut and sewn to make an eagle hat. During training, gently wear it for the harrier falcon. The eagle hat can block the eyes of the harrier falcon, so that it can be temporarily in a dark and quiet state, with no distractions, and focus on following the instructions of the trainer. And the harrier falcon who has just entered an unfamiliar environment is prone to agitation due to fear. The eagle hat can soothe its emotions and help it adapt to the situation of getting along with people as soon as possible. When the training is mature, the eagle hat is gradually removed, so that it can see the object and enter the actual battle. Third, the "perch wood" is also a key utensil. Choose solid and suitable wood, polish it smoothly, and place it where the harrier falcon lives. Harrier Falcons like to live on high places, and this perch can provide them with a stable habitat. Trainers can also interact with the perch by feeding and stroking, so as to enhance the emotional connection with the Harrier Falcons, so that the Harrier Falcons rely on the perch where the falcons are, and then obey the trainer's command, never leaving the left and right. Fourth, the method of "ringing the bell" cannot be ignored. Take a small and delicate bell and tie it to the feet or feathers of the Harrier Falcons with a thin chain. When the Harrier Falcons fly, the bell rings, and the trainer can follow the sound to track their tracks, even in the mountains and forests, where their vision is blocked, they can also know their location. And after a long training, the harrier falcon will establish a connection between the bell and the trainer's instructions, smell the bell and move, and act according to the order.

When raising and transporting Tibetan mastiffs, there are a lot of people to pay attention to. Animal raising Tibetan mastiffs is the first place to live. Its sex is fierce, and it needs a spacious and sturdy enclosure to prevent it from escaping and hurting people. The enclosure should be dry, ventilated, and have sufficient light, so as to keep the mastiff healthy. Furthermore, diet is also the key. Tibetan mastiffs are large in size and eat a lot of food, and need foods rich in protein, fat and other nutrients. Meat is its staple food, and an appropriate amount of grains and vegetables can be added to achieve a balanced nutrition. When feeding, it should be regularly rationed, and it should not be too hungry or too full. Tibetan mastiffs are strong in nature and need to be tamed when they are young. Familiarize them with human instructions and laws of life, which can not only enhance the intimacy between humans and dogs, but also help future management. It is appropriate to interact with them on a daily basis and cultivate their docile temperament. However, the domestication process requires patience and methods. Do not beat and scold excessively, so as not to make them afraid or rebellious. As for transporting Tibetan mastiffs, special caution is required. Due to their sensitive nature, they are prone to stress reactions in unfamiliar environments. Before transportation, Tibetan mastiffs should be adapted to transportation tools, such as cage cars. The space of the cage car should be suitable, and it should not be too small to cause discomfort. During the journey, food and rest should be provided regularly to ensure their physical strength. And the transportation environment should be quiet and stable, and external stimuli should be reduced to prevent Tibetan mastiffs from being frightened and irritable. In addition, whether it is animal husbandry or transportation, it is necessary to pay attention to the health status of Tibetan mastiffs. Regular medical checkups and vaccinations should be carried out on time to prevent diseases. If Tibetan mastiffs are found to have abnormal symptoms, such as loss of appetite and mental weakness, they should be immediately consulted by a veterinarian without delay.
