And in traditional folk activities, the image of sea clams is often found in various handicrafts, paintings, etc., carrying the people's yearning and expectation for a better life, and inheriting the unique cultural memory of the region.
To sum up, "1-Jiang-4-Sea clams", whether eaten as delicious, used as good medicine, or as a symbol of culture, have shown value that cannot be ignored, and are of great use to people's livelihood.

Water, that is, mercury, is a common element of gold. Its physical properties are special.
First of all, under the constant temperature and force, water is liquid, which is its most characteristic. Many metals are often different in the world. Water is like a flowing river, smooth and smooth. Its flow is good, and it can be easily stretched and extended on a plane.
In addition, its color and light, the color of water is white, shining, like the moonlight, the reflected light is very bright, so it shines brightly under the light, attracting people's attention.
And density, the density of water is large, 13.6 grams/cubic centimeter, and the weight of many ordinary things is heavy. If an object is thrown into water, if its density is less than that of water, it can float on it. This property also makes water useful in certain quantities and fractions.
The quality of water cannot be ignored either. Its good performance makes it possible for water to flow in it, so it is often used in fields such as appliances and watches. However, in the same way, its performance is not good in terms of performance, and it is slightly more colorful than that of some good metals.
In addition, the melting temperature of water is very low, -38.87 ° C, so it can still maintain liquid performance in a low temperature environment. And its boiling temperature is 356.6 ° C, when the boiling temperature rises to the boiling temperature, the water will quickly vaporize and melt from the liquid.
In addition, the physical properties of water make it useful in different technologies and fields. However, due to its toxicity, it should be used with caution.

Lead is one of the hardware. It is soft and heavy in nature, blue and gray in color, and often appears in ore veins. The chemical properties of lead are fascinating to study.
Lead has strong corrosion resistance. In normal environments, lead gradually reacts with oxygen in the air, forming a thin layer of lead oxide on the surface. This layer of oxide acts as a strong shield, which can prevent further oxidation of lead, so lead can be stored outside for a long time and less damaged. For example, in the past, many roof drainage tanks were mostly made of lead. After years of wind and rain, they could still maintain their shape and use it to their fullest extent, all relying on this anti-corrosion property.
The chemical activity of lead is relatively less active. In the order of metal activity, after lead occupies hydrogen, it is difficult for lead to react with dilute acids such as dilute hydrochloric acid and dilute sulfuric acid at room temperature to generate hydrogen gas. When encountering strong oxidizing acids, such as nitric acid, lead will chemically react with it. If it encounters dilute nitric acid, lead nitrate will be formed, and it will be accompanied by the escape of nitric oxide gas. This reaction shows that lead can chemically change with acids under specific conditions.
Furthermore, lead can combine with many non-metallic elements. When encountering sulfur, lead easily reacts with sulfur to form lead sulfide. Lead sulfide is black in color and is commonly found in some forms of lead ore. This combination reaction occurs from time to time during the formation of minerals in nature, and has a deep impact on the morphology and distribution of lead ore.
Also, lead compounds have different properties. For example, lead hydroxide, which is amphoteric, can not only react with acids to form corresponding lead salts and water, but also react with strong bases to form lead salts and water. This property makes lead hydroxide have its unique uses in the chemical industry and scientific research fields.
The chemical properties of lead have far-reaching implications in many fields. In the metallurgical industry, lead's corrosion resistance and relatively stable chemical properties make it an important component of many alloys; in chemical production, lead compounds are widely used in pigments, batteries and other industries. However, lead and its compounds are highly toxic and pose great harm to human health and the environment. When used, one must be cautious.

To prepare 1-fen-4-bromonaphthalene, the method is as follows:
Take the naphthalene as the base first, and the naphthalene has a dicyclic aromatic compound. Use bromine as the brominating agent, and iron or iron salt as the catalyst. Place the naphthalene in a suitable reactor, and pass dry gas inside to prevent the disturbance of impurities. Slowly add bromine solution, and add a little iron filings at the same time to promote the speed of the reaction.
The reaction of bromine and naphthalene should be controlled at its temperature. At the beginning, the reaction is slightly slow and gradually intense. Use water or other cooling methods to stabilize its temperature to prevent it from overheating and causing side reactions. On the capillary ring, bromine is easily added to the α position. However, if the temperature is too high or the time is too long, there is also the possibility of substitution of the β position. Therefore, temperature control is necessary.
After the reaction is completed, the product is mixed in the system. Wash with water first, except for the untreated bromine and iron salts. Bromine water is soluble and can be removed. Then extract it with an organic solvent, such as ether, dichloromethane, etc., so that the product is concentrated in the organic phase.
The organic phase is dried with anhydrous sodium sulfate or magnesium sulfate to absorb its moisture. After distillation, the organic solvent is first removed, and then the temperature is controlled to steam out 1-fen-4-bromonaphthalene. Because the boiling point of the product is fixed, according to its physical properties, a pure product can be obtained
The method of making this product focuses on temperature control, anti-impurities, and refining steps. If one step is wrong, the product will be impure and the yield will be low, so it needs to be done carefully.

1-Jiang-4-Sea sharks should be careful both when they are hidden and when they are lost. If you hide them, you should first pay attention to the place where they are located. You need to choose a cool, dry and well-ventilated place to prevent them from spoiling. The quality of the sea sharks is easy to break in case of damp and heat, so the place you hide must meet these conditions before they can last for a long time.
Furthermore, you should also pay attention to the utensils you hide. It is better to use porcelain urns or wooden boxes, because they can slow down the change of temperature and humidity and protect the quality of the sea sharks. Do not use rusty iron tools, for fear that rust will stain them and damage their original nature.
As for losing them, it is necessary to have a stable path. The chariots and horses that are transported are selected to be solid and stable, in order to prevent the sea sharks from being damaged due to turbulence. And during the journey, you need to check when you need to check, and if the road conditions are not good, you should be more cautious and slow.
Also, pay attention to the season of losing. It is advisable to avoid the days of extreme heat and cold. In the heat, the sea sharks are perishable, and in the severe cold, they are afraid of freezing. In spring and autumn, the climate is mild, which is a good time to lose.
In addition, everyone who loses should be aware of their physical properties and handle them with caution. Do not treat them rudely, or cause them to be injured. All these are things that should be paid attention to by the Tibetan and the sea sharks, and must not be ignored, so as to keep the sea sharks intact and
