Dolphins are aquatic mammals closely related to whales and porpoises, which evolved in the Miocene about 10 million years ago, and lived widely in shallow seas near the continental shelf, occasionally in freshwater. The various species of dolphins range in length from 1.2 to 9.5 meters and weigh from 40 kg to 10 tons, and feed mainly on fish and mollusks. There are 18 species of dolphins known along the coast of China.

Dolphins have a friendly appearance and a playful personality, and have always been very popular in human culture.

Some dolphins are highly social species, living in large groups (sometimes over 100,000 individuals), exhibiting many interesting group behaviors and multiple ways of cooperation between members, one example of which is that these groups sometimes attack sharks and kill them by impact. Members also work together to help injured or sick individuals. Pods of dolphins often follow the boats as they ride the waves, sometimes acrobatically taking to the skies.

There are many legends about dolphins, and some of them are true. For example, the Greek historian Rotustu recorded the incredible story of Arion, a famous lyric poet and musician who lived on the island of Leesburg in the 6th century B.C., and after a tour in Italy, he was about to return to Corintton with a large amount of money. At that time, Arion begged him to sing another song, and the sailors agreed. Who knows, his beautiful singing voice has attracted countless sea monsters! After he was thrown into the sea, one of them carried him all the way to the shore. This mysterious animal is the famous dolphin.

Even in modern times, dolphin rescues have occurred repeatedly, such as in the 1949 publication of the journal Natural History. It was published that a lawyer's wife in Florida was drowned in the sea and fell unconscious, just when life and death were at stake. A nearby dolphin pushed her onto the beach.

Not only can dolphins save people in times of danger, but they are also talented performers. It can perform many wonderful performances, such as drilling hoops, playing basketball, "shaking hands" and "singing", etc., and more importantly, the dolphin has its own "signal" call, which allows its companions to know who it is and where it is, so that they can communicate with each other.

However, because human beings unthinkingly dump all kinds of household waste, industrial wastewater, as well as all kinds of pesticide pollution and oilfield waste into the ocean and rivers. The once clear ocean has become muddy, and major accidents such as oil spills have further deteriorated the marine environment. In densely populated rivers and rivers, eutrophication and heavy metal pollution have threatened the living environment of aquatic organisms, and the proliferation of toxic seaweeds has also made the waters here dangerous. Even at the top of the food chain, dolphins are not immune, with severe damage to their reproductive and immune systems and a vastly increased mortality rate.

Li Yufei: They didn't expect to see dolphins here. As soon as you see these spirits of the sea. Li Yufei couldn't help but think of the stories of man and nature that he had seen before.

In fact, dolphins can be seen in many aquariums nowaries, and humans often let them perform, which is very cute and popular. In fact, the reason why Li Yufei and the others took this private yacht is also inseparable from these guys, after all, the owner of the ship is soliciting business. But you may see dolphins halfway through.

I didn't expect their luck to be good, but now I really see it. See them leaping out of the sea. Under the light of the setting sun, there is so much beauty. Each of their jumps caused the women and men on the ship to scream.

I don't know if the dolphin was born close to people or what. If it were other animals, they would have been scared away when they heard the screams of humans, but they were different, the more Sun Kexin screamed, the more they were excited, as if they thought Sun Kexin and they were playing a game with them, so they danced there more and more frequently.

There were even some bold guys who ran to Li Yufei and jumped not far from their boat, and then the naughty little guy would gently swing their tails, so some water droplets hit Li Yufei directly at them, causing a burst of screams again. Luckily, it's summer, and if it's winter, it won't make people catch a cold.

But it seems that there is no winter here in Hainan, compared to the goose feather snow in the northern winter, even in winter, the temperature is not lower than 10, and even a little sun can reach more than 20 degrees.

Li Yufei saw that those dolphins were not afraid of people at all, and he knew that these guys must have been in frequent contact with these cruise ships and had long been accustomed to their existence, otherwise, they would not have been so close.

However, good time usually passes quickly, and in less than half an hour, Li Yufei and their boat finally drove away. After all, the shipowner still has to do business. At this time, it was almost dark in Sanya, and he was afraid of danger if he put it in the evening. Although Sun Kexin and the others were very reluctant to those dolphins, they had no other way at this time, so they had to reluctantly look back at some of the little guys who were still following behind.

But soon, they all heard the big dolphins screaming like babies, and the little ones went back.

In fact, these dolphins are like passers-by to Li Yufei and them, and all they left behind were some photos. Whether or not they'll see them next time is another matter.

Li Yufei didn't care too much, the rest of the trip was much more monotonous, but when he saw those dolphins in the middle, Li Yufei and all of them were still very satisfied. Although the money is a little expensive, those who can sit on this really don't care about that little money.

By the time their ship docked in Sanya, it was already more than seven o'clock in the evening, and the sun in the sky had just set at this time, but the sky was still very bright, and even the fire-like sunset could be seen.

"It's getting late, let's find a place to stay." Li Yufei pulled Sun Kexin to a taxi. Of course, Sun Kexin will not object.

In Hainan, it is still very easy to find a hotel, there is not much here, but the hotel is definitely the most, and even Li Yufei felt that he had not sat for five minutes, so the driver let them get off.

The driver took them to a hotel with a sea view, and Li Yufei found that this is the kind of hotel where you can see the sea outside as soon as you open the window, but relatively speaking, it must be more expensive to live here. However, Sun Kexin fell in love with this at a glance, and of course Li Yufei would not have any opinions. In Sun Kexin's words, that is, if there is an opinion, I will keep it.

An ordinary couple's set costs more than 700 a night. But fortunately, Li Yufei and they live on the first floor, and at night, they can completely open the floor-to-ceiling windows and go to the beach to play. It's very convenient. Seeing this, although Li Yufei didn't say anything, his heart was still very excited.

Today they were tired from running all day. First ran down from the mountains, then ran to gamble on stones, and then went to the countryside to eat seafood, and then took a yacht to the sea to watch dolphins, until it was dark and then came to Sanya. Even Sun Kexin's physique shouted tired.

No, as soon as they returned to the hotel, Sun Kexin didn't want to move, there was no way, Li Yufei had to ask the waiter to deliver the food to the customer, and then accompanied Sun Kexin to have a sumptuous dinner.

"Husband, have you dealt with all those stones today?" After eating, Sun Kexin finally had the strength to ask Li Yufei this question. In fact, she wanted to ask for a long time, but there were always outsiders on the side, so she didn't speak. Now it's just the two of them, and of course she's going to ask. As for whether Li Yufei told her or not, she didn't know.

"Why did you suddenly ask about this, don't worry, I'll find someone to cut them all. But it's a pity that only one of the four pieces has jadeite, but our luck is good, you see, this is what I asked them to cut out, glass imperial green, how about it, if it is sold, it is estimated that it will be worth tens of millions. Li Yufei took out a fist-sized jade that had been prepared a long time ago.

It was taken from one of their wool pieces. In the space, he is a god-like existence, and it is very easy to take out a jadeite. In order not to make Sun Kexin suspicious, he had already thought about what to do.

Li Yufei took out one of the pieces of wool, and now as soon as Sun Kexin asked, he pretended to take it out of the bag on the side, and sure enough, when Sun Kexin heard that only one of the four pieces came out, she was still very depressed, but when she saw the jade that Li Yufei took out that was a little bigger than her fist, she didn't think about anything at that time, and directly snatched the jade in Li Yufei's hand, and then held it and almost drooled.

Women are naturally fond of these things, and it can be said that there is no one from the age of three to eighty who does not like jewelry. Of course, Sun Kexin will not be an exception. A woman sees these things like your western dragon sees shiny things, and can't help but want to take them for herself.

At this time, Sun Kexin didn't think about anything else at all, she only had this jade in her eyes. Who made it so fascinating?

"Okay, don't look at it, give it to me first, this time our luck is not bad, we bought six pieces, three of them came out of jadeite, and the success rate reached half, not to mention that now with such a piece of jadeite, it can be said that it has risen sharply." (To be continued......)
