After Mr. Kang, on behalf of the Cultural Relics Appraisal Committee, gave some condolences to the on-site treasure appraisal experts, a member of the treasure appraisal expert group presented this small porcelain of unknown origin to Mr. Kang for inspection.

After a short period of thought, he said with certainty: "Although I have not seen the real thing, this should be the water floating sinan recorded in the literature." ”

When I heard Mr. Kang say this, the spirits of the people and members of the expert group who came with Mr. Kang were also lifted. Everyone's eyes were all attracted by this small water floating sinan, and they all wanted to see what was recorded in the legendary Chinese dedication.

After some sighing, when he learned that Fang Yong was the treasure holder of "Shuifu Sinan", Mr. Kang looked at Fang Yong.

According to Mr. Kang, Shuifu Sinan is only seen in the literature, and has not been seen in kind, and there is no physical specimen even in the national museum, only reproduced according to the description of the literature in modern times, that is to say, Fang Yong's "Shuifu Sinan" is a rare treasure.

"I'll rub!" I've found a treasure again! Fang Yong screamed in his heart.

Mr. Ji Xianxing, a researcher at the History Museum who accompanied Mr. Kang and a member of the expert committee of the National Cultural Heritage Society, carefully and repeatedly identified the "Water Float South", and believed that this Water Float was burned during the Yongle period of the Ming Dynasty, which was the application object at that time, and it was the compass used in ancient navigation - porcelain Water Float South.

Kang Lao continued: "According to relevant records, the compass was invented very early, with a history of more than 2,000 years. Shen Kuo, a famous scientist in the Northern Song Dynasty, mentioned the use of the compass in "Mengxi Bi Tan", and he once did four kinds of experiments on the compass, including the water float method——— which put the compass in a bowl with water to make it float on the water surface and indicate the direction. Shen Kuo's record in "Mengxi Writings" can be said to be the earliest detailed discussion of the use of the compass in the world. In the "Derivation of Materia Medica" compiled by Kou Zongshuang in the late Northern Song Dynasty, it is said in more detail that if you wear a few lamp grass on the compass, you can float on the water. ”

In order to verify the practicability of Shuifusinan, experts such as Fang Yong and Kang Lao conducted field tests at the Treasure Appraisal Center. Let the staff find the materials for the test, according to the records in the literature, first fill it with water, and then take the lamp grass core, and put the commonly used sewing needle into the lamp grass core and put it into the water, the sewing needle relies on the buoyancy of the lamp grass core to float on the water surface, and soon it is still. After asking for directions, the pointer was pointing north and south, and the test was successful.

"Wow!" At this time, the expert group could no longer control their mood, and they all tilted their heads to witness the miracle mentioned in the history books. This makes everyone have to marvel at the wisdom of the ancient working people!

The scales on the edges of the porcelain are still puzzling. According to a member of the expert group, according to the literature, the edge of the Shuifu Sinan container should be the Bagua, the Heavenly Stem, the Earthly Branch and the Twenty-Eight Houses, and a total of 24 directions should be expressed, but there is no physical object to examine, and the scale on the periphery of the central circle of this small porcelain needs to be further studied.

Mr. Kang also said: "There are three elements in the appraisal of the value of cultural relics, one is historical value, the second is scientific value, and the third is artistic value. ”

"Young man, I haven't asked your name yet? Where do you work? Kang Lao said with a smile to Fang Yong.

"Elder Kang, my name is Fang Yong, and I'm still in high school?" Fang Yong said brightly.

"Fang Yong! Shall I discuss something with you? Kang Lao asked Fang Yong.

"Oh no, he won't be my baby! You won't let me pay it! Fang Yong thought with some concern.

Kang Lao looked at Fang Yong's somewhat frightened look, and said with a smile: "Don't worry, I don't want your Shui Fu Sinan." That's right, on behalf of the National Cultural Heritage Appraisal Committee and the National Collectors Association, I borrowed it from you, so that we can do some research. Because this water float was first published, there are many places that need to be studied, especially for the study of China's navigation industry in the Song and Ming dynasties. ”

"The water float method occupies an important position in the history of the development of compass in China. It can be seen from the ancient documents and underground unearthed cultural relics that the water float compass has been used in navigation since the Song Dynasty and the Ming Dynasty and the early Qing Dynasty in China. Some were also used in the middle and late Qing Dynasty. Shen Kuo discusses in the book, still used by modern compasses and geomagnetic surveyors, and on a global scale, the application of the compass in navigation guided the discovery of the American continent by Columbus and Magellan's circumnavigation around the world. This has greatly accelerated the process of world economic development and provided an indispensable prerequisite for the development of capitalism. At present, the compass used in aviation and navigation is mostly based on a water floating magnetic needle. Kang Lao continued.

At this time, a group of experts also looked at Fang Yong, with a look of expectation in their eyes.

When Kang Lao said this, Fang Yong was also embarrassed. They have all risen to the top of the national righteousness, how do you say I should answer?

Although this thing has been in his hands for less than half a day, he is still a little reluctant in his heart, but Fang Yong still said generously: "Kang Lao, in fact, you don't say that I also know that this piece of porcelain can only be regarded as a collection in my hands, if you can use it as a study, maybe it can also help to study some ancient history and technology of our country." ”

"Fang Yong, you are really noble! The state will not let you contribute in vain. When the time comes, we will issue you a certificate, which is jointly issued by the National Cultural Relics Appraisal Committee, the National Collectors Association, the Palace Museum, and the Organizing Committee of this art festival, which is very authoritative. And we will also sign a loan agreement for you, and in about a year's time, we will return it to you immediately after researching. Maybe you can still see your name in some literature! Kang Lao said with a satisfied smile.

"Fang Yong? What is your mobile phone number? We'll be in touch when the time comes. Kang Lao asked.

"I'm sorry, Mr. Kang, I haven't bought a mobile phone yet? Only the phone at home, it is 0***-@@@@@@@." Fang Yong said.

At this time, Kang Lao said to a middle-aged man behind him: "Xiao Zhang, didn't the organizing committee give away mobile phones to some special guests?" Give my part to Fang Yong! Convenient contact when the time comes! ”

"Teacher Kang, this is not good!" The middle-aged man surnamed Zhang said with some embarrassment.

And Fang Yong also said to Kang Lao that he didn't want to.

"What's bad? I will give it when I say it! Kang Lao said a little angrily, turned around and said to Fang Yong kindly, "Fang Yong, originally I did something wrong with this matter, it stands to reason that I shouldn't force you, that mobile phone can be regarded as an apology to you." ”

After a period of strict formalities, Fang Yong got the appraisal certificate and the borrowing agreement of "Shuifu Sinan".

After handing over the "Water Floating Sinan" to Mr. Kang, Mr. Kang said that he was going to write a research article on this little thing, and when the time came, he would give Fang Yong the credit for discovering Shui Fu Sinan, which made Fang Yong's vanity ready to move. The expert group also said that it was ready to contact some museums that developed the maritime industry in the Song and Ming dynasties to find more information and conduct further research on them.

Walking out of the exhibition hall, seeing that half of the face of the sunset had submerged into the horizon, and the dusk was drifting with a slight cold wind, playing with the mobile phone given by Kang Lao in his hand, Fang Yong couldn't help but sigh: "Today's harvest is really big!" ”
