My system is not decent

The ancient ship No. [-] in the mouth of the Yangtze River "broke through the waves" before the end of [-].

Now this ancient ship named Changjiang Estuary No. [-] is placed on the century-old site of Dahai Shipyard.

An ancient ship museum will also be built on the site, that is to say, the No. [-] ancient ship at the mouth of the Yangtze River will "settle down" on the banks of the Huangpu River.

This is Chen Wenzhe's example. As long as he finds a nearby place and puts his sunken ship in place, it will definitely form a linkage effect with this ancient sunken ship No. [-] in the Yangtze Estuary.

After you have seen the No. [-] Changjiang Estuary in the Qing Dynasty, do you also want to see Chen Wenzhe's ancient shipwreck of the Song Dynasty?
Compared with this merchant ship from the Qing Dynasty, Chen Wenzhe's ancient ship is obviously more attractive.

Of course, the reason why the ancient sunken ship No. [-] in the mouth of the Yangtze River is famous must be because there are many treasures transported in it.

Looking back, Chen Wenzhe knew better what happened that year.

This is a somewhat controversial ancient shipwreck, that is, more than 150 years ago, this wooden ship full of valuables such as Jingzhen porcelain, purple sand ware, and hookah jars produced in Nanyue, suffered a shipwreck accident in the Yangtze River Basin.

Today, 150 years later, looking at the material on board, it will feel strange.

If it is an imported ship, what about the Jingzhen porcelain on it?

If it is an export ship, what about the hookah cans made in South Vietnam?

Except for Chen Wenzhe, no one else can verify the cause of the shipwreck.

It's a pity that Chen Wenzhe didn't need to check the historical pictures bit by bit, because it wasn't necessary, after all, it wasn't the sunken ship he salvaged.

Therefore, the experts who salvage the sunken ship can only rely on the ancient hull and mottled traces to uncover the story behind that journey.

The ancient ship No. 5.5 at the mouth of the Yangtze River is a wooden sailing ship, which was confirmed to be in the Tongzhi period of the Qing Dynasty. The hull was buried in the silt at a depth of 27 meters, and the horizontal tilt was about [-]° to the left.

Judging from what Chen Wenzhe observed, the type of ancient ship is suspected to be a flat-bottomed sand ship that was widely used for sea transportation in the Ming and Qing Dynasties.

Such a ship should not be able to carry out ocean voyages.

In the early salvage, a large number of Jingzhen porcelains were found on ancient ships.

If it was just Jingzhen porcelain, Chen Wenzhe really wouldn't care too much about it.

It's just that every shipwreck is a treasure house, and it will surprise people more or less.

No way, no matter what kind of merchant ship it is, why should it bring some good things?
In ancient times, or simply in the Qing Dynasty, the most famous export commodities in China were porcelain, tea and silk.

Therefore, as long as one's luck is not too bad, one can gain something when hunting for treasures on this ancient ship.

On the No. 60 shipwreck at the mouth of the Yangtze River, a [-]-centimeter-high blue and white porcelain was found.

Archeology and piracy are definitely not the same thing.

Chen Wenzhe can know from looking back that the sunken ship was discovered in [-] years, but it was salvaged in [-].

At that time, in order to further understand the nature and age of the Yangtze River Estuary No. 2016 ancient ship, starting from [-], the Dahai City Cultural Relics Bureau and other departments conducted underwater archaeological exploration and multidisciplinary research on the shipwreck site every year.

After more than six years of underwater archaeological investigation and exploration, the basic situation of the Yangtze River Estuary No. 6 ancient ship was initially ascertained.

...

According to the simulation animation, it was only determined whether the ancient ship No. [-] in the Yangtze River Estuary was a wooden sailing ship and what era it was.

Others include the water depth of the waters where the ship is buried, the depth of the hull buried, the surrounding environment and so on.

Finally, the exact data was obtained. The ancient ship was about 38.5 meters long and 7.8 meters wide. It has been proved that there were 31 cabins.

The structure of the upper part of the sunken ship, such as the sharp bow, the collar pile, the main mast, the starboard and starboard sides, and the upper deck, is complete.

The archaeologists selected four of the front and rear cabins and carried out a small-scale cleaning, and found that there were neatly stacked Jingzhen kiln porcelain and other exquisite cultural relics in the cabins.

In addition, purple clay vessels, hookah tanks produced in Nanyue, and remnants of wooden buckets were also unearthed in and around the hull.

In addition, there are some things on the ship, such as masts, large hardwood ship materials, iron anchors, brown cables, pulleys, metal drill bits, drill pipes, and a large number of cultural relics such as black minerals.

From July to September 2021, the Dahai City Cultural Relics Bureau once again organized a professional underwater archaeological organization to conduct an underwater survey of the No. 7 ancient ship in the Yangtze Estuary and its surroundings.

They cleared out the Yuan Dynasty porcelains that were not found in the previous investigations, and large porcelains such as the 60 cm high complete bean-green glazed blue-and-white vase.

In particular, the inscription "Tongzhi Nianzhi" on some of the out-of-water porcelain at the bottom of the ancient ship provides an important basis for the dating of the ancient ship.

The sunken ship of the Qing Dynasty contained foreign goods on it, so was it an imported ship or an exported ship?
The most important thing is that there are still some Yuan blue and white flowers on this ship, especially a large blue and white vase with a height of [-] centimeters, which is quite interesting.

In this way, it is quite normal for Chen Wenzhe to salvage shipwrecks of the Qing Dynasty and find porcelains from the Song and Yuan dynasties.

However, Chen Wenzhe was a little surprised when he inspected the salvage process of the sunken ship.

Because he found that salvaging sunken ships in the Yangtze River Estuary was not at all easier than salvaging sunken ships at sea.

Because the No. [-] ancient ship in the Yangtze River Estuary was severely scoured by the current, especially as the water potential and flow direction of the Yangtze River Estuary changed, the riverbed changed from silting to rapid downcutting, causing the ancient ship to emerge from the surface of the riverbed at an accelerated rate.

As a result, the hull faces serious security threats, which also brings great challenges to salvage.

At present, there are three main salvage methods for underwater shipwreck archeology around the world.

The first is to dismantle and salvage the sunken ship after extracting the cultural relics on board.

The second is to use cofferdams to pump water and salvage sunken ships after archaeological excavations.

The last one is to use a special caisson to salvage the sunken ship, cultural relics and the surrounding sea water and sediment according to their original state by hoisting, floating, and transporting them as a whole.

At that time, in order to prevent the ancient Yangtze River Estuary Ship No. [-] from being destroyed by nature and man-made, experts suggested that it should be salvaged as soon as possible and moved to a fixed place for archaeological excavation, cultural relic protection, research and display.

Due to the extremely high turbidity of the water body in the Yangtze River Estuary, the underwater visibility is almost zero, and the working time for leveling the tide is very short, so it is impossible to complete scientific underwater archaeological surveying, mapping and photographing operations.

At the same time, the time and cost required for underwater archaeology and the construction of cofferdams are huge, and the archeology behind the cofferdams will hinder the waterway for a long time.

Therefore, after listening to expert opinions, assessing the risks faced by the sunken ship, and comprehensively analyzing the three archaeological and protection methods, the Dahai City Cultural Relics Bureau decided to adopt an overall salvage method for the ancient ship No. [-] in the Yangtze River Estuary.

The overall salvage can relocate sunken ships with the shortest time, minimum cost, and maximum preservation of historical information.

The salvage method is determined, and the salvage method is also very important.

The staff at that time specially designed the salvage method in view of the high sediment content and fast water flow in the Yangtze River Estuary, as well as the particularity of the ancient ship and its surrounding environment.

The experts in charge of this ancient ship salvage mission decided to salvage this ancient shipwreck by adopting an innovative solution unprecedented in the world - arc-shaped beam non-contact overall migration of cultural relics.
