The Haishi officials said this: "In the eighth year of Jianchu, Zheng Hong was a Grand Secretary. He suffered from the contributions of the seven old Jiaozhi counties to transfer their fortunes. They all came from Dongye (Fuzhou), and went to the sea, and the storms were difficult and obsessed with each other. Hong reported to open Lingling and Guiyang Jiao Road (Shan Road). During the reign of Emperor Wu, General Fubo Road, Bode attacked Nanyue, left Guiyang, and went down to the old road of Huangshui, so Yitong was opened, and it has become a Chang Road until now."

After a brief pause, the Haishi official said: "After Fubo General Ma Yuan dredged the waterway in the south of Lingqu, went to Guishui (Beiliujiang), dug Guimen Pass, and then connected to Hepu River. In the ninth year of Emperor Heng's Yanxi, Zhou Jing of Xia Pi served as the prefect of Guiyang and dredged Lechanglong. At this point, water, land transportation, north and south, and the counties of the South China Sea began to reach the Shang Kingdom, with their clothes and rituals and music education."

"How is Zhou Fujun acting? Let's talk about the feelings before and after," Zhou Hui suddenly said.

"The commander should know that Guiyang connects to the South China Sea, the county boundary of the Qin River enters Shixing River, and reaches Quhong (Shaoguan) and connects to the South China Sea, and business travelers radiate and gather. However, from the water pavilion to Quhong, a water in the gorge is called Wuxi. It is also known as Longshui. Its water source comes from Guiyang Wangqin Mountain, passes through Linwu, enters Lechang, and combines the water into the water to form a turbulent stone. It has many stones in the water, and many boats hit and sink. Zhoufujun ordered people to penetrate the mountain diamonds, carve stones through the boats, row the rocks, throw them into the valley, shovel high and fill them down, carve straight curves, and open Jiulong Shiba Beach, so the stream water is straight, and the water path is straight. After the water was cleared, ship merchants from the South China Sea counties traveled and passed through Zhenyang to Quhongjin (Pingshi). Quhongjin became a place where merchants from north to south gathered. As a result, they flourished and rituals and music flourished. Later, there was Lingling Quhongchang District, where Zhou Fujun was built to commemorate the temple on the Tail, and the "Classic of the Merits of Zhou Fujun, the prefect of the God of Guiyang, the Shenhan Guiyang Prefect" was celebrating its merits. Guiyang, Nanhai and other places also built temples to commemorate it, calling it good governance. (Zhou Jing) and Wei Sa, Cichong, Luanba, and Xu Jing were also called the "Five Dukes" of Gui County. They were virtue and had long lived their famous lands."

Speaking of this, the Haishi officials couldn't help but feel fascinated.

"From the pre-Qin period to the Han dynasties, famous officials from all dynasties continued to penetrate Lingnan. They turned into barbarians, and made great achievements." Zhou Hui also felt the same way. He changed his tone: "Previously, when the Zhou Mansion was dredging Lechanglong, where were the former officials of the craftsmen now?"

"It has been twenty years since the ninth year of Yanxi..." Haishi Ling suddenly said: "The underside of the monument (back) of the meritorious officials are engraved with the names of meritorious officials who have been in charge of water. I will tell you just by asking."

"In this way, please send someone to do it quickly." Zhou Hui said.

"Here." Haishi Ling then went to pass on the order.

When the stern door is opened, a crane is hidden in the water. Go down the Li River, go to Guilin, and arrive at Panyu. Then go against Wuxi River (Beijiang), pass through Zhenyang, and run to Quhongjin. Looking for capable officials who have been scattered among the people for twenty years to govern the water.

Zhou Hui led his own fleet, went west to Yushui in Guangxin, Cangwu, and went to Hepu Port.

"The Duwei, the front is Fubojin." Shortly after entering the Guishui River, soldiers came to report. Later, the Guishui River was commonly known as Beiliu River, but it was named because its water flowed northward.

"Boat." Zhou Hui looked up the shore with a thousand-mile mirror.

"Yeah." The Youlin ship was big and deep, and could not approach the river bank. It anchored the river channel, flipped the wings, and bridged and docked with ships of all sizes in turn.

Here is a wild ferry. There are settlements on the shore, but there is no pavilion chief Li Kui. I heard that he was the commander of Shuiheng, and the tour came here. The people from Ye Du hurriedly lined up to greet him. The old man in front of the team said that he was a descendant of the Han army. He also told him: This place was originally an old county of Zhulu (Yulin) in the former Han Dynasty. In the 19th year of Jianwu in the Han Dynasty, General Fubo Ma Yuanping and the conquered Zhulu.

Zhou Hui asked again: "Where is the Hepu water?"

The old man also said, "I live here about twenty miles behind Guimen Pass."

Zhou Hui said suspiciously: "There are only more than twenty miles apart, so why not dig a canal and ship to travel?"

The old man said again: "The commander didn't know that the two waters were separated by Darong Mountain. This mountain was high in North Sakae and low in South Sakae. Therefore, the Gui River flowed north to the north and the Yushui River, while Hepu flowed south to the sea. If the canals were dug, the northern water flowed south, and the Gui River channel became congested and shallow, so it was impossible to sail. Hepu overflowed the river channel due to the large increase in water volume. Therefore, General Fubo abandoned the ship and landed on the shore and dug Guimen Pass to connect to Hepu."

Zhou Hui then realized: "It turns out that the terrain is unfavorable."

"That's true." The old man pointed to the mountain pass and said, "If you cross this pass, you can see the Fubo camp. The ditches next to the camp can connect to the Hepu water. It was built by General Fubo. There was a ferry under the city, which was very convenient to travel to Hepu."

Zhou Hui clasped his fists and thanked: "Thank you for your advice."

"I dare not." The old man retreated.

Zhou Hui looked around and said, "Is there any good solution?"

Then there was a boatman who came close to him and replied, "You can follow Lingqu and set up a 'Doumen'."

"What is the 'doumen'?" Zhou Hui asked happily.

"Doumen, also known as steep gate, has a Doumen built in the canal. Whenever the boat enters, it will be re-locked. The water accumulates and the boat gradually advances. Therefore, it can follow the cliff and walk down to connect the boats and oars from the north and south." The craftsman said this in a leisurely manner. The principle of Doumen is very similar to that of the locks in later generations.

"In this way, we should imitate the Ling Canal and set up a bucket door to connect the two waters." How can we bear to change the boat?

"What is this canal called?" asked the craftsman again.

"After passing through Rongshan, you will call 'Rongqu'." Zhou Hui's inspiration appeared.

"Here." The craftsman received the order.

The waterway was interrupted, and the Youlin was unable to go south. Zhou Hui was not anxious. He ordered the fleet to station on the spot. GF skilled craftsmen surveyed the terrain and chose the location to dig canals.

Another six hundred miles of letter to Ji State was sent to explain the details. King Ji then held a court meeting to discuss the matter of Tongqu.

In the eyes of King Ji, although Doumen is called clever, it is far less efficient than the ship locks in later generations.

"...............Around sixty miles, nine (dou) gates are placed. When the boat enters one bucket, it will be re-gate, and water accumulates and gradually advances. The floating boat crosses the ridge and passes through the upper and lower parts. Even a thousand hu boat can also travel. The water control is clever and there is no such thing as a spiritual canal." The Zuo Guo ordered Huang Chengyan to take the picture in his hand and tell the people in detail.

"The two waters are only more than twenty miles apart, and it is time-consuming to set up a wide bucket gate." Liu Bei said: "Can you only open the second channel to allow the ships to pass through without any obstacles?"

"Only two canals are opened..." The officials of the temple were about to be the temple, and they all thought hard.

Seeing that no one answered for a long time, Liu Bei then took the picture board and drew a sketch.

Although Zuo Guoling was in front of him, Su Bo subconsciously stepped forward and took it with both hands. He was used to it.

After careful consideration, Su Bo had already realized: "Wonderful!"

The sketch drawn by King Ji is imitating Qianjin Gate Gate. The two water gates in front and behind the channel are opposite to the north and south. There is a overturned truck next to it, which can draw water inside and outside. Wait for ships to enter in line, the rear gate falls, and the channel is cut off. If you go north, use overturned trucks to inject water. When the water surface rises, it is even with Guishui or even exceeds, then open the front gate and release it. Go downstream.

If you go south, open the north gate first, wait for the ship to enter the channel, then go to the north gate first, and then open the south gate. With the deep water accumulated in the channel, you can go down the flow.

"What is this canal called?" Su Bo asked hurriedly.

Liu Bei said, "It's called the 'ship lock', which is easy to understand."

"The lord is wise. We can't wait." The Zuo Guo Ling Huang Chengyan also figured out everything. He turned the complex into simplicity and called it awesome.

"We will determine the size and materials of the temple, and pass the module to the commander of Shuiheng, 600 miles." King Ji said.
