I am not Song Qinzong

Among them, the straight roads formed in the Qin Dynasty and the Grand Canal formed in the Sui Dynasty formed the basis of land and water transportation in China.

Water transportation is the first choice for people to travel because of its large cargo capacity and low loss.

After looking at it for a while, Zhao Huan sighed: "Although Kaifeng is big, it is still a prison. How can I feel happy when I come out."

"The yamen is in the midst of blessings and doesn't know the blessings. Look at the coolies who row boats. I'm afraid they want the blessings in their dreams." Liu Ziyi said bluntly.

"Haha~" Zhao Huan laughed and said, "Do you have any articles for this situation?"

"Who dares to write in the yamen?" Chen Chaolao said with a smile.

It has been two days since they came out, and Zhao Huan's freshness is still not over, and he still keeps sighing.

Liu Ziyi understood that it was not easy for the prince, and always accompanied him to talk casually. Anyway, the journey was long, and he was idle when he was idle.

"Huh? Why did the boat stop?" Feeling that the boat was slowing down, Zhao Huan asked in surprise.

"Ya Nei." Li Cheng turned a small boat over and said, "The front is the water city, and we need to line up to get in and out. Do you want to flag and pass quickly?"

In order to avoid delays in visiting the government along the way and ushering in the delivery, Zhao Huan directly hired a private boat to conceal his identity.

Of course, the banner token is always with you, and you can use it at any time if you need it.

Just like the current situation, if you are in a hurry, you can fly the flag of the Eastern Palace. If you see the official and civilian ships along the way, of course you must take the initiative to give up the channel.

After checking the identity at the checkpoint ahead, they must be released immediately.

"How long will it take to pass in line?" Zhao Huan asked.

At this time, the water surface of the canal remained motionless, and the boats stopped completely.

It's just that the anchor has not dropped, so it is convenient to continue sailing at any time.

"There are more than a hundred boats gathered ahead, and it will take about half an hour to wait." Li Cheng replied.

Zhao Huan pondered for a moment, and said: "It's not long, let's go through the line."

It's worth waiting half an hour, and it's not worth exposing your identity for this.

"Here." Li Cheng went to the front and informed the ships.

There are ten ships in total, with the prince in the middle, fifty personal guards distributed on the ship and the two ships in front and behind, and five hundred forbidden troops distributed on each ship.

Because Li Cheng is proficient in water, he led a hundred soldiers in the front as a vanguard.

However, the boats on the river can't keep a distance.

The boat stopped for half an hour, and the water surface of the canal suddenly flowed forward at a very high speed. The oarsmen took advantage of the situation to row the oars and controlled the boat to move forward.

It was just deliberately suppressing the speed so as not to slow down enough to crash into the ship ahead.

After walking for a while, the current stopped and the boat stopped.

Looking forward, a city wall traverses both sides of the canal, which is quite majestic.

It can be seen that the soldiers above are holding knives, guns, bows and arrows, looking forward and backward.

"This is Water City?" Zhao Huan asked.

"What the yamen said is true." Zhang Bofen replied, "This city was built because of the sluices, and the river guards all made their living from it."

Zhao Huan said: "Let's talk about it in detail."

"Because going south, there is a section of the drop that is quite high, and it was impossible to sail.

In order to facilitate the passage of ships, two sluices were built at the drop. The front sluice is opened, and the water channel in the sluice is filled with water, so that the ships ahead can enter smoothly.

When the ship arrives in front of the rear gate, close the front gate and open the rear gate, the water will flow out from the rear and the water surface will be even and unimpeded naturally.

As for the river guard soldiers, they are specially responsible for repairing the embankment of the canal, dredging the river, and maintaining order on the water surface.

Its command post is near the sluice. Over time, the natural population has gathered to form a market town.

Because the salaries of the Xiang soldiers were too low to support their families, these people set up checkpoints in front of the sluice to collect the gate fee.

Later, various tax supervisors also came here to inspect tax deeds and crack down on private businessmen, so the scale expanded day by day, from the gate to the city. "Zhang Bofen explained.

"So it is!" Zhao Huan said clearly.

This water city has changed from the original passage to a toll station.

So, the toll booths of the expressways in later generations are also the wisdom of the past?

While talking and laughing, the boat arrived in front of the water city.

This section of the canal uses the Bianshui channel, and the water surface is 140 steps ([-] meters) wide. The city wall spans both banks and extends a lot to the bank.

About three feet high, there is a tower in the middle, and on both sides are "Huainan East Road Transshipment Department", "Household Tax Supervision Department", "Fengyang Town Inspection Department", "Zhibianshui Fingyang Town Command and Envoy Department" and so on. brand.

Huainan East Road Transshipment Department was established here, which shows the geographical advantages of the place.

Looking down, there are three water gates on each side of the city tower. The large, medium and small three can supply large and small ships to pass at the same time.

The water gate in the middle of the river is five feet wide and two feet high, three feet wide on the side, and one foot wide on the outside, all of which are arched.

The cast iron water gate fell into the water, which not only blocked the boat, but also made it difficult for the water to move.

Probably the ships inside were empty, and when the flag bearer waved the flag, there was only a creaking sound, and the gate slowly rose.

It can be seen that the undercurrent on the water surface is surging, bringing out whirlpools.

After a while, the gate opened.

The boats lined up in a row and entered the water gate one by one. Next to it, there were boats slowly sailing out.

Orderly, no chaos.

The canal has been used for many years. Not only the government has experience in governance, but the people also know how to operate it.

When the ship was laying from bow to stern, there was only a plop, and the gate fell.

The ships stopped.

This speed is much faster than the half an hour Li Cheng said.

"How can you know how to operate the canal after reading thousands of books and traveling thousands of miles without leaving Tokyo?" Zhao Huan sighed.

"Yeah, you can only know the greatness of manpower when you see it with your own eyes!" Liu Ziyi also sighed.
