Cai Que put his forehead on his face.

"Mr. Cai, but there is one place to be investigated."

"where?"

"Xiuzhou Qinglong Town."

Cai Que laughed: "Qinglong Town will say later, Duan Tianshui, what do you think Cheng Fang?"

These two people were deliberately found out by the subordinates of Cai Que's clan.

The court asked Cheng Fang to be the river management envoy and presided over Hebei water conservancy. Duan Tianshui was once Cheng Fang's most important disciple and made great contributions. Later, under the attack of Wen Yanbo and Han Qi, Wang Anshi did not shelter him. Cheng Fang died of depression and Duan Tianshui was so scared that he went home.

Therefore, Wang Anshi does not know how to use people. The reason why the reform has some highlights is nothing more than Wang Shao's military affairs, Xue Xiang's financial management, and Cheng Fang's water conservancy. However, none of these three people ended up well and did not get Wang Anshi's real value!

Duan Tianshui said carefully: "Although the envoy Chenghe was eager to achieve success, the people thought they had made every mistake in the court."

He looked at Cai Que's face and added: "But Cao people think that in a thousand years, future generations will give Cheng He a higher evaluation."

Although Wang Ju "rehad" Cheng Fang, because Cheng Fang was eventually a eunuch, he dealt with this rehabilitation in all aspects, and the impact was limited. At most, he gave him some official positions and gave his relatives some rewards. Therefore, it seems that the court did not do enough. However, the status of eunuchs in the Song Dynasty was very low, just like the eunuch Li Xian, but in fact he was just like that in politics.

And thousands of years later, how many people know about Cheng Fang?

Cai Que also disagreed with it, thinking that Wang Zian had asked Cheng Fang for justice, what else would he think of a eunuch?

But he was quite satisfied with Duan Tianshui's words, turned his head and looked at Zhang Jian and said, "Okay, let's talk about Qinglong Town first."

He rolled up the map above, and there was still a map below, a map of Huating County.

Huating County was later Shanghai, but there are many differences from Shanghai later. First, there is a part of Jinshan in the southeast corner moving with the rising and collapsed northwards of Qiantang River. Later, it disappeared under the sea, but the area was not too large. It was from the line between Chuansha and Nanhui in the east, and under the sea. There is also Hengsha Island, Changxing Island did not surface, and Chongming Island is now just a few small islands.

However, Huating County does not cover the entire Shanghai. From north of Wusong River, Jiading and Baoshan belong to Kunshan County, Suzhou. However, Huating County does not include the later Shanghai city, Qingpu, Songjiang, Chuansha, Nanhui, Fengxian, Jinshan, and some of the Jiashan and Pinghu areas in Zhejiang. In terms of area, it is the number one county in the southeast.

There is no Huangpu River now, so there is no distinction between Pudong and Puxi.

Finally, there is Dianshan Lake. There is no Dianshan Lake now, but it is composed of several lakes. The largest lake was named Guhu since the Qin Dynasty. It was not until the Southern Song Dynasty that Mateng Lake, Guhu and other lakes were connected together to form Dianshan Lake. However, in the Southern Song Dynasty, it was not called Dianshan Lake, but Xuedian Lake. But it does not mean that the area of ​​Dianshan Lake is now, just one Guhu Lake is larger than the later Dianshan Lake. Although several lakes gradually connected after decades, due to artificial surroundings of the lake, sea tides flow back, waterlogging, and silt, the silt at the bottom of the lake is constantly eroded by wind and waves, and the area of ​​the lake becomes smaller and smaller.

However, only Wang Ju understands these four changes a little.

Cai Que looked at the confused eyes of the two and gave a simple explanation.

China developed the southeastern region earlier, and Wu and Yue fought for hegemony, that is, during the Spring and Autumn Period, the civilization in this area was no longer behind the Central Plains civilization. However, the development of the Xiuzhou area, especially the Shanghai area, was relatively late. Although Huating County was less harmful to the Qiantang River tide, the river tide was very large at this time, with two tides hitting the sea tides, and the sea tides were pouring back from time to time. Although the rivers were densely populated in the northeast, there was only one main road of the Wusong River in the northeast. Therefore, when the typhoon came or when the autumn broke out, the flood water in the upper reaches rolled in, but it could not be discharged in time, so the flood water was severe.

However, when the Five Barbarians invaded China, a large number of people in the Central Plains fled south, and many people came to this area and defected to local Lu families and other wealthy families, becoming their tenants and tribes. The population gradually became dense and began their first development.

Then in the Tang Dynasty, more areas rushed out of the sea. However, due to the uneven heights and soft land in these areas, they often triggered sea rushes. Therefore, the Tang Dynasty government started from Haiyan in the west and went east to the south bank of Wusong River, building a long sea embankment of more than 100 miles, and at the same time a county was established. This was the first time that Shanghai was officially established in the county.

This was the second development. Since the population became more dense, some ships went up the Wusong River and traded in Qinglong Town. At this time, agriculture in Shanghai began to become more developed, so Qinglong Town became a commercial center.

But the real development was from Wu and Yue to the Song Dynasty, which was the third major development. During the Wu and Yue period, the Dushui Camp and the Leqian Army were specially built, dredged the Wusong River and managed the Dianshan Lake, and established many steep gates, embankments and irrigation ditches. On this basis, the Song Dynasty further developed and created many fields, cabinet fields, vegetation fields and trench fields. The fields and vegetation fields refer to the planting of crops and trench crops on the water surface. The fields and trench fields are planted on floating wooden rafts. In addition, smear fields and sand fields appeared. In addition, the government intends to introduce wheat in the north and Chameng rice in the south. At this time, the agriculture in Shanghai gradually became the same as the fishery. The population also grew from 10,000 households in the early Song Dynasty to 10,000 households.

For a county, there are already many 100,000 households, but it cannot be said that it is extremely densely populated. After all, it is too large in area. Because it accumulates fertile fields, the yield per mu is five or six stones, so the people it can accommodate is far from reaching its limit.

However, even if it has not changed, it continues to develop. Not only is it a fishing and rice town, but there are many salt farms in the southeast. Because the people are rich and the commerce is developed, the wine industry has flourished. Therefore, the Song Dynasty established a wine business on a tributary of the Wusong River, called Shanghai business.

By the end of the Northern Song Dynasty, the Song Dynasty established the civil service and the Southern Song Dynasty further developed. Therefore, the Maritime Service was directly established in Qinglong Town, and the Shanghai Affairs Office was changed to Shanghai Town. Shanghai Town was later Shanghai City. At the end of the Southern Song Dynasty, the population expanded to nearly 200,000 households, called Little Hangzhou.

Cai Que didn't know what the Southern Song Dynasty looked like, and he continued: "Although Huating is good, it is still only on both sides of the Wusong River."

"Mr. Cai means that there is no main river in the southeast to discharge floods?" Duan Tianshui asked.

Cai Que nodded. Because there was no main river in the southeast to discharge floods, even though the Song Dynasty developed on a large scale, the southeast was still mostly lake terrain, with only fisheries and salt industries, and rarely agriculture.

At the same time, the river tide is large, and there is only one main river channel with high tide and low tide. The tide is very fast, and the ship is unsafe to drive, especially the bulky large sea boats are not easy to drive. Even small ships can only drive into Qinglong Town and park in Qinglong Town is located in Qingpu, far from the estuary, and slightly affected by the tide.

Therefore, although the Southern Song Dynasty established the Maritime Warehouse Department in Qinglong Town, it never reached the height of other Maritime Warehouse Departments. With the accumulation of Wusong River, many ships were transferred to Shanghai Town to moor, and Shanghai Town gradually replaced the status of Qinglong Town, and then the sea ban came.

Cai Que said this and drew a line on the map with his pen. Duan Tianshui and Zhang Jian looked at the line and said repeatedly: "My, wonderful."

"I'm going to Huating County, are you willing?"

Cai Que's words made the two of them change their faces to be continued.
