During the Six Dynasties period, wars and chaos were frequent, and the smoke was connected to the smoke, and the withering was connected to the withering. However, because Ezhou Xiakou (present-day Wuhan) is located at the confluence of the Yangtze River and the Han River, it belongs to the transportation and military towns, Wuchang (present-day Ezhou) is also on the shore of the Yangtze River, once served as the capital of Eastern Wu, so the rise of ports and shipping in the two places, directly serving the transportation of soldiers and grain, shipbuilding industry also flourished, so that commerce in the fluctuations of the tortuous development, along with the gradual southward shift of China's economic center of gravity, especially Ezhou Xiakou, Hanyang after the Sui annihilation of Chen unified the country, Ezhou Xiakou, Wuchang regional economic pace in the history of Wuhan urban development history of the "twin cities" side by side.

From the end of the Eastern Han Dynasty to the Three Kingdoms period, a series of harbors mainly for military purposes appeared on the surface of the Yangtze River and nearby tributaries in Xiakou and its vicinity, and by the Southern Dynasty, it had developed into a large port.
Shaxiantun (present-day Jinkou Town, Jiangxia District) in Ezhou was a large military port of considerable size during the Three Kingdoms period at the end of the Han Dynasty. Liu Biaobu held Huang Zu here, and in the fourth year of Jian'an (199), Sun Ce broke Huang Zu here and captured 6,000 warships, whether this number is exaggerated or not is unknown, but it is enough to explain the size of the Ezhou Shaxian Military Port in that year. After the Battle of Shaxian in Ezhou, Huang Zu defeated lushan (present-day Guishan) and retreated to The Moon City, where Liu Biao appointed Huang Zu to open a large water division base for Jiang Xia tai punctuality in the first year of Jian'an.
Sun Quan continued to "attack Huang Zu in the west and break his boat army" in the eighth year (203), 12 years (207), and thirteen years (208) of Jian'an, and Huang Zu also "sent boat troops to resist the army", but Yuecheng was eventually attacked by Sun Quan. The so-called "boat army" and "boat soldiers" are water troops, so it can be seen that there should also be some military ports around Haoyue City.
The scale of the ancient city port of Xiakou in Sun Wu'ezhou was unmatched by Ezhou Shaxiantun and Yueyue City. On the eve of the Battle of Chibi, Liu Bei burned Xinye, was defeated by Cao's army at Dangyang, and fled to Xiakou, Ezhou, at which time Liu Qi also collected the remnants of his father Liu Biao and came to Xiakou, Ezhou. According to Zhuge Liang, Liu Bei's military strength still had "10,000 elite soldiers of Guan Yu's water army, and no less than 10,000 soldiers of Liu Qi's Hejiang Xia"; Guan Yu and Liu Qi were all water troops, with a total of more than 20,000 people, from zhuge liang's lobbying of Sun Quan, in order to impress Sun Quan and strengthen his belief in resisting Cao, Liu Bei's water army of more than 20,000 people was stationed in Xiakou, Ezhou.
And Sun Quan himself will also be a water army Tunzha Ezhou Xiakou, according to the "Romance of the Three Kingdoms. According to the biography of Zhou Yu, Zhou Yu, who was the former governor of the capital, had "invited 30,000 elite soldiers to enter xiakou in Ezhou", and the elite soldiers zhou Yu asked Sun Quan to get were naturally mostly water troops, and what they wanted to fight was also a water battle. Speaking of which, before the Battle of Chibi, the combined forces of Shu and Wu had more than 50,000 troops stationed in Xiakou, Ezhou. So many sailors tunza Ezhou Xiakou, enough to imagine the size of the ancient city port of Ezhou Xiakou during the Three Kingdoms period. In the last year of the Southern Dynasty, before Shen Youzhi's rebellion, Xiao Qing, the son of Xiao Daocheng, who ruled Xiao Daocheng, later Emperor Wu of Qi, once said to Liu Shilong, the defender of Yingcheng: "Once you change, burn the Xiakou boat ships in Ezhou and go east along the stream, then sit in the empty city and cannot be created", indicating that Ezhou Xiakou is the largest ship port in the upper reaches of the Yangtze River.
Ezhou Parrot Island, Nanpu, Huangjunpu, etc. are important military ports in Xiakou, Ezhou, in addition, the Book of Southern Qi. Zhang Chong's biography contains "Ezhou Xiakoupu", a simultaneous biography and the Book of Liang. In the Book of Emperor Wu, there is "Shiqiaopu", and "Pu" is a port, indicating that there are many large ports in Xiakou. Of course, under the objective reality of dynastic change and war, the purpose of these ports is mainly to serve military purposes.
During the Southern and Northern Dynasties of the Wei and Jin Dynasties, the river surface in the southwest and northeast regions of Ezhou Xiakou was much wider than it is today. Not only that, at that time, there were also many Jiangxinzhou in the river, and Ezhou Parrot Island was one of them. Regarding the location of Ezhou Parrot Island, the Ezhou Jiangxia County Article of the Yuanhe County Atlas records that "Ezhou Parrot Island is in the southwest of the county for two miles".
Another "Record of the Decline of the Taiping Dynasty": "Ezhou Parrot Island is two miles southwest of Xia County in the east of the great river, passing through this continent in the west, seven steps from the north, flowing in the middle of the great river, and dividing itself with Hanyang County." Its head rests on the mouth of the catfish, and its tail is connected to the yellow pigeon rock, which lies across the center of the river about two miles from the bank of the Wuchang River, and its orientation is roughly close to the dive island at the end of the current Wuchang Baishazhou. Some commentators have also pointed out that "Ezhou Parrot Island should be between the present-day Wuchang Catfish Mouth on the right bank of the Yangtze River and the Yuanjia River", and said that "by the Ming Dynasty, Ezhou Parrot Island was not found in historical records, which is likely to be the reason why the Bund of Jiangwan south of Snake Mountain has been connected with Ezhou Parrot Island to become the Bund", "Ming Dynasty Ezhou Parrot Island is no longer JiangxinZhou".
The largest area was once 2 million square meters of Ezhou Parrot Island, the end of the Han Dynasty began to become a tourist attraction, Huang Zu's son Huang She once held a grand banquet on the continent, the Eastern Han Dynasty celebrity You Heng also wrote the famous "Cockroach Endowment" impromptu, after You Heng was killed by Huang Zu and buried on the continent, hence the name. Because it is surrounded by water on all sides, the sandwich area between it and the banks of the Xiakou River in Ezhou is especially convenient for boats and boats to travel, and it has become an important place for military ships at the end of the Eastern Han Dynasty. In the first year of Liang Dabao (550), Xiao Lun, the king of Shaoling, came to Yingzhou to seek the scenery and built weapons in Yingzhou. Xiao Xuan, who was then the King of Xiangdong, feared that Xiao Lun's growing power would be unfavorable to him, so he sent Wang Sheng to lead 10,000 sailors to garrison Ezhou Parrot Island, and Xiao Lun fled to Wuchang (present-day Ezhou). In April of the following year, when Hou Jing sent Song Zixian to attack Shi Xiaofangzhu in Yingzhou, he also ambushed a large number of water troops in the area of Ezhou Parrot Island. Due to the success of this sneak attack, "Jing Chengsheng went west, 200,000 people, united flags for thousands of miles, and since Jiangzuo, the prosperity of the water army has not been achieved." Thereafter, in the ensuing battle of Wang Shengxue over The State of Zhizhou, according to the Book of Liang. Wang Borrowed a Biography: "The lord of the water army, Song Yu, led the building ships, and the dark river was clouded on all sides", and the grandeur of the warships could almost cover the clouds and cover the sun.
In the unification war of the Sui Dynasty and the destruction of Chen, Yang Juntuo, the king of Qin, led more than 100,000 troops out of Xiangyang and into Tunhankou, which was the upper class. Chen commanded Zhou Luo and Xun Fashang to command tens of thousands of troops in Tun'e Prefecture and block Yang Jun. These historical facts show that at that time, the port of Ezhou Parrot Island and even the entire Port of Xiakou in Ezhou had a considerable scale.
