More specifically, I did a little search and gave you the answer.

Wuhan is the capital of Hubei Province, a famous historical and cultural city in China, and the economic, cultural and information center in Central China and the middle reaches of the Yangtze River. It is known as the "thoroughfare of nine provinces".

Wuhan has a long history. As far back as the mid-Shang Dynasty more than 3,000 years ago, an ancient city was built on the north bank of Fuhe River, only 30 miles away from Hankou, and the site was excavated beside Panlong Lake. It can be seen that Wuhan has been an important ancient town since Shang and Zhou Dynasties.

Wuhan is the collective name of Wuchang, Hanyang and Hankou, namely "Three Towns of Wuhan". Wuhan has gone through a long historical process to become a big city.

The historical sequence of the three towns in Wuhan is that Jiangbei (Hanyang) precedes Jiangnan (Wuchang), while Hankou was only a barren land adjacent to Hanyang before the Ming Dynasty. So before the Ming Dynasty, the so-called "Wuhan" was the general name of Wuchang and Hanyang. In Yuan Dynasty, Wuchang and Hanyang belonged to Huguang province, and Hubei (Wuchang) and Han (Hanyang) were also called twin cities. Yu Que, a poet in Yuan Dynasty, put Wuchang in his poems. Hanyang is called "Twin Cities", which shows the trend of Wuchang and Hanyang from single name to combined name.

At the beginning of Chenghua in Ming Xianzong (146- 1487), Hanshui River was diverted into Minhe River, and Hankou was the city. But every summer when the water level rises and the river overflows, people still can't live in peace. 1635 (eight years of investigation by Ming Chong), it was decided that Yuan advocated building a long dike (starting from the bridge mouth and ending at the dike mouth) for flood control. This dike is called "Yuan Gong Dike", which is today's Long Dike Street. Since then, the number of residents has been increasing. During the Jiaqing period of Renzong in Qing Dynasty, the number of residents in Hankou had reached 36,929, which were 129 and 183 respectively. However, Hankou has been in Hanyang County for a long time, so the early concept of "Wuhan" was a general term for Wuchang and Hanyang. For example, in 1822 (the second year of Qing Daoguang), Fan Kai wrote the sentence "I fell into counties such as Wuhan" in Hankou Talk, referring to counties such as Wuchang and Hanyang, but Hankou was not a county (state). During the Xianfeng period, Hu Linyi, the governor of Hubei Province, often used the word "Wuhan" in his plays and letters, such as "Wuhan is the throat of Jingxiang", "If Wuhan is restored" and "Wuhan confronts the two cities". Obviously, it also refers to Wuchang and Hanyang (including Hankou of course), and "Wuhan" should actually be pronounced as "Wu and Han".

Hankou's independent status was established in 1899 (the 25th year of Guangxu), when Zhang Zhidong, the governor of Huguang, called for the sharing of Yang and Xia, changed Hankou into a common knowledge for the comfort of the people, and divided the northern part of Hanshui River in Hanyang into North Shekou and West Jiaokou, which were placed under the jurisdiction of common knowledge and named "Xiakoutang". In the early years of the Republic of China, Tongzhi was changed to the governor, and the government was changed to the county, so Xiakou County came into being. At that time, Wuchang (Jiangxia), Hanyang and Hankou (Xiakou) were still dominated by their respective names and belonged to each other. For example, Jiangxia belonged to Wuchang House in the late Qing Dynasty, Hanyang and Xiakou belonged to Hanyang House, and Xiakou belonged to Jianghan Road in the early Republic of China, so there was no unified administrative system. Historically, Hanyang and Hankou were also called "Yang Xia", and Wuchang and Hanyang were called "Wuyang".

/kloc-in the autumn of 0/926, the National Revolutionary Army conquered Wuhan. At the beginning of the following year, the National Government merged Hankou City (under Hanyang County) with Wuchang, included Jingzhao District as the capital, and established a unified Wuhan Municipal Government. At this time, Wuhan realized the title of administrative region and urban area. Since then, Wuchang, Hanyang and Hankou have been split in two. Until the eve of liberation of 1949, Hankou was a municipality directly under the central government, Wuchang was a provincial city and Hanyang was a county.

After liberation, the State Council merged Hankou, Wuchang and Hanyang (the seat of the county government and its adjacent areas) into Wuhan (the former Hanyang county moved to Caidian, retaining the county organizational system), and the Wuhan Municipal People's Government was located in Hankou. At this point, the three towns in Wuhan have truly merged into one.

Wuchang: During the Three Kingdoms period, Sun Quan established his capital in present-day Hubei, named Wuchang, and soon built a city in present-day Sheshan, named Xiakou; In 280 AD, the Jin Dynasty changed Jiangxia County to Wuchang County, which is the beginning of the name of wuchang city today, and later changed its name to Jiangxia until the late Qing Dynasty. Wuchang House was founded in Kangxi. After the Revolution of 1911, Jiangxia County was changed to Wuchang County, and Wuchang became the official name. ?

Hankou: During the Southern and Northern Dynasties, Hankou appeared as a place name in historical records. Today's Hankou actually has only a history of more than 500 years, which began with the diversion of Hanshui River during Chenghua period of Ming Dynasty. The Hanshui River was originally injected into the Yangtze River from the south of Guishan, and its mainstream was injected into the Yangtze River from Jijiazui in the north of Guishan during Chenghua years. After the diversion of the Hanshui River, the low-lying wasteland developed into Hankou, which is also known as the four famous towns with Zhu Xian in Henan, Jingdezhen in Jiangxi and Foshan in Guangdong. After the Opium War, Hankou opened a port for trade and developed more rapidly. ?

Hanyang: In 606 AD, in the second year of Sui Daye, Hanjin County was changed to Hanyang County, and the name of Hanyang began. After the county government moved to Hanyang City in the Tang Dynasty, it developed rapidly. At the beginning of 1927, Wuhan National Government merged Wuchang and Hankou (under Hanyang County) into the capital and named it Wuhan. Today, Wuchang, Hankou and Hanyang make up the "Wu Hancheng" with a history of only 74 years.
