King Qian Liu of wuyue lived in fourteen states. Before the Tang Dynasty, East Zhejiang and West Zhejiang were two independent regions. Zhedong Road is centered on Yuezhou (now Shaoxing); West Zhejiang Road takes Suzhou as the center. At that time, Hangzhou was only a third-class small country between the two big States, and it was often flooded by Qiantang River, with poor land and few people. Lin 'an is a small border county under this third-rate state. Only when Qian established Wu Yueguo, with Hangzhou as its capital, and the army building department in Lin 'an, which spanned eastern and western Zhejiang, governed Suzhou and Yuezhou, and then extended to Fuzhou and other 14 state armies, did the status of Hangzhou and Lin 'an suddenly rise.

In the Tang Dynasty, the county was changed to a state. From north to south, there were 13 states in Zhejiang at that time: Runzhou (now Zhenjiang), Changzhou, Suzhou, Huzhou, Hangzhou, Taizhou, Wenzhou, Quzhou, Yuezhou (now Shaoxing), Mingzhou (now Ningbo), Zhou Mu (now Jiande) and Shuozhou (later changed to Chuzhou, now Jiande).

At that time, Guan Xiu, a poet, dedicated a poem "Send money to your father" to Qian Liu, in which there was a famous sentence "Three thousand guests were drunk and fourteen States were frosted with swords". However, as mentioned above, there are only thirteen states in Zhejiang, and Runzhou and Changzhou are not under the rule of wuyue. Of course, Wu Yueguo still thinks that Runzhou is his own territory, because Qian Liu worked as a town navy in the Tang Dynasty, and the resident of the town navy was Runzhou.

However, in central wuyue, Zhejiang and Zhejiang really became "fourteen states", because Suzhou was divided again! In 940, wuyue established Xiuzhou in several counties in the east and south of Suzhou, and the state capital was located in Jiaxing County. After adding Xiuzhou, it became fourteen states, worthy of the name.

Although the fourteen states of Zhejiang and Zhejiang have all been realized, there are always two states ruled by others, which is really annoying after all. So Wu Yueguo has been spying on the changes in Nantang, a neighboring country. In 974, Song Jun attacked Nantang, and Wu Yuejun finally "recovered" Changzhou and Runzhou, and captured Nanjing with Song Jun the following year.

After Qian Hongchu's return to the Song Dynasty, China returned to the historical track of "great unification". In the Song Dynasty, everything remained the same except that the "Tao" in the Tang Dynasty was changed to "Tao". So two Zhejiang roads became two Zhejiang roads.

(Fourteen States) In Song Dynasty, Liang Zhedao governed two states and twelve states (Pingjiang Prefecture, Zhenjiang Prefecture, Hangzhou, Yuezhou, Huzhou, Yaozhou, Mingzhou, Changzhou, Wenzhou, Taizhou, Chuzhou, Hengzhou, Yanzhou and Xiuzhou), collectively referred to as fourteen states (see Geography of Song Dynasty).

Since Xiuzhou left Suzhou, most of the divisions between Zhejiang and Zhejiang have been fixed, especially the boundaries of southern state capitals have been stable for more than 900 years. But the name is still changing. For example, after the Fang La Uprising, Song Ting changed Zhou Mu to Yanzhou in order to "teach" the local "rabble". In the Southern Song Dynasty, Suzhou became Pingjiang Prefecture, Xiuzhou became Jiaxing Prefecture, Hangzhou became Lin 'an Prefecture, Yuezhou became Shaoxing Prefecture and Mingzhou became qingyuan prefecture.

A brief introduction of the background at that time, the above, I hope to help you.
