During the Three Kingdoms, Wu was called Eastern Wu or Sun Wu?

During the Three Kingdoms period, because Sun Quan's power developed in the Jiangdong area, there was a saying of Eastern Wu at that time, note that "Wu" at this time generally refers to the general name of Huiji, Wu County, Moling and other regions. However, whether Cao Cao issued edicts, edicts, knighthoods, canonizations, conquests, and marriages to Sun Quan, they were all carried out in the name of Emperor Xian of the Han Dynasty, so the official position called Sun Quan all official positions granted by the Han family, such as: begging for generals, comprehending Ji Taishou, and making Chengzhi County perform clerical affairs.

For example, on the eve of the Battle of Chibi, when Cao Cao sent a letter of persuasion to Sun Quan, he still called him "general". In private, the Cao Wei regime called Sun Quan as: Jiangdong Huang Xu'er, Dongwu Huangkou Xiaoru, Jiangdong Sun Thief, etc.

A year after the Battle of Chibi, Liu Bei, in order to show favor to Sun Quan, presented Emperor Han Xian with Sun Quan as the general of the chariot and cavalry, and led Xuzhou Mu (the imperial court naturally will not agree, but it is a form of going through the scene, and Sun Quan will not appreciate it if he disagrees). Later, after Cao Pi usurped the Han Dynasty and became emperor, in order to stabilize the regime and appease Sun Quan, he crowned Sun Quan as the king of Wu. Therefore, there is the saying of Sun Wu (at this time, "Wu" no longer refers to the ancient name of the region, but is referred to as the name of the country).

Because it is the Three Kingdoms, later historians called Cao Wei, Sun Wu, and Shu Han, but these are all unofficial titles. After Sun Quan became the emperor and the founding name of the country was "Wu", the historians were all commensurate with the Wu State, and the history of the evolution of the title of the Sun family was probably like this, understand?

Eastern Wu, also known as Sun Wu because of the monarch's surname Sun.

There are also those called Sun Wu, compared to Cao Wei.

Three Kingdoms of Wu. It is now the south of the middle and lower reaches of the Yangtze River and South China. The state of Wu was one of the Three Kingdoms and was Sun Quan.

The regime established in southeastern China was called "Wu", known as Sun Wu in the historical circles, and ruled in the eastern part of the Three Kingdoms, so it was also called Eastern Wu.

The territory of Sun Wu Quansheng included most of Yangzhou and Jingzhou in the late Han Dynasty and the entire territory of Jiaozhou, and later divided the northeast of Jiaozhou into Guangzhou. Sun Wu vigorously developed the economy and made significant contributions to the development of the Jiangnan region. Sun Wu is the longest-standing state of the Three Kingdoms, with four emperors and a total of 52 years.

In the second year of Huanglong, Sun Quan sent Wei Wen and Zhuge to sail to Taiwan (then known as Yizhou) with the "Jiashi Wan" directly, which was the first time that China's political forces reached Taiwan. On May 1, the fourth year of Tianji (280), Sun Wu was destroyed by the Western Jin Dynasty, marking the complete end of the situation of secession since the end of the Han Dynasty and the Three Kingdoms in China.
