At the end of the Eastern Han Dynasty, why did Lu Su choose to build Yuejun Tower in Dongting Lake?

As early as the end of the Eastern Han Dynasty, Yueyang was named Baqiu. Located in Shan Zhinan, the shogunate of Tian Yue, the north of Dongting Lake was renamed Yueyang. There are endless fields and plenty of fish. At the intersection of rivers and lakes, it is the gateway of Jingxiang.

In the Chibi War, Cao Jun advanced and retreated through Baqiu. After the war, Baqiu was the meeting place of two military groups, Sun and Liu.

In 2 15, Lu Su replaced Zhou Yu and was stationed in Baqiu. He believes that "Baqiu is just the intersection of rivers and lakes, extending in all directions, and it has been the land of land and water wars since ancient times, and the water war in Yuli should become an important naval stronghold."

After Liu Bei borrowed Jingzhou, Guan Yu was stationed to confront Lu Su. During Lu Su's stay in Baqiu, in order to prevent Guan Yu and Cao Jun from going south again, he stepped up the training of naval forces in Dongting Lake, which has a vast surface.

He chose Dongting Lake and the throat of the Yangtze River, which was later Yueyang Tower, built a dangerous and solid Baqiu City, and built a reading building for the training and review of the water army at the high place near the lake in the west of the city.

The reading army building stands on the shore. Boarding the military tower, you can see the Dongting, every sail and wave in the lake. The momentum is extraordinary. This military reading building is the predecessor of Yueyang Tower on Dongting Lake in Yueyang, Hunan. According to Baling County Records, Yueyang Tower "originated from Han and Jin Dynasties", or "Lusu Yuejun Tower".
