What historical events happened in 208 AD?

At the end of the Eastern Han Dynasty, in the 13th year of Jian 'an (A.D. 208), the allied forces of Sun Quan and Liu Bei defeated Cao Cao's army in Chibi (now northwest of chibi city, Hubei Province) near the Yangtze River, which laid a famous battle of the three countries' separation and defeating the strong with the weak. This is one of the most famous wars in the history of China, and it is also the most famous one among the "three major battles" in the Three Kingdoms period. It is also the first large-scale battle in the Yangtze River basin in China history, which indicates that China's military and political center is no longer limited to the Yellow River basin.
