Classic story "Patriotism and Prosperity"

Zhuge Liang in the Three Kingdoms period helped Liu Bei seize the land in West Shu, captured Meng Huo seven times, formed an alliance with the local people, consolidated the southwest border defense, and made the southwest truly become the rear area of China's dynasties, making great contributions to safeguarding national unity. The Erhai Lake in Dali still has a memorial site for his training. On the contrary, at the same time, Cao Cao invaded Xianbei people in order to expand his territory, which led to the destruction of gold in the Northern Wei Dynasty. So later, both novels and operas praised Zhuge Liang to the sky and slandered Cao Cao as a traitor.
