Introduction to the official room: The official room displays the official sedans and ceremonial guards of academic and political affairs, including an official sedan that Li Hongzhang, an important military and political official of the late Qing Dynasty and the main advocate of the Westernization Movement, once sat in. Academic officials had to go to various places to select talents and hold academic examinations every three years, often with a grand display of ceremony, which shows the importance of the imperial examination system.
