Introduction to the Revolution Hall: The picture shows the precious documents and items related to Zhang Taiyan displayed in the Revolution Hall. Hanging on the far left is the Han kimono worn by Mr. Zhang Taiyan when he fought against the Qing Dynasty in Japan. After the second failure of the Revolution of 1911, Zhang Taiyan angrily went north to argue with Yuan Shikai as a scholar. As a result, he was imprisoned for three years. In prison, Zhang Taiyan once wanted to commit suicide, so he sent the kimono he wore when he was in exile in Japan to his wife and left it behind. As a souvenir.
