The bus written on the bus means: the Han Dynasty was responsible for receiving letters from subjects and official signatures for enlistment, and later it also meant that Juren took the exam in Beijing. Originally refers to petitioning or writing in Beijing, but also refers to people who try to write in Beijing.

The bus petition in history refers to that in the 21st year of Guangxu in Qing Dynasty (1895), Kang Youwei led thousands of juren, including Liang Qichao, to jointly write a letter to Emperor Guangxu in Qing Dynasty, opposing the Qing government defeated by Japan in the Sino-Japanese War to sign the treaty of shimonoseki, which humiliated the country. This is regarded as a sign that the reformists stepped onto the historical stage, and it is also the beginning of China's popular political movement.

The background of Letter on the Bus is the Sino-Japanese War of 1894-1895, when China was defeated by the Japanese. 1in the spring of 895, the B-class scholar finished his exam in Beijing and waited for the list to be released. The sudden news that treaty of shimonoseki ceded Taiwan Province Province and Liaodong and compensated 22,000 yuan reached Beijing, and the people who took the exam were furious. Taiwan Province juren is crying.

Historical influence

Although the bus petition and the Reform Movement of 1898 failed successively, the reform thought awakened and inspired more and more China people to save the country, which played an important role in the modern history of China and opened the prelude to the reform movement.

"The letter on the bus indicates that the trend of bourgeois reform and political reform, which has been brewing for many years, has developed into a political activity of patriotism and saving the country, which has had a huge impact and shock on society. Since then, Kang Youwei has achieved a leading position in the Reform Movement.
