On this day, 59 years ago, on August 18, 1966 (July 3, 1966 in the lunar calendar), Chairman Mao Zedong received the Red Guards for the first time. On August 18, 1966, Mao Zedong wore the armband of Red Guards and inspected the Red Guards for the first time at the Beijing Tower. From then on, the Red Guards organization became popular across the country. On August 18, 1966, a "Mass Conference to Celebrate the Proletarian Cultural Revolution" was held in Tiananmen Square in the capital. Mao Zedong and others met with people and Red Guards from all over the country for the first time in Tiananmen Square. On this day, Mao Zedong, wearing a military uniform, met with people and Red Guards from all over the country in Tiananmen Square. He accepted and wore armbands presented by the Red Guards. After that, Mao Zedong interviewed the Red Guards many times on August 31, September 15, October 1, 18, November 3, 10, 11, November 25 and 26 respectively. By late November, he had interviewed Red Guards and school teachers and students eight times, reaching more than 11 million people. This shows that Mao Zedong actively supported the Red Guards 'rebellion movement and regarded the Red Guards and young students as a surprise force to launch the "Cultural Revolution" in an all-round way. Encouraged and supported by Mao Zedong's eight interviews with the Red Guards, scattered and sporadic rebel movements in various places quickly unified into the Red Guards, a popular organizational form across the country, and developed into a craze that swept across tens of millions of young people. At the same time, the Red Guards began a nationwide chain. On September 5, the Central Committee of the Communist Party of China and the State Council issued a notice stipulating that teachers and students coming to Beijing "all travel by train for free" and that "living subsidies and transportation expenses shall be borne by the state budget." Teachers and students from other universities and middle schools rushed to Beijing, while students from Beijing rushed to other places. In this way, a nationwide series began. Mao Zedong met with Red Guards and school teachers and students across the country eight times in three months, fueling this trend. Hundreds of millions of people are connected across the country, resulting in school suspension and production suspension across the country, railway congestion, traffic congestion, and social disorder. On March 19, 1967, the central government issued a notice on stopping the nationwide large-scale chain connection and decided to cancel the original plan to hold a large-scale chain connection after the warm spring. However, some people still contacted and connected outside until August, when the connected activities basically ended. The Red Guards kept shouting "Long live Chairman Mao! Long live! Thousands of years!" Mao Zedong reviewed the Red Guards 'motorcade and marched on Chang' an Street. Mao Zedong, Lin Biao and the Red Guards were together. Mao Zedong came to the middle of the Red Guards. The Red Guards walked in Beijing from the remote areas of Heilongjiang Province to the provincial capital of Harbin. The Red Guards bought the Selected Works of Mao Zedong at Xinhua Bookstore overnight
