From Strange Rebels: 1979 and the Birth of the 21st Century, by Christian Caryl (Basic Books, 2014), Kindle Loc. 2721-2761:
Most of these malcontents were incapable of articulating their demands. But someone was prepared to do it for them. In September 1978, the editors of a magazine called China Youth, which had been prohibited from publishing during the Cultural Revolution, decided to relaunch it. They decided to mark its return in style by publishing some poems commemorating the Tiananmen Incident of 1976. Party censors intervened and thwarted the editors from going ahead with their plans. The frustrated literati refused to give up, so they resorted to a time-honored technique of Chinese mass communication: the dazibao, or “big-character poster.” They decided to print the poems in poster form and paste them up in a public place. They needed a venue where a big audience was ensured, so they opted for a spot that other unrecognized writers had been using for a few months. This was a long stretch of brick wall under a row of leafless sycamore trees next to a bus depot in Xidan, a spot in downtown Beijing, just a few blocks from the Jingxi Hotel, that tens of thousands of commuters passed through every day.
China Youth’s decision to use the site dramatically boosted its notoriety. Crowds of readers quickly formed. To everyone’s surprise, the authorities declined to interfere. Posters proliferated. Soon people were coming from all over China to take a look. Crowds gathered, eager to experience the heady atmosphere of a place where a myriad of views competed for attention.
This was Xidan Democracy Wall. Young Chinese described it as their version of Speaker’s Corner in London’s Hyde Park. For a few weeks in the winter of 1978–1979, it would become a key strategic asset in the battle for China’s soul.
At some point in late November, a poster appeared on the wall criticizing Mao by name. No one could recall such a thing ever happening before. The author of the poster, who called himself Work Permit Number 0538 (and gave the address of the motor repair shop where he worked), wrote: “In 1976 after the Tiananmen Incident, the Gang of Four made use of the prestige and power of Chairman Mao’s mistaken judgment on class struggle and launched an all-out attack on the cause of revolution in China.” During the Cultural Revolution, one man had been sentenced to fifteen years in a labor camp for absentmindedly scratching his back with a copy of the Little Red Book during a mass meeting. Now everyone waited to see what would happen to the author of this shocking text. Would he be shot? Surely, at least, the poster itself would be torn down. But two days later it was still there.
The posters that followed pushed the boundaries even further. One wondered how the all-knowing Mao had failed to notice that his own wife, Jiang Qing, was actually a “traitor.” Another called on the party leadership to observe the rule of law. Another demanded the rehabilitation of party leaders who had been purged by Mao in the early 1960s. Not all of the provocations were political. “Why can’t the national economy catch up with the one in Taiwan?” one poster asked. “How can the United States, a capitalist country only 200 years old, be the most developed in the world?”
By now the wall was besieged by visitors, day and night. People read, expostulated, and listened “with an openness unprecedented in the history of the People’s Republic.” Some visitors spoke their messages through bullhorns. The foreign correspondents and diplomats who came to see what was going on found themselves besieged by curious locals. During the years of the Cultural Revolution, ordinary Chinese had done whatever they could to avoid even the most cursory contact with citizens of other countries. Now, liberated by the air of candor around the wall, they peppered the foreigners with questions. Roger Garside, a Chinese-speaking British diplomat who wrote one of the most vivid accounts of the early reform period in China, recalled the scene:
They bombarded me with questions on democracy and human rights: “Can you really criticize your Prime Minister? Who owns the newspapers in Britain? How do they decide their editorial policy? How is the BBC controlled? How are elections organized?”
Some were by no means ignorant but wanted to check out the information they had acquired one way or another; others were simply thirsty for knowledge.
In Garside’s description, Democracy Wall functioned like a sort of proto-Internet: posters with derivative content were quickly papered over, while those that had something new or powerful to say were left uncovered. Readers wrote comments on some of the posters with ballpoint pens; when a popular one was torn by accident, visitors quickly glued it back together. Some of the texts were written on scraps of paper torn from notebooks, while others were composed on sheets of paper three feet high with brush and ink. Some authors used paper in pink or green to attract attention.
