But by the morning of June 3, troops were trying to enter the square, and students and residents tried to block them from doing so. Pressed up against each other, they could only use songs to win the battle. As the soldiers withdrew to the Great Hall of the People, they won applause and praise from the students, and sang “Long Live the People's Liberation Army” as they marched away.

No one would have thought the order to “clear the square” would be given that evening.

Fourteen army and airforce groups, nineteen support groups, and a combined total of over 200,000 troops were mobilized from the Beijing and Tianjin Garrison Commands. Their orders were to enter Tiananmen Square from all sides, and were given permission to open fire on civilians — they were not to hesitate at any cost.

Gunshots rang out in the vicinity of Tiananmen Square; residents were gunned down from Muxidi and Xidan in the west, the Qianmen neighbourhood in the south, and Nanchizi Street in the east.

In an era without digital communication, the students in Tiananmen Square were largely unaware of what was happening around them. Fang Zheng and other students were still there at 10pm, and received word that the PLA would soon be upon them. Some had taken bloody clothes to the square and showed them to everyone. The atmosphere suddenly became tense.

At 11pm, a solitary armoured vehicle burst into the square. Students pelted it with molotov cocktails, leading it to drive erratically, colliding with everything.

Writer and Nobel peace prize laureate Liu Xiaobo (劉曉波) was an eyewitness to the events that night. In the documentary film “The Gate of Heavenly Peace” he said this about the scene:

All of a sudden, the loud speakers in Tiananmen Square started to broadcast an urgent notice to the martial law forces. It said the state had made its decision to suppress the counter-revolutionary forces, and they were not to hesitate at any cost. In just half an hour, more than a hundred thousand people had evacuated the square. The only people left were those standing beside the Monument to the People’s Heroes. We were absolutely terrified.

By 2:30 in the morning, the PLA had surrounded the students in the centre of the square. Fang Zheng was one of them. He remembers that there were still three to four thousand students left. Some were from Beijing universities, others were students from outside the capital region. Fang was joined by 20 of his classmates from the Beijing Institute of Physical Education. Some of them sat by the Monument to the People's Heroes, while others sat around the Goddess of Democracy — a statue built by student protesters.

Liu Xiaobo, as well as Taiwanese singer and activist Hou Dejian (侯德健), tried to persuade the students to retreat at 3:30am. Hou got in a car and went looking for an officer in charge of the martial law forces, and asked him to negotiate with the students. A political commissar reported the situation to his superiors, and asked Hou to convince the students to leave the square.

In the end, students voted to leave, with one picking up a microphone to announce an immediate evacuation of the square. As they left, they sang “The Internationale” with tears welling up in their eyes.

The students fled in all directions. Fang Zheng was not a protest leader, and followed everyone else out of the square. A younger classmate of his was also at the scene, and he asked her to follow him.

They left Tiananmen Square from the south, then were forced to walk north. By 6am, they were only one kilometre away from the square, and just outside the gates of Zhongnanhai — the seat of political power in China.

As Fang Zheng walked on the roadway, he heard an explosion and smelled smoke behind him. Some people said troops were firing tear gas, but Fang has always thought it was some sort of poison gas shells. A shell went off beside him, releasing a yellow and green smoke. He couldn’t see anything within a two to three metre radius, and felt dizzy and suffocated.

Fang tried to get himself and his classmate to a safe position on the sidewalk, and tried to push her over the one-metre railing separating the road from the pedestrian walkway. But just as he was doing so, a tank appeared through the smoke. Fang turned his head, but still couldn’t see the tank in full view, just that it was in front of him.

As he pushed his classmate onto the walkway, Fang fell on the road, with his upper body still up against the railing. The tank crushed his legs, and rolled him up in the process. His entire body was jolted by the tank’s caterpillar treads, and then dropped with a thud at the back of the vehicle.

“The entire thing happened in less than 15 seconds, from the poison gas shells hitting the ground, to me losing consciousness from the pain of being run over by a tank,” said Fang.

Ten years later, someone showed Fang a photo taken on June 4, 1989. In the photo, the protagonist is leaning against an iron railing, with his trousers torn, and his legs bloody and broken. Bystanders blocked his face, but Fang could tell by the clothing that he was the person in the photo.

THE SOLDIER FACES THE PEOPLE, THE STUDENT FACES THE POLICE

Some people at the scene jotted down the number of the tank that crushed Fang Zheng's legs -- "106". Scholar Wu Renhua (吳仁華) says the unit in question was from the Tianjin Garrison, and under the command of one Luo Gang (羅剛). His unit was responsible for 11 accounted deaths and many more serious injuries. Luo’s unit is suspected of a number of unaccounted deaths as well.

Meanwhile, Li Xiaoming's unit was driving in circles on the outskirts of the city for the entire day. When they stopped in the evening beside a rice paddy, no one was in the mood to talk and barely anyone slept. But on June the 5th, at 6am, an operations director from the 38th Army rolled up to their position in an armoured vehicle, and escorted the 116th Division to Tiananmen Square.

After troops opened fire, there was almost no one on the streets of Beijing, and there were no road obstacles moving forward. But as they crossed an overpass, they heard screams of "fascists" and "butchers" and felt a rain of bricks from the surrounding buildings. A soldier in his unit named Li Wei (李偉) shot off a few rounds, pelting Li Xiaoming with the falling shells. Li Xiaoming yelled at him to stop, and Li Wei didn't shoot again that day.

Around 9am, the 116th Division arrived at the already devastated Tiananmen Square. Tank tracks scarred the marble steps leading to the Monument of the People's Heroes, and the square was littered with clothes and tents left by students. Li Xiaoming rummaged through the rubble and found a pair of bleck leggings and coat littered with bullet holes and blood. He didn't find a body, but a fellow soldier told him they found "a whole pile of bloody clothes" during the clean up.

In one traumatic incident near the square, Li says a company commander named Yu Xuejun (于學軍) ordered soldiers to disperse a crowd of stragglers near the Xinhua News Agency building. Yu ordered soldiers to shoot in the air to scare off the crowd, but Li later one soldier brag that he "offloaded an entire clip into the crowd." With one AK-47 clip carrying 36 bullets, “he would be responsible for more than a dozen casualties,” said Li.

Eight kilometres away, Fang Zheng was waking up at Jishuitan Hospital. The pain was severe; his right leg was amputated to the upper thigh and his left leg was amputated to the knee. He heard from the medical staff, that he was first sent to Erlong Road Hospital, closer to the scene of the incident. But because of the severity of his injury, he couldn't be treated at Erlong.

He told medical staff he was a student at the Beijing Institute of Physical Education, leading the hospital to contact his school, who in turn contacted his family. Fang's family immediately made for Beijing from Hefei, the capital of rural Anhui Province.

By then, the situation was stable in Tiananmen Square. Li's unit was stationed in the area for two days, and was then ordered to enforce martial law in other parts of the city.

The 116th Division headed east towards the Beijing International Hotel near Fuxingmen Overpass. Out of nowhere, they heard gunshots from the top of the hotel, and the entire division got out of their vehicles. They knelt on the ground and fired at the building, sending shattered window glass to the ground. Li says the shards fell like glistening snowflakes. Bullets had even hit apartment building reserved for the foreign diplomatic core behind the hotel. The following day, many foreign embassy officials left Beijing for good.

On June 8th or 9th, anxious nurses told Fang Zheng that troops were about to take over the hospital, and arrest "counter-revolutionaries" who took part in the protests. Fang was still in poor health, and any movement would make his condition worse. So medical staff wheeled his bed into a power supply room, and locked the door.

After a while, nurses came back for Fang and told him it was a false alarm. It wasn’t soldiers at all, but police from the public security bureau looking to question patients and staff. From that day on, Fang Zheng began a 30 year personal journey recounting his experience on June 4th, 1989.

LEAVING THE TOTALITARIAN STATE BEHIND

Fang Zheng left China more than 10 years ago, and Li Xiaoming has lived in Australia for nearly 20 years.
