Scene Overview
The First Contact at Red Coast Base is the narrative origin of the entire Three-Body trilogy. This event took place in China during the 1960s and 1970s, against the bloody backdrop of the Cultural Revolution, at a top-secret military facility codenamed "Red Coast" hidden deep in the Greater Khingan Mountains of northeastern China. It was here that astrophysicist Ye Wenjie performed the most consequential act in human history — sending a signal into the cosmos, receiving a reply from an alien civilization, and then, fully aware of the consequences, choosing to invite that civilization to Earth.
Detailed Description
The Trauma of the Cultural Revolution
Ye Wenjie's story begins in the brutal years of China's Cultural Revolution. Her father, Ye Zhetai — a physics professor at Tsinghua University — was beaten to death by Red Guards during a public denunciation session, and among the perpetrators were his own students. Ye Wenjie witnessed her father's death with her own eyes, and this scene became the deepest trauma of her life. Her mother publicly disavowed her father to protect herself, and her younger sister Ye Wenxue became a fanatical Red Guard. Through this catastrophe, Ye Wenjie lost her most fundamental faith in human nature.
Afterward, Ye Wenjie was sent to a production corps in Inner Mongolia. There, a book — Rachel Carson's Silent Spring — entangled her in a political trap. Journalist Bai Mulin used her to draft a letter about environmental destruction, then shifted all blame onto her when political winds changed. Betrayed once again, Ye Wenjie was charged with counter-revolutionary crimes.
Red Coast Base
In a twist of fate, Ye Wenjie was transferred to Red Coast Base — a top-secret military installation atop Radar Peak in the Greater Khingan Mountains. The facility's ostensible mission was to monitor signals from outer space, though it also carried out high-power signal transmission toward the cosmos using the sun. The base was overseen by Political Commissar Lei Zhicheng and Engineer Yang Weining.
During her work at Red Coast Base, Ye Wenjie discovered a critical physical phenomenon: the sun could serve as a signal amplifier. When electromagnetic waves of specific frequencies were directed at the sun, its energy layers could amplify the signal by hundreds of millions of times before radiating it into space. This discovery meant that humanity possessed the ability to send powerful signals into the depths of the cosmos without constructing impractically enormous antennas.
Ye Wenjie reported this finding to base leadership, but political considerations initially kept it shelved. Eventually, Red Coast Base used the solar amplification effect to send humanity's first interstellar signal into the universe.
The Reply from the Trisolaran World
One day, eight years later, Red Coast Base's receiving system captured a signal from the depths of space. After Ye Wenjie deciphered it, the message's content was staggering:
"Do not answer! Do not answer! Do not answer!"
This warning came from an individual in the Trisolaran star system — a "pacifist" of the Trisolaran world. This pacifist had risked execution by secretly using communication equipment to send this warning toward the signal's source. The message was clear: the Trisolaran civilization had received Earth's signal and had determined Earth's general direction. If Earth replied again, the Trisolaran civilization would precisely pinpoint Earth's location, and a Trisolaran fleet would be dispatched.
This was the first message humanity had ever received from an alien civilization. By any rational logic, this warning should have filled its recipient with terror and compelled silence.
Ye Wenjie's Choice
Yet Ye Wenjie made the opposite choice.
On that fateful night, Ye Wenjie was alone in Red Coast Base's transmission control room. Before her was the transmit button; behind her was half a lifetime of trauma. The atrocities of the Cultural Revolution, her father's murder, her mother's betrayal, her sister's fanaticism, the collective silence of intellectuals, the ubiquitous malice of human nature — all of it crystallized in her mind into a cold conclusion: human civilization could no longer correct its own errors through its own efforts. Humanity needed intervention from an outside force.
Ye Wenjie pressed the transmit button and sent her reply to the Trisolaran civilization:
"Come here. I will help you conquer this world. My civilization is no longer capable of solving its own problems. It needs your force to intervene."
This message was amplified through the sun and transmitted toward the Trisolaran star system. The signal crossed four light-years and reached the Trisolaran world. The fate of humanity was forever altered in that instant.
Guarding the Secret
After sending the reply, Ye Wenjie faced the risk of exposure. Political Commissar Lei Zhicheng and Engineer Yang Weining (who was also Ye Wenjie's husband) successively discovered her secret. Ye Wenjie was forced to take extreme measures — using the cover of an accident, she killed both men, ensuring the secret would not be revealed. This act marked Ye Wenjie's complete transformation from victim to cold-blooded operative — for the sake of what she believed was "saving the Earth," she was willing to pay any price.
Analysis
The First Contact at Red Coast Base is one of the most psychologically profound scenes in the entire Three-Body series.
The Logic of Trauma and Despair: Ye Wenjie's choice was not an impulse but the inevitable result of accumulated trauma. Liu Cixin devoted extensive chapters to establishing the Cultural Revolution's psychological devastation of Ye Wenjie. She had lost her most basic faith in human civilization — not disappointment in a particular person or system, but despair toward the entire human species. In such despair, the arrival of an alien civilization was not a threat but a hope — even if that hope might mean the destruction of human civilization.
The Irony of "Do Not Answer": The Trisolaran pacifist's warning "Do not answer!" constitutes a profound irony. The warning itself proved that the Trisolaran world was not monolithic — goodwill and conscience existed there too. But the person who received this warning was precisely someone who had completely lost faith in human goodwill. A benevolent individual of an alien civilization tried to save humanity, while a human individual chose to betray her own civilization. This cross-civilizational twist of fate is profoundly ironic.
The Individual and Civilization: Ye Wenjie's act raises a fundamental philosophical question: does one person have the right to make decisions on behalf of an entire civilization? Based on her personal judgment — that human civilization was beyond redemption — Ye Wenjie decided to invite an alien invasion. This decision would affect the fate of billions, none of whom had any knowledge of it. This asymmetry between individual action and civilizational consequence is one of the deepest themes of the Three-Body series.
Contingency and Inevitability in History: If Ye Wenjie had not experienced the Cultural Revolution, if her father had not been killed, if she had not been assigned to Red Coast Base, if someone else had been on duty the night the Trisolaran signal arrived — humanity's fate would have been entirely different. But Liu Cixin suggests that within this contingency lies a certain inevitability: the dark side of human civilization would sooner or later find an outlet, and the cruel laws of the cosmos would sooner or later come for humanity.
Impact and Significance
The Beginning of the Three-Body Crisis: Ye Wenjie's reply directly led to the Trisolaran civilization's decision to dispatch a fleet to Earth. Four hundred and fifty years later, the Trisolaran fleet would reach Earth — this timeline forms the fundamental framework for all subsequent stories in the Three-Body series.
The Creation of the ETO: Ye Wenjie later established the Earth-Trisolaris Organization on Earth, recruiting disillusioned elites who had lost faith in human civilization, preparing for the Trisolarans' arrival. The ETO's activities became the primary conflict thread of the first novel.
The Cause of the Sophon Blockade: After confirming Earth's existence, the Trisolaran civilization sent "Sophons" — intelligent entities created by unfolding higher-dimensional protons — to monitor Earth and lock down humanity's fundamental scientific research. The Sophons' existence profoundly influenced humanity's strategic choices throughout the Three-Body Crisis.
The Original Sin: Ye Wenjie's act became the "original sin" of the Three-Body series — every subsequent disaster, war, sacrifice, and destruction can be traced back to that solitary night at Red Coast Base. This imbues the entire story with a sense of Greek tragedy — everything began with one person's choice, and that choice was itself the result of countless historical forces converging.
