We discover that it's the future: China has constructed a huge mirror in space called the China Sun, and is using it to engineer the climate. Ah Quan gets a job cleaning the reflective surface of the China Sun. It turns out that Stephen Hawking is living in orbit, where the low gravity has helped to prolong his life; Hawking and Ah Quan become friends and go on space walks together. The physicist teaches the worker about the laws of physics and about the vastness of the universe, and Ah Quan’s mind begins to dwell on the question of humanity’s fate: Will we explore the stars, or live and die on Earth? Soon afterward, he is saying goodbye to his parents and setting out on a one-way mission to explore interstellar space. By the end of the story, Ah Quan’s progress is representative of humanity’s. He has traversed an enormous social and material distance, but it pales in comparison to the journey ahead.
我們發現書中描述的是未來的世界：中國在太空建造了一面巨大的鏡子，它被稱為“中國太陽”，用于調節氣候。阿全的工作是清潔“中國太陽”反光表面。原來斯蒂芬·霍金（Stephen Hawking）生活在軌道上，因為那里的重力小，他的生命得以延長；后來霍金和阿全成為了朋友，一起去太空漫步。這位物理學家向這個工人講授了物理學定律和宇宙的浩瀚，阿全的內心開始思考人類命運：我們要去探索其他星球嗎？還是就在地球上度過一生？不久，他就向父母告別，踏上了探索星際的單程之旅。故事結尾，阿全取得的進步代表著全人類的進步，盡管他跨越了巨大的社會和物質距離，但與未知的旅程相比，這顯得微不足道。

Liu’s stories aren't always so tender; in imagining the human future, his romantic sweetness is balanced with harsh objectivity. In "The Wandering Earth," scientists discover that the sun is about to swell into a red giant. In response, they build enormous engines capable of pushing the entire planet toward another star—an "exodus" that will last a hundred generations, during which everything on the surface will be destroyed. Watching the deadly sun recede and transform into a star like any other, the protagonist cries out, "Earth, oh my wandering Earth!" And yet the story suggests that this is just the sort of outrageous project we'll need in order to insure humanity's long-term survival.
劉慈欣的故事不完全是這么溫和的；在想象人類的未來時，他筆下的浪漫甜蜜與殘酷現實是相輔相成的。在《流浪地球》（The Wandering Earth）中，科學家們發現太陽將要膨脹為巨大的紅色星體。因此，他們建造了巨大的引擎，這些引擎能夠將整個地球推向另一顆恒星——一場持續上百代的“大遷移”就此展開。在此期間，地球表面的一切都將被摧毀。看著致命的太陽漸漸遠去，變得模糊，最后變得與其他星體無異，主人公哭喊著“地球，我流浪的地球啊！”然而，這個故事向我們暗示了，我們需要種種匪夷所思的解決方案來保證人類的長存。

"In the distant future, if human civilization survives and spreads through the cosmos, humanity must create technological marvels at ultra-grand scales," Liu wrote to me.
劉慈欣在郵件中寫道：“在遙遠的未來，如果人類文明在宇宙間生存繁衍的話，人類必需創造超乎尋常的科技奇跡。”

I believe science and technology can bring us a bright future, but the journey to achieve it will be filled with difficulties and exact a price from us. Some of these obstacles and costs will be quite terrible, but in the end we will land on the sunlit further shore. Let me quote the Chinese poet Xu Zhimo from the beginning of the last century, who, after a trip to the Soviet Union, said, "Over there, they believe in the existence of Heaven, but there is a sea of blood that lies between Heaven and Hell, and they’ve decided to cross the sea."
我深信，科學技術能夠給我們帶來光明美好的未來，但是實現的過程會充滿艱難險阻，我們要為此付出代價。其中有些阻礙非常艱難，有些代價非常高昂，但是我們終將抵達陽光明媚的彼岸。請允許我援引上世紀初中國詩人徐志摩在游歷前蘇聯（Soviet Union）之后寫下的詩句：“他們相信天堂是有的，可以實現的，但在現實世界與那天堂的中間隔著一座海，一座血污海，人類泅得過這血海，才能登彼岸，他們決定先實現那血海。”

But to what end? Humanity can't survive everything; the last volume of the "Three-Body" trilogy is set, in part, during the heat-death of the universe. Liu’s stories see life from two angles, as both a titanic struggle for survival and as a circumscribed exercise in finitude. In my favorite of his stories, "The Mountain"—it's available in English in a short-fiction collection called "The Wandering Earth"—mountain climbing is proposed as a metaphor for this contradiction. "It is the nature of intelligent life to climb mountains," inter-dimensional alien explorers explain. But the universe is so unknowable that "we are all always at the foot," and will never reach the peak. In another story, "The Devourer," a character asks, "What is civilization? Civilization is devouring, ceaselessly eating, endlessly expanding." But you can't expand forever; perhaps it would be better, another character suggests, to establish a “self-sufficient, introspective civilization." At the core of Liu's sensibility, in short, is a philosophical interest in the problem of limits. How should we react to the inherent limitations of life? Should we push against them or acquiesce?
但是，終點在哪里呢？人類無法保存一切；《三體》三部曲的最后一部中，部分情節設定在宇宙熱死亡期間。劉慈欣的故事從兩個不同角度來審視生命：一個是為生存而頑強斗爭，一個是在界限內受限制的行為。在他所有作品中，我最喜歡的是《山》（The Mountain）——在短篇小說集《流浪地球》中有它的英文譯本——此文以登山作為這個矛盾的隱喻。跨緯度的外星探索者解釋“登山是智慧生命的本質”。但是宇宙神秘而不可知，以至于“我們總是在山腳下，”且永遠也到不了頂峰。在另一個故事《吞食者》中，書中人物問“什么是文明？文明就是吞食，不停地吃啊吃，不停地擴張和膨脹。”但是你不可能永遠在擴張，另一個人物建議道，也許建立一個“自給自足的、內省的文明”會更好，另一個人物這樣建議。簡而言之，一言以蔽之，劉慈欣的理性內核是對極限問題的哲學思考。我們應該如何應對生命固有的局限性？我們應該反抗，還是認命？

"Everything ends," Liu said, in his e-mail, "and describing what is inevitable should not be viewed as a form of pessimism. Take the example of a romantic tale: 'The lovers lived happily ever after' would clearly be viewed as an optimistic story. But if you add a coda—'A hundred years later, they were both dead'—does that turn the story pessimistic? Only science fiction can go as far as 'a hundred years later' at the scale of the universe."
劉慈欣在郵件中提到：“沒什么是永恒的，描述必然性不應當被視為一種悲觀主義。就拿愛情故事來說，‘戀人從此幸福快樂地生活在一起’我們當然認為這是一個樂觀的故事。但如果你在結尾再加一句——‘百年過后，他們兩個都去世了’——難道就變成了一個悲觀的故事了嗎？只有科幻小說可以描寫‘百年之后’的浩瀚宇宙。”
