Three body

Three body by Liu Cixin tells an epic of human's Odyssey to the universe, spanning 20000 Earth years. It's a great science fiction in many ways,  full of dazzling imaginations and thrilling plots. It integrates the traditional Sci-fi, Chinese Wuxia, game theory, fairy tales, moral dilemma, history, and humanistic concern.

Scientifically, he invents the concepts like universe sociology, universal axioms, dark forest, interstellar deterrence, photon attack, dimension attack, light-speed spaceship, wall-face plan, and staging plan. It presents a grand picture of the human future with significant progress in science, yet still a dust in the universe. it describes the endless cycling of war and peace, as well as human ambition and desperation. He cleverly avoids the detail images of three-body,  leaving a "white" for the readers to fill. 

Philosophically, he projects the conflicts of human ideas to the aliens, and creates a dread scene of natural selection.  In the last-day war, we can see the familiar ethical dilemma of killing for survival in the lifeboat case of 1884. Interestingly, we can see the book is affected by Philip Dick from the plots in "The shadow of the man in the high castle" (the invasion of three-body) and "Mr. Spaceship" (sending brain to the space). However with all the dreadful fates, he leaves us the hope of better survival with exploration and love.

I don't like the first book of the trilogy because of its superficial dialogues and plain characters, but I do like the second the third book of the trilogy with much better plots, thoughts, and structure.
