For readers with limited science and history knowledge to handle the Chinese author's Three Body Problem, this collection of short stories (The Wandering Earth ) is the perfect book to get familiar with Liu's work. I read the Chinese version but will also seek out the English translation. As someone who learned my scientific vocabulary in American high school and university, Chinese science terms are really not my strong suit. Liu's science fictions are often described as "hard science fictions." He is extremely knowledgeable with real science, yet creative enough to use these information in his stories. Amazing.
