I had first read 'The paper menagerie' as a stand alone story and loved it, so bought Liu's full short story collection. As you can see from the individual ratings below, I also loved the rest of the stories. The only one to drop below 4/5 was 'All the flavours', mostly because I don't think the structure and length entirely paid off. Outstanding pieces include 'State change', Simulacrum', 'The paper menagerie', and 'The man who ended history: a documentary'. Although the collection averaged 4.5, I'm bumping it up to 4.75 because the work is greater than the sum of its parts. 
 
It's hard to describe Ken Liu's writing style and subject matter. It's an easy to read, sci-fi, magical realism, literary, historical fiction, kind of genre. There were several times I looked up specific events referenced and learnt about Chinese and pan-Asian history. I found this incredibly enjoyable, the way history and culture are presented is informative, but in an appeasing way because it's told almost like a fairy tale. I also greatly appeciated the author's notes at the end of the stories with historical features explaining the references and pointing to further reading. 

The stories cover difficult themes such as imperialism, industrialisation, migration and immigrant experience, ethical use/misuse and philosophical development of technology, revolution and nationalism, militarianism, philosophy of communication and memory, and censorship, all with respect to Chinese people.
