Yu Hua is the type of writer what I call historians. Like many of his generations, he went through cultural revolution (including living right across from where blood merchants did), open and reform policy, up till now the rapidly developing new China. He writes about what happened to him or what he saw happen to others, as simple as that.
His Chinese skills are mediocre, meaning I doubt he has the talent for the Chinese language.
His books are lacking in illuminating brainstorms.
What made him so popular among Chinese people? In my opinion, he writes about misery, Chinese people love to hear about other people's miseries to make themselves feel better, it is a placebo.
The novel To live is no better than a couple of Chinese TV series.
