I think this kind of comparison is unfair. When Mo Yan and Yu Hua were growing up, creative writing didn’t exist as an academic major at all, and higher education was far less widely available. Many writers of their generation never received a college education, but that was more like an exception produced by their time.
In today’s Chinese literary world, it is still very hard to get published without connections. And we can see how many bad writers, like Jiao Dian, manage to enter a strong creative writing program, become a famous master’s student, and then rise smoothly through publishing.
Twenty years ago, talented writers like Yan Ge could still make their way through writing contests. Today, that is almost impossible as well.
