Several years ago, in many remote villages in Shaanxi, the number of residents fell so much that the villages were merged into one.
"The villages need to survive, but there are very few young people left because they all go to big cities to look for income opportunities. There are almost no women (in the villages)," he says.
Many women who go to the cities with their husbands either divorce or abandon them fearing the prospect of returning to the poor villages.
"In the past, Chinese literature either criticized or praised life in rural areas. But now it's impossible to do so," says Jia.
"Watching the situation arouses an unspeakable pain, just like the pain felt when a couple that has lost their only child sees a neighbor's child. It's a pain only the couple knows."
