Family life has changed

Du Runlei, 40, associate professor of biology at Wuhan University

After receiving our doctorates in biology, my husband and I traveled to the United States for further study, and we had our first son there in 2007. Our second son was born in 2011 after we returned to take up teaching jobs at Wuhan University.

The arrival of our second boy changed the atmosphere in the family. The burden on both parents and children has become lighter, because the attention is no longer focused on just one child.
