          Many parents worry about their children's use of e-books, such as the harmful effects on eyesight and over-reliance on modern technology.

          "Too many digital items surround our life. I only allow my 6-year-old boy to read in print. He can access more digital material when he's older."

          Zeng Yi, graphic designer in Tianjin

          "E-books can expose children to inappropriate content that is downloaded easily."

          Liang Yonghao, doctor in Quanzhou, Fujian province

          "Children can be quickly addicted to digital books, which can cause health problems such as those related to the eyes and neck. I prefer printed books for my daughter."

          Wang Bo, engineer in Changchun, Jilin province

          Hot topic

          "I think printed books promote deep reading and active learning for children. Going to bookstores was a weekly routine for my girl in primary school."
