A mother in Xi'an, capital of Shaanxi province, built a tower with about 10,000 books as a reminder to parents not to place too much learning pressure on their children.

Li Yuling, who runs a small cafe near a middle school where her son is a seventh-grader, spent more than a month building the tower next to a stairway to the second floor of the shop.

"My assistant and I made the tower with about 10,000 books, all secondhand teaching materials and learning guidance books," Li said.
