Have you noticed an interesting application in the news recently? To meet students' need for a midday nap, the principal of a school in Shenzhen designed a folding nap bed scheme for the campus. The design works like this: long rows of Storage Cabinets are placed against three walls of the classroom, with folding beds stored inside them. At nap time, students move their desks to the middle of the classroom and pull the folding beds out of the cabinets to lie down and rest. It really is a clever and very practical design. Until now, my understanding of designs like this campus folding nap bed was limited to office use, and my impression of such beds was not good, because they meant overtime, late nights and deadline pressure, lying down for a short rest when you are exhausted. Compared with passively accepting that mode of rest, the classroom nap solution is far more considerate of people, and the measure genuinely improves efficiency: when students get proper rest, their learning efficiency is bound to rise. On the surface, folding nap beds entering schools is simply a principal with ideas who solved the problem of napping at school through practice. Fundamentally, however, the essence of the matter is that the principal's action fully embodies a spirit of service and innovation, a capability that benefits students and aligns closely with the school's core purpose, achieving a good result in a positive and people-centered way. It is well worth learning from.
