Shoulder bag is better than the lever
The best choice for a schoolbag is to choose a traditional double shoulder.
Some parents worry that the heavy schoolbag will bend the child's back, so they will buy a stylish and pull-up trolley bag for their children. Xia Yingpeng, chief physician of the Department of Spine 3 of Tianjin People's Hospital, reminded that the best choice for a schoolbag is the traditional double-Shoulder Bag. The trolley-type bag and the single-shoulder bag will also cause the child to squat and the shoulders are unevenly stressed. After that, the muscles are not balanced, but the back feels a little pain, and serious factors may also be the predisposing factors for scoliosis. It is recommended that children who have bought a trolley bag or a single shoulder bag should pay attention to the left and right hands alternately pulling the lever or the left and right shoulders alternately carrying the bag.
