"Reducing the burden" for children's schoolbags has always been a topic of public concern. Do you know that the weight of schoolbags is the most appropriate? An article in the American "Life" magazine pointed out that the weight of the backpack should not exceed 10% of the weight of the backpacker. The American Physical Therapy Association conducted a study on 9-grade students that overweight backpacks and incorrect backpacking methods can cause back injuries and muscle fatigue in teenagers. Researcher Mary Ann Wilmarth said that a child's backpack will cause kyphosis, scoliosis, leaning forward or twisting. At the same time, the muscles may become fatigued due to extreme tension, and the neck, shoulders and back are easily injured. If the weight of the schoolbag exceeds 10%-15% of the weight of the backpacker, the damage to the body will increase exponentially. Therefore, she recommends that the weight of the backpack should be controlled below 10% of the weight of the backpacker. Experts believe that the weight of children's schoolbags should be around 2.5 kg! The American Physical Therapy Association recommends that children try to use backpacks on shoulders. Experts say that the double-shoulder style can disperse the weight of the backpack, thereby reducing the possibility of body distortion. In addition, the trolley schoolbag is a good choice for younger students, because American students in the upper grades need to go up and down to change classrooms, while the lower grades do not have these troubles. In addition, it is also very important to place the items in the schoolbag reasonably. The heaviest items are placed close to the back.

Regular brand holders will award the brand or animation image to a more regular manufacturer for the production and sale of animation derivatives.
