Second, let children know where their sitting posture is wrong, and then they will know how to correct it. Parents can take pictures of correct and wrong sitting positions and stick them on the wall. Third, write the correct writing posture into nursery rhymes and writing exercises, so that children can study hard. Fourth, encourage children to correct. For example, when the child is doing homework, accompany him for a period of time, and use a watch to record the time when the child supports the correct sitting posture. Starting from one minute and gradually extending, the effect will be better.
