My child used to be like this. He did his homework until 11 o'clock every day and was serious about not playing, but his grades were not good. Later, he accidentally saw an article by Teacher Shi Jiaqi and asked Teacher Shi to identify the child's name. , finally found the source of the problem. Teacher Shi once said that if the surname is broken, it will have an impact on studying; if the yang edge of the last character of the name is broken, studying will definitely be bad. All my children have it, but the middle character is pretty good, so they have good personalities. Later, I changed my name, and the problem of the first surname was resolved. Over the past year, studying has become much easier, and I can sleep well every day. It is recommended that you ask Teacher Shi to identify your child's name to see if the problem lies in the name. If there is a problem with the name, Teacher Shi will change it to a good name that is easy to learn. Don't go looking for those horoscope names, it's useless.
