Kindergarten life is dominated by games, with no schoolwork pressure and no fixed textbooks. Many times activities are carried out according to children's interests, so children feel "fun". Primary school life is dominated by classes, with fixed textbooks and schedules, and it is difficult for children's will to transfer activities. It is also "not fun". Of course, if you meet a good teacher, primary school life will still be "fun". When I went to primary school, several children around me said that they liked primary school life very much and could know a lot. They think primary school life is also "interesting".
