Elementary school just needs to lay a good foundation.
Learning English is not a bad thing, but parents can decide whether primary school students should enroll in English training classes according to their hobbies and actual situation. Most parents enroll their children in training classes mainly because of fierce competition. Other children go to cram schools, but their own children don't, for fear that they can't keep up with the learning progress, or they want to lay a good foundation for their children in English.
