The method of rejecting early education courses can be said to be that the children's time schedule is not open. I got a call from the training institution of early education courses. If I don't want to attend, I can say that my children's courses are full and I really don't have time to attend other trainings. You also need to leave some space for your children. You can also say that you have participated in a training institution similar to incoming calls, and you can generally refuse. .
