In addition, it is recommended to find a professional physical education teacher you are familiar with and not to study in any profit-making institution in the swimming pool. They earn money mainly because the church is in charge, but they can't exercise. My son's swimming teacher is a retired middle school PE teacher. He loves sports and insists on swimming in winter. He brought all his acquaintances, children, college students and adults, charged a nominal tuition fee, and went to 200 yuan only one summer vacation. Money is not important. The key is that he is careful and strict. He teaches in the reservoir every year. As long as it doesn't thunder, he will go in the storm. As long as he doesn't go on time, he will kill you the next day, which is very exercise. He also lets you pull strength according to your study every day, and won't let you go back if you finish it, which is good for your child's growth and exercise. He also "promoted" those who learned well to assistant coaches, studied in groups, pulled strength, and recommended those who learned well to compete in other places.
My son started school at the age of three and a half. He has studied for three summers. Now that he is seven years old, he will continue to exercise with him this year. At the end of last summer vacation, my son had crossed the Yangtze River at Wuhan Yangtze River Bridge. At that time, there were passing ships on the river, and there was a whirlpool on the water. The children were a little scared, but they persisted. At that time, only we accompanied them, without any help, and it was impossible to study in the swimming pool.
