Well, personally, I think it's best to start learning in primary school and early in kindergarten, but it depends on whether a person has talent or interest in this field, otherwise it's useless to learn early. I'm also learning guzheng, which I started in the third grade of primary school. Now I have finished the eighth grade of junior high school. It is estimated that Grade 9 10 has little time to take the exam. I think it's best to start from grade 12. Junior high school is a little late. If you decide to go this way in the future, it's not too late.
I hope to adopt O(∩_∩)O~
