Girls of this age (12 years old) like to study the Book of Changes. Why (see detailed description)?

I think you should learn your lessons well first, so as not to worry your family and delay your study. As for the Book of Changes, if you really want to learn it, you need to find a professional master to teach it when you are an adult. Because there is no real person to explain it to you, it is difficult for you to read the Book of Changes yourself, and the contents of the Book of Changes sold in the market are not comprehensive.
