First of all, children of this age are more playful and don't like learning. So you should cultivate her interest in learning, such as buying more meaningful books and less comic books. Tell TA more about popular science, but make sure he understands. If you can't, you can also give TA a little reward, such as how many ancient poems and a pack of snacks you have memorized, but you must not promise anything too expensive and don't get into the habit of sending TA, otherwise you may ask for something too expensive in the future.
I think that's all. I'll talk if there is.
But don't push TA, don't be impatient, after all, TA is still young.
