Hello, kiss, I’m a girl too. First of all, you have to see if your little finger with the nail clipped can pass the position of the last joint line of the ring finger. The bass level is relatively large, especially for girls. It’s difficult to grasp it and you need to hold it often. Hands, try to see if you can hold the first four levels of G.
One for each thumb.
If you are looking for a more professional teacher, just find the piano store closest to your place. Bosses generally don’t ask amateurs to teach.
If you have small hands, you need to practice more, as mentioned above.
Also, if you have learned it before, you must be able to practice hard. Playing bass, especially girls’ hands, will cause blisters very easily. Don't give up, dear.
Personally, I recommend the Waiwei piano. It feels good in the hand and the body is relatively small, making it easier for girls to hold. You must also configure a speaker yourself.
If you still don’t understand, you can ask questions at any time.
