Her father is very proud, and badgers his brother into helping him shift into a position where he can play his guqin for her. 

!!! Pretty!!!

He can't do it as often as he'd like, because Brother is only so badgerable when it comes to being careful of his wounds, but he does it as often as he can. He continues listening to everything she says with rapt attention; he puts all her art on the walls and hides her stories when he's not reading them so that a healer who barges in unannounced won't realize she can write readably and inform her teachers. 

He doles out stories of her other father when she asks for them. The story of how he acted up in class and was assigned to copy the rules for punishment, with Wangji supervising, and he constantly prodded Wangji for attention instead of doing his assigned copying, even drawing a picture of Wangji with a flower in his hair. (He kept the picture. He tells A-Yuan where to find it, so she can see.) The story of how he got in a fight with another student because said student was being mean to his absent sister, and was ultimately expelled for punching him in the face. 

The story of how he gave Wangji the first two bunnies as a goodbye present. 

She loves the stories. She's delighted by the picture of daddy with a flower in his hair, and quasi-secretly figures out how to make an origami flower like the one other daddy drew, so daddy can always have flowers. Other daddy defending his sister is good, too.

Learning the bunnies are from other daddy makes her like them even more.

She wants to know everything about all the songs, too!

This one is "Inquiry." This one is "Rest." This one is "Clarity." He teaches her their uses in cultivation. Others have more mundane origins. 

She likes all the songs! Though songs that do cool magic things are really really interesting.

(He does not tell her that he tries to call her other father's spirit when he plays Inquiry, and he has never responded. She doesn't need that.) 

Her teachers continue to praise her progress in reading, martial arts, and meditation and despair over her handwriting. 

They begin formally learning the three thousand and some odd rules of the Lan Sect.

The rules are so boring. She mostly just ignores them - unless someone tries really hard to get her to obey all the rules.

If her teachers catch her breaking the rules they will definitely try to get her to stop that! In the form of assigning copying the rules as punishment. 

That's a really silly punishment and not actually all that effective on her. She does scribble for a bit, sometimes, but her handwriting's so atrocious it's impossible to tell if she's drawing or copying.

As long as she has the right number of characters she can get away with this with no more than the typical clucking over her penmanship.

She mostly has the right number of characters. (She's very annoyed about the copying, and complains about it to daddy.)

Her daddy pets her and tells her she's following a tradition started by her other father of doing other things when you are supposed to be copying the rules and has she considered humorous subversions.

That sounds fun!

One of the other children also frequently  has copying. His handwriting is almost as bad as hers.

She's been having trouble making friends properly. That deters her zero from smiling at the other kid and trying to chatter with him whenever they both have copying!

The teacher supervising them attempts to shush them but by the third time the two of them have copying together he's given up as long as they chatter quietly and don't stop writing. 

"I don't know why the teachers always say your handwriting's bad, I think it's really pretty," he says.

"Thanks! They can't read it, so they think it's no good."

"Can you read it?"

"Yeah. Just fine."

"Why can't they?"

"I think they're not looking if it's too weird."

"Can I see?"

"Yeah!" She pushes her sheet over.

The boy studies the characters but hasn't worked out what any of them are besides "pretty" by the time the teacher scolds her to go back to writing instead of showing off what she's already written.
