The女 writing is clarified. The 2nd stroke撇 "can" stick out above the 3rd stroke 横。 though it should be "must". Anyway my daughter has learnt the correct version at least.

Anyone got corrected the chinese NU is written wrong when the 2nd stroke goes above the 3rd stroke? The teacher said this one 女is right coz the textbook says so . My husband is educated in china and i am singaporean have taken chinese at A level subject

We always understood it is a must to stick out
