From this, I'm getting that the author chose to give each of the Su children specal talents - Chong (martial arts), Hua (scholar/knowledge), Xiaolu (medicine & business - she can see opportunities where they can't because of her transmigration) and it seems that Xiaoling will be next due to caring personality (cooking especially medical cuisine). All of them are literate. One thing is definite Sanlang/Zhao children will definitely be successful in the future and make them proud.
