The teaching at Chongwen Pavilion is different from privately teaching the three children. There, at least ten students are seated, including the heir apparent to the throne, and he can't possibly lecture only the Crown Prince on chapters four, five, and six, can he?
Speaking of which, when he taught the three children the Classic of Filial Piety back then, he merely skimmed through the second and third chapters, didn't explain much about the filial piety owed to emperor or feudal lords, largely focusing on the chapters afterward.
Zhuang Xun found himself a bit overwhelmed, realizing for the first time that teaching wasn't such an easy task, especially when this Crown Prince wasn't an ordinary prince, and his father wasn't a typical monarch either.
What to do? When teaching the chapter about the emperor, he couldn't possibly say to the Crown Prince, "Do not neglect your ancestors, and cultivate your virtue," could he?
