It's only natural that Chen Xi's remark about how it's impossible to finish learning so little material, even after he intentionally reduced the amount, has been widely circulated among the aristocratic families, often used to crush the self-confidence of their younger generation.
Anyway, it's not uncommon for aristocratic families to obtain the academy's textbooks for study. Two books serve as moral education and two as personal conduct education, which is indeed very suitable. However, the older generations of aristocratic families feel that it's only possible to finish, understand, and comprehend these books around the age of thirty.
As for Chen Xi using books on self-cultivation and personal conduct as introductory texts, aristocratic families can only agree with what Lub Su said, thinking not everyone is like him, able to devour such books as introductory materials.
