On the “Four Classics and Five Scriptures” (sishu wujing 四书五经), I’ve already quoted the fine saying (At home with a master Daoist, n.1)
Confucius, Mencius, various dumpling shapes, I’ve studied them all!”
老装孙子 laozhuang sunzi,
which is a common expression for “always playing the fool” (cf. the more recent, and rather different, zhuang B). But it can also be handily pressed into service when satirizing one’s supposed education in the classics, subtly revising the zhuang character to 庄—the Daoist sages Laozi and Zhuangzi (Lao–Zhuang), followed by the ancient military strategist Sunzi.
