Ex: English studies would not be complete without Aesop Fables. Learning the stories is the only way you can understand common phrases / idioms like "sour grapes".
Chinese studies includes Romance of the Three Kingdoms. A Chinese Friend of mine explained the meaning of the phrase "Pour the oil", based on some Sima-Yi / Zhuge Liang story from RotTK. (Which IIRC, means something along the lines of "I'm not going to be a sore loser about this")
Japanese studies include something about an impenetrable shield and the all-penetrating spear, which apparently is the root word for contradict. Using "Google Translate" on this one, "矛盾" translates into "Contradict". But "矛" means Spear, and "盾" means shield.
So a dumb translation would translate "矛盾" into "SpearShield", which is nonsense. But the meaning is "To Contradict".
