One day, a nationally renowned English tutor boasted in class: "With my expertise, there's no idiom I don't know. Even Chinese idioms can't stump me!"
The students then began to challenge him.
Student A: "People mountain people sea!"
Teacher: "Easy. 'A sea of people' (人山人海)."
Student B: "Three heart two meaning!"
Teacher: "Simple. 'To be of two minds' (三心二意)."
Student C: "Look through autumn water!"
Teacher: "Can't fool me. 'To gaze anxiously till one's eyes are worn out' (望穿秋水)."
Student D: "Blue who say and the who's!"
The teacher was stumped. "Hmm... well... I think..." (After ten minutes) He admitted sheepishly, "You've really got me. What does that mean?"
Student D said triumphantly, "Ha! It's 'Nothing ventured, nothing gained' (不入虎穴，焉得虎子)!"
