顿开茅塞 is a Chinese idiom (chengyu) meaning “Suddenly become enlightened”. Have one's mind opened; suddenly understand a profound truth or principle. Literally, “Suddenly open the thatch-blocked mind”.
During the Warring States period, a man named Gaozi was inconsistent in his studies, often giving up halfway.
Mencius criticized him, saying, "A narrow path on a mountain, if frequently walked, will become a wide road. But if no one walks on it for a while, it will be overgrown and blocked by thatch. Your mind is similarly blocked by thatch, which prevents you from making progress."
