Origin Story
话说唐朝时期，有个叫李白的诗人，才华横溢，但性格傲慢，不拘小节。有一次，他在长安参加一场盛大的宴会，席间，他喝得酩酊大醉，竟然当众脱鞋，在席上狂舞，还大声喧哗，旁若无人。在场的人都对他这种行为感到震惊，纷纷指责他的粗鲁无礼。然而，李白对此却毫不在意，依然我行我素，甚至还恬不知耻地辩解说自己是为了表达诗兴。众人被他这种厚颜无耻的行径给气笑了，但李白的名气太大，也没人敢说什么。后来，人们用“恬不知耻”来形容那些不知羞耻的人。
During the Tang Dynasty, there was a famous poet named Li Bai, who was extremely talented but also arrogant and undisciplined. Once, he attended a grand banquet in Chang'an, where he got drunk, took off his shoes, danced wildly, and shouted loudly, ignoring everyone around him. The other guests were shocked and criticized him for his rude behavior. However, Li Bai didn't care and even shamelessly justified his actions by saying he was expressing his poetic inspiration. People were amused by his shameless behavior, but no one dared to say anything because Li Bai was very famous. Since then, the expression "恬不知耻" has been used to describe people who are shameless.
