📖 Meaning
To be extremely familiar with or thoroughly understand something. The idiom conveys that one knows a matter as clearly and easily as pointing at the palm of one's own hand. It describes complete mastery of a subject or situation.
📜 Origin Story
The idiom originates from the Analects (《论语·八佾》), a Confucian classic compiled during the Spring and Autumn period. When a ruler asked Confucius about the Di (褅) sacrificial rite, Confucius replied that he did not know it, then added that whoever truly understood it could govern the entire empire as easily as looking at this, pointing to his own palm. The image of pointing at one's palm came to symbolize effortless, complete understanding.
