Interpreting meaning is a metaphor for things that have no eyebrows and no end.
Originated from Zen. "Continued Lamp Record" Volume 29: "Ask who it is and can't say anything." It means don't show signs. Later, "there is no ambiguity in the eight characters" and "there is no ambiguity in the eight characters", indicating that things have not yet been sorted out. For example, Episode 29 of Heroes of Children: "Otherwise, my sister just thought, I haven't read a word, so I dare to draw my sister and him on a picture rashly?" Another example is Lao She's Four Generations under One Family: "Although the story of saving Mr. Qian has not been forgotten, there is hope at last."
