The young monk symbolizes feng shui.
The general meaning is don't look, don't listen, don't say, don't do anything that doesn't conform to the ceremony. This is to show Confucius' warning with four young monks of different shapes.
The squatting posture of four young monks looks naive: the first one covers his ears, the second one supports his cheeks, the third one covers his eyes and the fourth one covers his mouth. It vividly shows the cautious, kind and indisputable life character.
The meaning behind "Four Monks" comes from The Analects of Confucius Yan Yuan. Content excerpt: Confucius said: "see no evil, don't listen to indecent assault, don't say indecent assault, and don't move if you are indecent assault." Yan Yuan said, "Although I am not sensitive, please talk to me."
Interpretation of vernacular: Confucius said: "Those who are impolite don't watch, those who are impolite don't listen, those who are impolite don't say, and those who are impolite don't do it." Yan Yuan said, "I am stupid, but I still do as you say."
