Ask for a famous saying ~ It seems to belong to a scholar in China. This is a parallelism sentence. I don't remember the first sentence, and the last sentence probably means that the rumor ends in silence. Said by: Xunzi's outline: "Flowing pills stop at Ouwan, and rumors stop at wise men." Ouwan: earthenware, speaking of concave land. The rolling ball will stop when it falls into the depression, and the rumor will subside when it reaches the wise man. If there is no basis, it cannot be passed on to people with brains. Describing rumors can't stand analysis.
