一呼百應

一呼百應 (yī hū bǎi yìng):

• 一 = "one"
• 呼 = "call"
• 百 = "hundred"
• 應 = "respond"

i.e. "when one has something to say, many come to listen":

• those who have clout will hold the loudspeaker
• those who do not will have a muffled mouth
• "not what one says, not even how one says it, but who says it"
• warning: take care not to lean too much on who says something
  • take heed what is said and if it stems from a ground truth
