China Has a Saying: Speak Only Three Parts — Never Give Away Your Whole Heart

In ancient China, there was a saying: speak only three parts of what you know, and never give away your whole heart. This was not a lesson in deception. It was hard-won wisdom from a society where information, once spoken, could never be taken back. What you said to one person today might reach ten people by tomorrow — filtered, reshaped, and returned to you in a form you no longer recognised. This episode looks at why holding back was not coldness, but clarity. From the fatal mistake of Han dynasty official Yang Xiu, who said too much to the wrong person, to the unspoken rules of the imperial court — and what this centuries-old saying still tells us about the weight of words.
