The exact literal meaning of hèhè is not fully clear, yet judging from the context and sound-meaning, it resembles wailing and scolding, carrying the sense of strict constraint.
Nine in the Third Place is at the top of the inner trigram, presiding over the governance of the interior. Being a yang line occupying a firm place without centrality, though it attains correctness, it exceeds in firmness.
Governing the interior with excessive firmness errs on the side of severe strictness; hence the household members are sternly disciplined and scowling.
Yet managing a home with excessive strictness cannot be without friction; hence there is bound to be regret over severe harshness. Affection among kin tends to overcome severity, and when severity is excessive, regret follows.
Though there is regret over harshness and it fails to strike the balance between leniency and strictness, the household order is nonetheless maintained with solemn discipline, and people's hearts are filled with reverent awe; this remains good fortune for the family.
But if women and children giggle and chatter, it will end in shame and distress. In the hexagram there is no literal image of giggling; it is spoken in contrast to hèhè, meaning that rather than erring on the side of lax indulgence, it is better to err on the side of strictness.
Giggling and chattering means laughter and merriment without restraint. Self-indulgence without restraint ultimately ruins the family, bringing shame and regret.
An excess of strict discipline, though inevitably grating against human feelings, establishes standards and rectifies moral relations, which is where love and duty truly reside.
Unbridled giggling and frivolity, however, is the very source from which standards are abandoned and moral order is thrown into chaos—how could it preserve its household? In extreme cases, unrestrained giggling leads to the misfortune of family ruin.
It merely says "regret" because what is deeply regrettable will eventually culminate in misfortune, though one does not speak of misfortune precipitously.
