The Chinese word "好好" is formed by duplicating the character "好", which itself is a compound character constructed from two pictorial components: 女 (woman) and 子 (child). Historically, this combination visually represented a woman with a child, evoking associations of goodness or beauty, which became the core meaning of "好". The reduplication simply repeats this character intact, creating a reinforced visual form that derives directly from the original character's composition without altering its fundamental structure.
