欢（huan）
Name meaning
欢 (huan) means joy, delight and welcome. In names it should suggest social warmth and life energy, not shallow cheerfulness.
Practical naming use
欢 (huan) is a warm emotional character. It works when a name should feel welcoming, socially confident and open-hearted. The strongest reading is not constant happiness, but the ability to bring people together and make a shared space feel lighter. It needs a steady partner character so the full name is joyful without becoming childish.
Pair 欢 (huan) with peace, clarity or culture: 欢宁 (Huanning), 欢文 (Huanwen), 欢雅 (Huanya) or 欢然 (Huanran). Avoid pairing it with another excited word.
欢宁 (Huanning): Huan contributes joy, delight; Ning adds peaceful, settled.
