The wedding candy box was printed with the double-happiness symbol.
Tips
culture
Two 喜 ('joy') side by side, read once as 囍 or spoken as 双喜 ('double happiness'). It is cut from red paper and pasted everywhere at Chinese weddings to wish the couple shared joy.
Right 喜 mirrors the left one exactly. The symmetry is the whole point: a single, unsplittable wish for double joy, used only as a decorative wedding glyph.
No stroke data for 囍; the glyph shown is your device font, so component strokes can't be highlighted.
