By Sound
Mason (MAY-suhn) splits cleanly into two sounds Mandarin can approximate well: 迈 or 麦 for the opening, and 森 — already familiar from names like Jason — for the close.
By Meaning
Mason started as an occupational surname, someone who builds with stone, and carries that sense of solid, hands-on craftsmanship into its use as a first name. It's a name about foundations.
By Spirit
Masons tend to project dependable, unpretentious strength — not flashy, but the person you'd trust to actually build the thing. Quiet capability over showmanship.
