Every January, my grandmother ground ink on stone and unrolled vermilion paper across the courtyard table. With a brush softened by decades of festival mornings, she composed seven-character verses — a couplet of antithetical lines pinned to the household door with flour paste, written to outlast the year.
The Grammar of Red and Ink
A spring couplet is not decoration — it is architecture made legible. The two vertical scrolls flanking the door mirror each other in grammatical function, tonal category, and meaning. Every noun opposes a noun; every rising tone meets a falling tone. The horizontal banner above, called héngpī, distills the couplet into four compact characters that read like a key turning in a lock.
