档案The Vault · a record of the only place

A Shanxi man, Wang Ruifu, opens a plain wine shop in a lane by the Qianmen gate. No sign worth painting — only a broken gourd hung at the door, and a lamp kept lit later than its neighbours'. No image of that first year exists; this is drawn from the record.

On a snowbound New Year's Eve, a traveller in plain clothes finds the one door still glowing and asks the shop its name. It has none. "On a night like this," he says, "in all the capital, this is the only place." The traveller was the Qianlong Emperor; the plaque came soon after — three characters in his own hand.

The first century the shop could be photographed. Glass-plate and silver prints of the Qianmen frontage, the crowded room, the hand-cut sign — most are still in private hands and municipal archives. These plates hold their places until the originals arrive.

Under the public–private partnership the house moves to larger rooms just north of Xianyukou and reopens. The paper trail — the new frontage, a staff portrait, an early printed menu — belongs to living memory, and to the drawers of those who kept it.

Duyichu's shaomai craft is inscribed as National Intangible Cultural Heritage. The modern record — the certificate, the masters at work, the twenty-four folds in close-up — is the easiest to gather, and the most alive. It joins the archive as the arc completes.

The lamp is still lit on the same Qianmen street. Under the Bianyifang group, the folds are still counted to twenty-four — and one day this plate, too, becomes a photograph in someone's drawer.
