The last men who can still bend light by hand on Shanghai Street
Three benders remain in Kowloon. When their torches cool, the recipe for a glowing pink tube cools with them.
I spent two weeks last winter sitting on an overturned crate in a Yau Ma Tei workshop that smells of singed glass and propane. Master Tsang heats a four-foot length of clear tube until it sags, then pulls it into the shape of the character for "wine" in one continuous breath. He does not measure. The bend lives in his wrist.
「火太急，玻璃就裂。要等它軟，唔可以迫。」
A trade lit from the inside
The colour is not paint. Pink comes from neon gas pushed through tube coated in rare-earth phosphor; the hot green is argon with a trace of mercury. Tsang learned the gas ratios from his father in 1971, scribbled on the back of a cigarette carton he still keeps taped above the bench. No one wrote them down properly, and no school in the city teaches them now.
By 2023 the building authority had ordered down most of the cantilevered signs that once hung four storeys over the wet road, ruled unsafe. The torches that survive work mostly for collectors and films. Tsang shrugs at that. "A sign that nobody walks under," he says, "is just furniture."
