Hang Thiec is the street of tinsmiths. The craftsmen originally produced small tin cone-shaped tips which were used to preserve the shape of the traditional conical hats. A neighboring street, Hang Non, made the hats, and both streets comprised the Yen No hamlet.
Hang Thiec Street also produced oil lamps, candle sticks, and opium boxes. Tin shops sold mirrors, which they still do today, along with sheet metal, zinc, and glass. The street echoes busily with the clanging of hammers against the sheet metal. Workers spread out on the sidewalk shaping metal storage boxes and other objects to custom order.
