Apliu Street and its surrounding lanes form Hong Kong's largest flea and electronics market, running daily from mid-morning until evening in the heart of Sham Shui Po. The stalls sell second-hand cameras, vintage phones, military surplus, components and cables, old watches, and hardware obsolete everywhere else. It is the kind of market that rewards patient browsing rather than shopping with a list.
The adjacent Nam Cheong Street has more specialist electronics shops. Sham Shui Po MTR puts you at the eastern end of the market strip; walk west from exit A2.
