The shops of the jewelers, who perform miracles of craftsmanship in gold fliagree and in jade, are especially interesting, the sensitive-fingered artisans working at benches set in the windows in full view of passersby. The meat and fish stalls, the apothecaries, the cobblers who work on the sidewalks, the lily and the bird vendors, the telephone exchange where Chinese girls operate the switchboard, the headquarters of the Six Companies, the Joss House and the Chinese theatre, spilled over into the Latin Quarter, are among the sights much written about by globe-trotting notetakers in the quarter.
