Display imageFrench tourists are attracted to caged singing katydids on sale yesterday at Shanghai's Yuyuan Garden. A 17-day midsummer night market festival, featuring old Shanghai's alley culture, opened last night at the city's famous tourist spot. Storytelling, outdoor movies, stands selling popsicles, chess games, rickshaws and caged katydids bring both overseastourists and Shanghai locals back to the evocation of old times on a summer night.
