The so-called ten dangerous places in China refer to Haiyan in North Xinqiao, Sun Yat-sen Mausoleum in Nanjing in North New Territories, screw-cap unlit alley in Yangzhou, incense burner modeling in Shenzhen University, Kathy Church in Tianjin, Shandong Provincial Museum, hang lung plaza, Yongfangtang in Sun Yat-sen University and liberal arts building in Sun Yat-sen University.
These places do exist, but all kinds of rumors come from unofficial history, legends and folk rumors. And the authenticity is not high.
