Built around 1869, the Mandarin’s House, with over 60 rooms, was the ancestral home of Zheng Guanying, an influential author-merchant whose readers included emperors, Dr Sun Yatsen and Chairman Mao. The compound features a moon gate, tranquil courtyards, exquisite rooms and a main hall with French windows, all arranged in that labyrinthine style typical of certain Chinese period buildings. There are guided tours in Cantonese on weekend afternoons.
