If you have just one day for a trip from Guangzhou, the watchtowers of Kaiping are a must-see. These multi-story towers, known as diaolous, served as flood refuges, forts, and residences from medieval to modern times, with the later ones blending Western and Chinese architectural styles. Visit the castle-like towers at Zili Village, explore the beautiful Liuyuan Garden, and experience the unique east-meets-west architecture of Chikan Old Town.
