Stroll along the Xu River and step back into the golden age of ancient Wu Kingdom! As one of China's earliest man-made canals dug by Wu Zixu, this waterway whispers tales of Nanjing's millennium-old grain transport history. Willow-lined banks and arched stone bridges set the scene for a dreamy slow travel experience – when sunset paints the water with rippling gold against traditional houses, every frame looks like an ink-wash masterpiece.
