Yucheng Postal Stop, Historical postal museum in Gaoyou, China.

Yucheng Postal Stop is a courier station in Gaoyou, Jiangsu, on the east bank of the Grand Canal. Its 1.6-hectare compound includes a three-storey drum tower, the Huanghua Hall (front hall) and the Zhujie Hall (back hall), with most buildings rebuilt in the Qing dynasty. It now serves as the Museum of Chinese Postal History.

The station was founded in 1375 during the Ming Dynasty and served as an important hub for couriers and boats. It survived several fires and damage, including a major fire in 1557, and was later rebuilt several times under the Qing Dynasty.

The building displays architectural features from the Ming and Qing periods that show how the postal system worked. Visitors can see how the spaces were arranged for daily work by couriers and officials.

The site sits conveniently along the Grand Canal and is easy to walk through at your own pace, taking time to visit different areas. It helps to wear comfortable shoes and arrive earlier in the day to see the rooms in good light.

The drum tower, the compound's tallest structure, carries plaques inscribed by figures such as historian Liu Chongri and diplomat Jiang Enzhu, including one reading "Placing Mail and Transmitting Orders". From its third storey visitors look out over the surrounding lanes of Gaoyou.
