Shuimu Palace is a forest park at the foot of Woyun Shan, 3.5 kilometres north-west of the main urban area of Zhangjiakou, Hebei Province, China, and is a key cultural relic protection unit of Zhangjiakou. It was built in the forty-seventh year of the Qianlong reign of the Qing dynasty (AD 1782) and houses a shrine to the Shuimu Niangniang. Legend has it that when the Queen Mother of the West passed north through Wolong Shan she felt thirsty but found no water to drink nearby, so she drew a line on the ground and made a spring, and Shuimu Palace was later built over the spring. During the War of Resistance Against Japan, the headquarters of General Feng Yuxiang's Chahar People's Anti-Japanese Allied Army was established in the White Dragon Cave within Shuimu Palace. Ji Hongchang, commander-in-chief of the northern front of the Anti-Japanese Allied Army, also directed the anti-Japanese movement here, and a memorial hall to the martyr Ji Hongchang and other buildings stand on the site.
