Rǔshān

Rushan occupies a stretch of the southern Jiaodong coast, where bays and low hills meet the sea. On a peninsula nearby, the Ming established the Haiyang military post at a place once called Shagouzhai. Its garrison formed part of the coastal defences against maritime raiders. Military households from other parts of China settled in the district, and their descendants remained after the post was abolished. The name Haiyangsuo passed from the garrison to the settlement that grew around it.
