Located 35 kilometers northwest of Yinchuan City, Zhenbeibu China West Film Studio (镇北堡西部影城) sits on the site of two ancient castle relics built during the Ming and Qing dynasties to defend against the invasion of tribes from the north side of Helan Mountain. One of the three biggest film studios in China, its location can add sense of desolation and sadness to movies. [China.org.cn]
