Yushun struggles on the road: the Xi'an Incident Memorial Hall, also known as the "Double Twelve Incidents", is a historical event launched in Xi'an on December 12, 1936 by Zhang Xueliang and Yang Hucheng in order to persuade Chiang Kai-shek to change the established national policy of "to stop civil war and unite in resisting Japan". It's a pleasure to visit here.
