The four prefectures of Thanh Hoa province, Khe Sanh base and DNZ in Quang Tri, the Imperial Palace in Hue, and the Nam Hai Quan Ain Temple in the south. Black Pagoda Mountain and the Eye Temple in Tay Ninh, etc. Hopefully, there will be a new attraction in each province if DLC is released later. It would be even better if you could pronounce the words while typing, as this would help you learn Vietnamese....
