On the last day of the trip, we arranged a visit to the memorial hall in modern history. A very quiet memorial. Free visit with ID card. There are many precious old photographs, which record the events before and after the Xi'an Incident. There is Chiang Kai-shek's journey to Xi'an. Records of the relationship between the two parties before and after the incident. There were developments of the people and the army before and after the incident. The data are detailed and orderly. After seeing General Zhang Xueliang's Incident, he traveled around. When I was old, a picture made my heart palpitate. The old man stooped and looked across the sea from Taiwan to the mainland with a telescope.
