Time Travel + Anti-Japanese War 1937, Nanjing, a woman who has read the city's archives, standing in 1937, knows the ending. A soldier sent away all the women and children in the city and turned back to guard the city wall. On the dock, she only said: Come back alive. He should: Yeah. The city is broken, some people die standing and some live on their knees.
Many years later, a photo came back to her from Nanjing - the person in the photo was her, with deep creases...
The fall of a city, the persistence of a group of people.
