About an hour's stay in the museum, the first floor is the old photo exhibition of memory of Dalian that year. Slowly sense of the times, see the retro atmosphere of Dalian. Actually, as a post-90s generation, I can't feel so much about the 60.70.80's. Occasionally, I saw the pictures of 89 years, which overlap with the pictures I saw sometimes in my memory. There are many three generations of people in the museum, holding grandchildren and explaining what happened at that time. When I saw the pictures of Miss Sweet's explanation, no wonder my father always told me to remember Miss Sweet's explanation. He was educated from an early age. There happened to be an activity in the museum, and I signed up for it. I don't know how it turned out.
