The day before, the tour guide asked me if your children could understand the 911 Memorial Hall and would they like it. I said that it was not a matter of liking or disliking it. Death itself was an education. In fact, today the children told me that this was their most shocking education about life. The original two buildings are now two huge holes, the flow of water, mourning endlessly. Inside the museum, the whole event of September 11 was silently told by the burned fire truck, the heavily deformed steel pipe, the wreckage of the life passage, and the pillars full of mourning for the victims. No day shall erase you from the memory of the time. Time will never erase you from the memory. These words are all made from the remains of two World Trade Center buildings. The author believes that even the remains of the ruins can still bring hope and beauty. The children said that they were shocked and tragic, but they were also touched by the stories of people in many disasters, cherishing peace and life. I think they did have one of the most wonderful life education courses.
