New York is one of the largest cities in the world. In the 21st century, it has also suffered the most. On September 11, 2001, his Gemini constellation, together with more than 3,000 elites, disappeared. Coming to the 911 Memorial Base is more about the past with a sense of respect and nostalgia. Seeing groups of children coming in and visiting the memorial hall, I think we should keep telling the next generation all these things, keep people on guard, and let the harm of terrorism to the world end at an early date.
