Since its opening on April 4, 1973, the towering towers of the World Trade Center have become the landmarks of New York "North Tower" and "South Tower" at that time, the tallest buildings in the world surpassed those of the Empire State Building. After the terrorist attacks on the twin towers on September 11, 2001, more than 3,000 elite survivors were unfortunately destroyed and the World Trade Center was destroyed. Many controversies over who owns the site and what to build here have delayed the reconstruction for many years. The final planning decision was to build a memorial in the place where the twin towers were and six new skyscrapers around them. Two years ago, when we visited the entrance around 6 p.m., or was it the entrance of the director of the Dragon who was fortunate to have the VIP from his daughter, we quickly got involved. Through security inspection, we visited the whole Memorial Hall in a very solemn and magnificent picture. The broken walls, broken cars and broken flags seemed to restore the scene of the disaster. We could not help but lament the small life of the world and mourn for the dead. We sincerely hope that there will be no more war and peace in the future.
