Write a composition about a day trip to the estuary.

That day, the sun was particularly bright. This must be a gift from Father Sun to the children. On this sunny day, I came to the composition class with a happy mood-to participate in the activities of collecting wind in Hekou town on the border between China and North Korea. Hekou Town is a beautiful town by the Yalu River. He has beautiful scenery, beautiful environment and peach trees everywhere, which can be described as pink and green, birds and flowers. Unfortunately, the peach blossoms have withered, but the fruits are numerous and worth appreciating. We came to the Yalu River and saw the famous broken bridge on the Green River. The bridge was bombed by American planes during the War to Resist US Aggression and Aid Korea, and now it has become a witness to tourist attractions and history. On the head of the broken bridge, there are statues of heroes emerging from the Korean battlefield, such as Commander-in-Chief Peng and Mao Huang Jiguang Qiu. This made me respect them, and also reminded me of the story my grandfather told to resist US aggression and aid Korea. At that time, Dandong was a famous hero city. Under the indiscriminate bombing of the US plane, it stood tall and persevered, and completed the task of resisting US aggression and aiding Korea. The estuary was the outpost. It is of great significance to come here today to pay tribute to the heroes and remember their heroic deeds. Today, our country is strong, and the invaders will never dare to invade us again. We live in a happy era, but we must firmly remember the teachings of Grandpa Deng, and development is the last word. How can we develop? You must have excellent quality, strong physique and rich scientific and cultural knowledge in order to become a talent for the development of the motherland. For the motherland, let's study hard and make progress every day!
