My Trip

Last summer, I had an unforgettable trip to Beijing with my family. We traveled by train and enjoyed the beautiful scenery along the way. When we arrived, the first place we visited was the Great Wall, which was truly majestic and awe-inspiring. We also explored other historical sites like the Forbidden City and Tiananmen Square, learning about China's rich history and culture.

Besides the historical landmarks, we also tasted delicious food in Beijing, such as Peking Duck and various dim sum. The trip was not only a journey through time but also a culinary adventure that left us with lasting memories.

Reflecting on this trip, I realize how much I learned and grew from the experience. Visiting places like the Great Wall has not only broadened my horizons but also instilled a sense of pride in me for my country's rich heritage. I will always treasure the memories of this trip and the lessons it taught me.
