### 3c
Last summer vacation, I had an unforgettable holiday in Sanya.
As soon as I arrived there, the beautiful beach caught my eyes. The blue sea stretched as far as I could see, and the soft white sand felt comfortable under my feet. I couldn't wait to rush into the sea. Swimming in the warm seawater was such a delightful experience. When I got tired, I lay on the beach, enjoying the sunshine and the sound of the waves.
I also spent time building sandcastles with other kids. We used shells and stones to decorate our creations, laughing and having a great time together. In the evenings, my family and I would go to the local markets to try various delicious seafood, like grilled prawns and fresh fish.
Every moment there made me feel happy and relaxed. This holiday taught me that traveling not only allows me to enjoy beautiful scenery but also helps me make new friends and learn about different cultures. I realized how wonderful it is to explore the world and appreciate the beauty around us.
