On the afternoon of December 21st, our class held a winter solstice celebration in the school cafeteria, with dumplings as the main dish. The purpose of the activity was to promote traditional Chinese culture and enhance the sense of unity among classmates.

During the event, we all gathered around the table, kneaded the dough, and wrapped the fillings together. Everyone was fully engaged and enjoyed the fun of making dumplings. We also shared our own stories and experiences related to the winter solstice festival.

The activity had a positive impact on our class. It not only enriched our knowledge of Chinese culture, but also enhanced our communication and cooperation skills. Moreover, it strengthened our sense of belonging to the class and school, and promoted the harmonious development of the whole class.
