Nowadays, more and more young Vietnamese people celebrate festivals such as Christmas and Halloween. Some people think there is nothing wrong with this while others are worried about the influence of foreign cultures. In my opinion, celebrating world festivals has more positive than negative impact on young Vietnamese. Firstly, festivals are a great way to understand a nation's culture. Taking part in celebrations can help young people learn more about other people's traditions and customs. For example, Christmas is a typical holiday in many foreign countries, so when joining the festivities, young people can learn about its origin and history, the tradition of decorating one's home and getting presents for family and close friends, and putting them under the Christmas tree. Secondly, festivals are special events that help bring fun, happiness, and joy to young people's lives. They give an opportunity for young people to relax and spend enjoyable time with their friends and family. People can enjoy the festive spirit by watching performances, dressing up, and eating festive food. Finally, it cannot be denied that world festivals also encourage extracurricular activities at schools. Organising special events every year, such as Halloween parties or Christmas fairs, encourages students to discover interesting things about the festivals, socialise with friends from other cultures, or create their own performances. In conclusion, I firmly believe that celebrating world festivals in Viet Nam does more good than harm to young people. They can have fun, broaden their cultural knowledge, and enjoy their school life more.
