As globalization continues to deepen, traditional festivals in many countries are increasingly being reshaped by commercialization, while younger generations seem more drawn to internationalized ways of celebration.

Or, to maintain cultural vitality, is adapting to the trends of the times inevitable? Please state your position and justify it with specific cultural examples.
