As globalization accelerates, the traditional customs and celebrations of many nations are gradually being supplanted by internationalized commercial holidays. Some argue that this cultural convergence helps foster global identity and exchange, while opponents worry that it will lead to the erosion of local distinctiveness and the weakening of values passed down through generations. In the face of this trend, should local societies prioritize embracing cultural fusion, or should they go to great lengths to preserve their unique traditions? Please articulate your stance, providing reasons and concrete examples to support your viewpoint.
