There were many reasons why Chinese traditional festivals had gradually faded away. Some of them might include: 1. Rapid development of urban and modern society: With the acceleration of urban development, people's lifestyle, values, and cultural traditions are also constantly changing. Many traditional festivals have gradually lost their original meaning. People are no longer willing to spend time and energy to celebrate these festivals. 2. The lack of cultural content: Although Chinese traditional festivals have rich cultural content and historical origins, in modern society, many people may not understand the history, cultural background and celebration methods of these festivals, and they lack the corresponding inheritance and promotion. 3. Conflict with Western culture: In some cultures, there are differences between Chinese traditional festivals and Western culture, such as the way of celebration and food selection. This difference could lead to misunderstandings and confusion, limiting some traditional festivals. The popularity of foreign festivals in China could be due to a variety of factors. Some of them might include: 1. Cultural exchange: With the acceleration of the process of the global economy, cultural exchanges between China and other countries have become increasingly frequent. Some foreign festivals are more popular in the Chinese cultural circle because of their similarities in culture, history, and tradition, which are more easily accepted and understood by the Chinese audience. 2. Commercial interests: Some foreign festivals such as Christmas and Valentine's Day have similar consumption scenes and market demands as Chinese traditional festivals such as the Spring Festival and the Mid-Autumn Festival. Therefore, some merchants and enterprises would actively promote and organize these foreign festivals in order to expand their business and market. 3. Cultural identity: For some people, foreign festivals can also be a manifestation of cultural identity. With the continuous development of Chinese society, more and more people began to pay attention to their own cultural traditions and history, and the celebration of traditional festivals gradually became more enthusiastic.
