Why do Chinese people like to celebrate foreign festivals and ignore traditional Chinese festivals?

It feels like a trend that people are gradually losing interest in their traditional festivals and even forgetting about them, just like everyone is desperately trying to memorize words, but few people, who are dedicated to learning the Chinese language to memorize the dictionary, and even unwilling to change the misspelled words, feel that this is a kind of abandonment of the Chinese culture, which makes people feel sad, and then again, the majority of the traditional Chinese festivals are more serious and have a specific meaning, which is why they are so important to the Chinese people. Modern young people like novelty things, for the festival more concerned about is easy, and over the foreign holidays, self-conscious, how to amusement seems to be all right, such as Valentine's Day, Christmas and so on, but if you take the Qingming Festival as Valentine's Day to pass, it will feel particularly strange.
