It's interesting to see that western festivals have created fun scenarios for people, especially Gen Z in China. It possibly rooted from human's nature that over generations humanity is always looking for fun and happiness.
People can be more relaxed in those western festivals, especially Halloween provide Not-To-Be-Myself fun moments for people. They joined together in theme parks of Shanghai, or even streets, organized a self-organized parade. It is fun to watch and record those happy moments.
As for the future, who cares? Let's have fun!
