Why does China's traditional culture and art encounter a "cold current" in contemporary times?

I think it is because of the assimilation of the world. However, because western culture spreads more widely and has a greater influence than China's traditional culture, the effect of nature and assimilation is that China's traditional culture encounters a cold current. The same thing happened not only in China, but also in countries around us, such as South Korea, Japan and India, including the Arab world. However, there are still many people trying to preserve traditional culture, and there are still many people who love traditional culture and art. In such an environment, I think our traditional culture and art still have vitality. Although it does not occupy the peak, it still has its own place.
