Why is traditional literature and art the torch of national spirit? Can some decadent traditional literature and art become torches?

not in principle. However, most people in China don't have their own sense of cultural belonging now, so the only cultural carrier left is almost entrusted with the cultural feelings of 1.3 billion China people in China. You can try to feel this mentality. Therefore, even some rotten dross will be used by quite a few people as national flagpoles. But the rotten will eventually disappear, and the dross will eventually be discarded. We, especially our generation, have realized this. Maybe twenty or thirty years, maybe even longer. After several generations, we will finally find the true sense of cultural belonging of our Chinese nation. At that time, it must be healthy and uplifting, which makes our generation feel gratified.
