1. The whole poem of "flowers are not flowers when seen in the mist": flowers are not flowers when seen in the mist, and the moon is not the moon when seen in the water. Right and wrong are both true and false, and good and evil are both right and wrong.
2. "Looking at flowers in the fog, they are not flowers" means: Looking at flowers in the fog, the flowers are not flowers. This sentence means that what you see in a hazy environment is not necessarily true.
3. An ancient poem about seeing flowers in the mist includes Bai Juyi's "Flowers Are Not Flowers": Flowers are not flowers, mist is not mist. It comes in the middle of the night and goes away at dawn. How long does it take for you to feel like a spring dream? Going like a cloud in the morning, nowhere to be found.
