Our inner feelings don't come out of thin air, only when they are touched by the external environment. For example, the environment has all kinds of uneven facts around us. Only when we know these facts can we have a feeling of hatred.
Besides, the outside world will not rush into our consciousness, and only when it touches our feelings will we really pay attention to it. For example, the more attractive the scenery we enjoy, the more detailed we know, and the more benefits we can identify. As for the ordinary scenery, although it is arranged around us, we don't pay special attention to it, as if there is no scenery there.
According to the above, emotions are closely related to the environment. Poets often seize everything as the material of his poems at the moment when emotions are related to the environment-not only poems, but also paintings by painters and sculptures by sculptors.
