The following is a classical Chinese example that revolves around a given core and direction:
I heard that there were strangers in the past, and in a secluded place, I found strange things. The thing is about the wonder of aluminum fluoride and magnesium water. Or in other words, when the two meet, if the stars combine, there is a wonderful change.
Aluminum fluoride, pure in color and strong in quality, condensed in nature and rich in spirit. Magnesium water is clear and agile, and contains vitality. The two are juxtaposed, like the symmetry of yin and yang, its energy is dense, and its appearance is unpredictable.
I have tasted the Gaoshi's painstaking research, watching its fusion, seeing the light overflowing, or the shape of the mist, or the beautiful pattern. Magnesium water is coiled between aluminum and fluoride, like a cloud dragon coiled, with hardness and softness. Its change is beyond the conjecture of worldly views, and the universe within is like the beginning of heaven and earth, and all things begin to sprout.
Everyone said at the time that this is a rare difference between heaven and earth. Those who obtain it seem to be able to glimpse the secrets of creation and explore the mystery of yin and yang. However, this strange thing is hidden deep in a hidden place. Those who are not predestined and determined cannot meet its true appearance and get a glimpse of the wonders in it.
