How to understand "there are unexpected storms in the sky, unexpected storms in the earth, beautiful things and skillful work, and then the combination of these four can be good"

"Sometimes, the weather is lively, the materials are beautiful, and the workmanship is skillful, and then the combination of the four can be good." That is, the weather is limited by the season, the land is limited by the climate, the craftsmen are clumsy, and the materials are good and bad. These four are best combined.

This sentence comes from China's earliest design work-Flower King Gong Ji, which emphasizes that everything should be designed from the overall system of nature and times. "Earth" refers to the objective conditions of nature, while "beauty of materials" and "ingenuity of works" emphasize the subjective factors of the subject. ?

This is a systematic view of creation, which means that the creation should adapt to the weather and local atmosphere, with good materials and exquisite craftsmanship. Only by combining these four conditions can we make excellent utensils.

It can also be said that when making utensils, we should also choose the most suitable labor time according to its characteristics and requirements, so that the utensils made are excellent. "Good weather" and "majestic" refer to the objective conditions of nature, while "exquisite materials" and "exquisite craftsmanship" are the subjective factors that emphasize the subject.
