When people talk about jade cultivation, the word "cultivation" not only tells us that jade is a living substance, but also contains a lot of knowledge. The maintenance of jade jewelry can be summarized as follows: the hardness of jade is very high, but it is easy to crack after collision.

The rockery has various landscaping functions, such as forming the main landscape or terrain skeleton of the garden, dividing and organizing the garden space, arranging the courtyard, revetment, slope protection, retaining soil, and setting natural flower beds.

The calligraphy effect must be paid attention to when matching the micro engraving inscriptions on the micro sculpture works. The creators should avoid the ugly appearance, the skew of characters, the uneven lines, the inaccuracy of paintings, and the imbalance of matching.
