The continent is bounded by 32 degrees north latitude and low west and east and low according to the terrain, which divides the two areas of different geological and meteorological conditions in the north and south.
In the five northwestern provinces, the soil is mostly alkaline, while the eastern elevation is low, the soil is moist and fertile and acidic, and the soil, meteorological and hydrological conditions of these regions are different, coupled with the different preservation materials and locations of each pit, resulting in different manifestations of jade alteration and weathering.
I believe that regional characteristics and pit characteristics are two concepts and cannot be confused.
The area is the space where the ancient jade is located, and the pit mouth is just a point in this space.
The change of the artifacts in this point will produce different degrees of alteration and weathering of the material due to the difference in placement and age, but their alteration and weathering commonality must have regional characteristics.
For example, the north is multi-earth Qin (yellow Qin), and the southern multi-water Qin (white Qin) is a good proof.
At present, the books and related materials on ancient jade are basically elaborated from the perspective of historical and cultural order.
This is beneficial for ancient jade lovers to understand the inheritance and continuation and connection of jade culture, but from the perspective of research and appreciation of ancient jade, the author feels that at least it is lacking.
The different regional characteristics of ancient jade in different regions have their commonalities.
Whether it is handed down or unearthed jade, after a long period of erosion of water and soil and other materials, it will inevitably leave a variety of different imprints, thus providing the most reliable basis for identifying ancient jade.
From a cultural point of view, we can divide the generations and periods from the shape and ornamentation, but as a major feature of appreciating ancient jade, Qin color.
The first thing to consider is the correspondence between the different elements and colors contained in different regions, plus jade.
Without understanding these relationships, it is difficult to accurately judge this main feature.
After figuring out the relationship between alteration and weathering and regional soil, meteorology, hydrology, and jade materials, it is necessary to consider the location of the pit mouth tomb, the preservation conditions and whether it has been destroyed.

Finally, the placement of ancient jade in the pit mouth and the possible environmental conditions of the placement position should be considered.
For example: inside and outside the coffin, inside the container, attachments, etc.
The process of judging, appreciating, and judging the alteration and weathering of ancient jade is what I call the "trilogy.".
Many friends may feel that this formulation is a bit off the line.
Don't worry, take your time;
The first step is to look at the collection of the museum, to understand the commonality of the characteristics of ancient jade in museums in different regions;
The second step is to analyze according to the intuitive performance of the artifact (e.g., qin color, smeared cinnabar, mutilated performance,);
The third part can be analyzed and compared according to the excavation report of similar artifacts to obtain general information.
We have to take the questions to visit and admire the observation artifacts. If there is no destination to see, it is equivalent to walking and looking at flowers, there will be no harvest and knowledge income.
To try to verify the connoisseurship and information learned from books, materials, teachers, and friends, it is often misguided to copy them in general.
Open up ideas, absorb the essence, learn from each other, do not understand not to move, would rather miss, never impulsive.
