古书画，如作者名气相近，则画价优于书价，传世少者优于传世多者。画中以山水为上，次为人物，再次为花鸟竹石、走兽虫鱼。字中以楷为上，次书行书，再次为草书。从书画的保存来看，以纸绢完整不破、幅面清洁无垢、背面没有补贴者为上品。
The ancient paintings, such as the famous painting is better than similar price price, less than those handed down handed down. The painting to landscape, for people, again for the bird and beasts bamboo fish. With Kai for word book, running script, cursive writing again. From the preservation of painting and calligraphy, the paper silk intact, clean, no scale, no subsidies for the back of the top grade.

１、纸绢鉴别：因为各个时代的纸绢质料都有不同，如宋代绢横、竖都用单丝，而横线比竖线稍宽；元代绢经纬仍为单丝，但丝细，纹理较稀；明代绢竖仍为单线，横则为双线；清代绢横竖都为双线。纸质也依朝代而变。所题的书画的朝代应与纸绢质地相对应。
1, the paper identified: because each era of paper and silk material are different, such as the Song Dynasty silk with horizontal and vertical and horizontal than vertical monofilament, slightly wider; the Yuan Dynasty silk Jingwei is still single, but fine silk texture, thin silk of Ming Dynasty; vertical is still single, double cross is the Qing Dynasty silk anyway; for the double. Paper also changes by dynasty. The paintings and paintings of the Dynasty should be corresponding to the texture of paper and silk.
２、墨色鉴别：随着年代的久远，笔墨的颜色会出现差别。如宋以前的书迹，常有不明显的白霜，无刮痕，轻摸不退。仿造品，则多用香灰吹散在伪品表面，轻擦即去，露出黑亮的新迹。
2, color identification: as time goes by, the ink color will appear. As before Song Dynasty calligraphy is not obvious, often glaucous, no scratches, light touch back. Imitation, then use ash blown in the pseudo surface, namely to graze, revealing new trace black.
３、装裱形式：元以前，书画裱成立轴的格式少见；明代时立轴增多，多宽边，麦黄色宽绫围圈，上下用深蓝花绫；清代立轴用两色绢或绫作围圈。
3, the form of mounting: before the yuan, and mounted into vertical format rare; the Ming Dynasty vertical increased, multi band, wheat yellow damask with wide circle, dark blue Ghatpot flower under the Qing Dynasty; with white silk or silk for vertical enclosure.
４、印记：印章也随朝代而用不同的材料，从这些方面也可以推断。
4 mark: the seal is also used in different materials in the dynasty, and can be inferred from these aspects.
