古書畫，如作者名氣相近，則畫價優于書價，傳世少者優于傳世多者。畫中以山水為上，次為人物，再次為花鳥竹石、走獸蟲魚。字中以楷為上，次書行書，再次為草書。從書畫的保存來看，以紙絹完整不破、幅面清潔無垢、背面沒有補貼者為上品。
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、紙絹鑒別：因為各個時代的紙絹質料都有不同，如宋代絹橫、豎都用單絲，而橫線比豎線稍寬；元代絹經緯仍為單絲，但絲細，紋理較?。幻鞔佖Q仍為單線，橫則為雙線；清代絹橫豎都為雙線。紙質也依朝代而變。所題的書畫的朝代應與紙絹質地相對應。
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、墨色鑒別：隨著年代的久遠，筆墨的顏色會出現差別。如宋以前的書跡，常有不明顯的白霜，無刮痕，輕摸不退。仿造品，則多用香灰吹散在偽品表面，輕擦即去，露出黑亮的新跡。
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、裝裱形式：元以前，書畫裱成立軸的格式少見；明代時立軸增多，多寬邊，麥黃色寬綾圍圈，上下用深藍花綾；清代立軸用兩色絹或綾作圍圈。
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、印記：印章也隨朝代而用不同的材料，從這些方面也可以推斷。
4 mark: the seal is also used in different materials in the dynasty, and can be inferred from these aspects.
