　　掛展一年以2次為宜，一次一到兩個月。其余時間應該收藏。藏置環境要嚴格要求。是防蟲、防潮、防火，其次是控制和調節存放環境的溫、濕度，切忌高溫、高濕、重壓。蠹魚(也稱衣魚、紙魚)是無翅昆蟲，一般蛀食書畫表面，特別危害糨糊粘貼處。煙草甲的幼蟲對書畫危害極大，喜歡在書畫中打洞，而自身藏于洞內。一般書畫防蟲多用驅避劑，常用的有衛生球、樟腦丸、對二氯化苯，這些物品都是白色固體，易于揮發，其中對二氯化苯殺蟲能力強。存放環境要求書畫箱柜的密封性要好，使保存環境相對穩定。

　　Hang a year to 2 times a year, one to two months. The rest of the time should be collected. Tibetan environment to strict requirements. The first is insect resistant, moisture-proof, fire, followed by the control of temperature and humidity regulation and storage environment, avoid high temperature and high humidity and pressure. Bookworm (also known as Lepisma, silverfish) is a wingless insects, generally boring painting surface, especially harm paste paste. A larva of tobacco are harmful to the holes in the love of painting and calligraphy, calligraphy and painting, and its encave.

　　木箱以樟木為佳，因樟木本身就可防蛀，且密封性好。無論用哪種箱柜，都要把字畫懸空放置，下面留出空間放置干燥劑、防蟲劑。這些試劑都應當用布或透氣性較好的紙包起來，不可直接接觸書畫。若要移動或運輸字畫，千萬不能直接移動或搬運箱柜，而應打開箱柜，取出藥品，并將字畫固定好，避免字畫在箱內相互碰撞。根據大量的實驗證明，字畫適宜的保存溫度為14℃18℃之間，合適的相對濕度為50%60%，這樣的條件，不利于微生物、霉菌的生長和繁殖?？刂茲穸?，主要用干燥劑變色硅膠或無水氯化鈣?？刂茰囟?，則可用空調調節室內溫度。

　　Wooden box with camphorwood better, camphor itself can moth, with good sealing performance.

Control humidity, mainly using desiccant color silica gel or anhydrous calcium chloride. Control temperature, air conditioning can be used to adjust the indoor temperature.
