畫面上的白點為干霉，可以先用雞毛撣子輕輕掃除，再用熱水沖洗兩遍，白霉就可以去除。

　　The white spots on the screen are dry mold. You can first gently sweep them with a chicken feather duster, and then rinse them twice with hot water to remove the white mold.

　　如果白霉繼續(xù)受潮而不處理，就會轉(zhuǎn)化成綠色霉斑和黃色霉斑。 再發(fā)展下去就變成了紅霉，這時候就要再太陽下曬一下，等待紙張完全干透，用干燥的小毛筆將霉點表面去除。 然后用熱水沖洗一次，在霉點上先涂抹淡高錳酸鉀溶液，等待顏色變成了紫色后，涂抹淡草酸水，一般情況下，霉斑即可去除。

　　If white mold continues to be damp without treatment, it will transform into green and yellow mold spots. If it continues to develop, it will become red mold. At this point, it needs to be sun dried again, wait for the paper to completely dry, and use a dry small brush to remove the surface of the mold. Then rinse with hot water once, apply a light potassium permanganate solution to the mold spots, wait for the color to turn purple, and then apply light oxalic acid water. Generally, the mold spots can be removed.

　　紅霉難處理可以用淡淡的漂白粉局部進行處理，然后用清水沖洗即可。 黑霉是字畫無法處理的霉，通常這種情況下的紙張纖維完全被破壞，所以直接使用淡漂白液即可，只是很難，甚紙張消失，需要挖掉再補。 以上辦法都是使用酸性化學(xué)物質(zhì)腐蝕霉斑，達到去除霉斑的方法，對字畫紙張纖維有傷害。

　　The most difficult to treat red mold can be treated locally with light bleach, and then rinsed with clean water. Black mold is the most difficult mold to handle in calligraphy and painting. In this case, the paper fibers are completely destroyed, so using light bleach directly is sufficient. However, it is difficult to remove, and even the paper disappears. It needs to be dug out and repaired. The above methods all use acidic chemicals to corrode mold spots, achieving the method of removing mold spots and causing damage to the fibers of calligraphy and painting paper.
