Matters needing attention in painting and calligraphy collection
After hanging the painting for a long time, the dust fell on the painting, and the painting was wiped with a wet cloth by mistake, so that the painting and calligraphy were wrinkled by water. If you want to remove dust, you should gently dust it with a feather duster. Never wipe with a (wet) cloth. Often hung in the wind, sun and rain, it will make the fibers of painting and calligraphy paper aging and fragile, yellow and discolored, mildew spots, water marks and so on. You should try to avoid being blown by wind and rain, and you also need to prevent direct sunlight from hitting your heart.
Painting and calligraphy hanging near the kitchen were damaged by oil pollution. It will make the paper glossy and dull, and the painting heart will easily absorb dust, thus losing its aesthetic feeling. Hanging pictures should avoid kitchens and places susceptible to oil pollution. Hanging paintings and calligraphy in damp or damp places will lead to mildew spots and serious mildew (such as newly renovated new houses, rainy and wet walls, especially ceramic tile walls). If the wall is dry, you can't hang pictures. It should hang in a dry place.
