Abstract:A landscape painting by Tang Yin is a silk scroll painting in Shanghai Museum collection. Time-honored as it is, the painting appears to be aged, damaged, incomplete and badly creased, and is in urgent need of restoration. A restoration plan was made strictly in accordance with the five procedures of ancient painting and calligraphy restoration, namely, “washing, uncovering, repairing, supporting and inpainting”. The restoration process also firmly adhered to the principles of “minimum intervention” “maximum information retention” and “safety”. Based on comparison of pictures before and after restoration, the restoration plan was found successful. Through constant practice, theoretical research and further discussion, the most suitable restoration method can be adopted for each cultural relic.
