This task requires great patience and concentration, since there is not the slightest room for error. The paper backing must be removed without damaging the original painting, otherwise its color, and the mood of the whole painting, might be changed.
這工作需很大的耐心，一小片、一小片的撕，一點也不能大意；且要盡可能不揭原托紙，僅揭覆背紙，否則色調會變，整幅古畫的氣氛也被破壞了。
