清代盛大士说过“画有四难”云云。本文借此“四难”作为视角，对苏轼《月梅》图进行鉴赏评析，并于欣赏之中揭示其创作特色：一是“外师造化，中得心源”，笔少面多，栩栩如生；二是以为正，奇、安相济，画势均衡，险不入怪；三是经营惨淡，布势天成，浑然画面节奏的律协和，生机勃勃；四是意境深邃，“物我相融”．这些意见时研究作为北宋“文人画”领袖的苏轼的绘画理论和绘画实践具有一定的启发意义． Sheng Shizong said in the Qing Dynasty “There are four difficulties” and so on. This dissertation takes “Four Hardships” as the angle of view to appraise Su Shi’s “Yuemei” figure and reveals its creative features in appreciation: First, ; Second is that is positive, odd, security and economy, draw a balanced, dangerous; third is the business bleak, natural, seamless rhythm of law and harmony; fourth is the artistic conception deep, melt“. It is of some enlightenment to study the painting theory and painting practice of Su Shi, the leader of the ”literati painting" in the Northern Song Dynasty.
