《雪夜访普图》轴，明，刘俊作，绢本，淡设色，纵143.2cm，横75cm。

　　此图描写宋太祖赵匡胤雪夜访赵普的历史故事。据《宋史·赵普本传》记载：“太祖数微行过功臣家，普每退朝，不敢便衣冠。一日，大雪问夜，普意帝不出。久之，闻叩门声，普亟出，帝立风雪中，普惶惧迎拜，帝曰：‘已约晋王矣。'已而太宗至，设重裀地坐堂中，炽炭烧肉，普妻行酒，帝以嫂呼之。因与普计下太原。”画面描绘的正是这一历史情景。在门庭宽敞、屋宇数重的枢密副史府内，前厅正中二人围炉而坐。上首坐的是宋太祖赵匡胤，他头扎巾帽，身穿盘领窄袖袍服，腰束锦带，身材魁伟，气度不凡，其庄严的表情，侧首聆听的姿态，恰当地表现了深夜访贤、商议国家大事的仪态和心境。身着便服的枢密副史赵普在下首侧坐，恭谦地侃侃而谈，细致地刻画出了他诚恳献策的谋臣风度。画家在着意刻画主体人物的同时，对景象做了细致的描写。近岩远山，老树昏鸦，均被夜色笼罩着，竹叶、树枝、屋脊上覆盖着皑皑白雪，天气显然很寒冷。为突出赵匡胤的天子身份，在大门外象征性地画有四个侍卫，他们似乎守候已久。这些细微的描绘，深化了雪夜访贤的主题。

　　此画构图主次分明，主题突出，人物刻画精细生动，屋宇、什物结构精确，线条工整。山石树木的勾斫皴擦，既保持了宋人画的劲健之笔，又呈疏简之势，反映了明代院体画所呈现的变化。

This picture depicts the historical story of Zhao Kuangxu's visit to Zhao Pu on a snowy night by Song Taizu. According to the biography of Zhao Pu in the Song Dynasty, "Taizu has done a lot of meritorious deeds in his family, and he dares not wear plain clothes when he retires from the dynasty." One day, when the snow asked the night, Emperor Puyi did not go out. Over time, when he heard the knock on the door, he rushed out and worshipped the emperor fearfully in the snowstorm. The emperor said,'The King of Jin has been appointed. Taizong arrived, set up a heavy seat in the hall, burning charcoal, burning meat, ordinary wives to drink, the emperor called it. Because of the general plan of Taiyuan. It is this historical scene that the picture depicts. In the Privy Deputy historic hall with spacious doorways and multiple houses, two people sit in the middle of the lobby surrounded by a fireplace. First sitting was Zhao Kuangxu, Taizu of the Song Dynasty. He wore a scarf and cap, a narrow sleeve gown with a bow collar and a brocade belt. He was very tall and magnificent. His solemn expression and listening attitude appropriately reflected the attitude and mood of visiting the virtuous people late at night and discussing state affairs. Mr. Shi Zhaopu, the deputy secretary in civilian clothes, sat down at the bottom and talked humbly, depicting in detail the manner of his sincere advisers. Painters deliberately depict the main characters, at the same time, they make a detailed description of the scene. Near Yanyuan Mountain, old trees and crows are shrouded by night. Bamboo leaves, branches and roofs are covered with white snow. The weather is obviously very cold. In order to highlight Zhao Kuangxun's status as the emperor of heaven, four guards were symbolically painted outside the gate, which seemed to have been waiting for a long time. These subtle descriptions deepen the theme of visiting virtuous people on snowy nights.

The composition of the painting is clear, the theme is prominent, the characters are delicate and vivid, the structure of the house and objects is precise, and the lines are neat. The rubbing of rocks and trees not only maintained the vigorous and vigorous style of Song paintings, but also showed the tendency of simplicity, reflecting the changes of Ming Dynasty courtyard paintings.
