《雨后帖》页，晋，传晋王羲之书，纸本，行草，纵25.7厘米，横14.9厘米。
释文：
今日雨后未果奉状，想□能于言话，可定便得书问，永以为训。妙绝无已，当其使转。与都下□信，戴适过于□也。羲之。
署款下一草押不识，又“禹民”二字题名。
鉴藏印有 “世南”、“贞观”（画描墨印），以及“四代相印”（朱文，伪）、“志东奇玩”（朱文，伪）、“绍兴”（朱文联珠），清乾隆、嘉庆、宣统内府诸印。
《雨后帖》传为王羲之所书的一通信札，所谈之事不可考，书字不够规范，个别字难于辨认。
此帖最早见于清代安岐《墨缘汇观》：“雨后帖，草书，纸本，唐模，有‘世南’墨印。”今专家鉴定认为此帖并非王羲之亲书原迹，依据有三：一是此帖上清代以前的钤印中除“绍兴”外皆不真。书法确有沉雄古雅之气，但与《姨母》、《丧乱》诸帖和《兰亭序》对比相去甚远。二是从用纸分析，纸为深褐色带有细横帘纹的竹纸。而竹纸在晋代是没有的，宋苏轼《东坡志林》卷九曾云：“今人以竹为纸，亦古所无有也。”三是晋代的书写工具是实心笔，行笔时笔毫开叉而经常出现贼毫，然《雨后帖》则用兼毫笔，笔画既软又肥，字距之间笔势连带而出现牵丝，无一笔贼毫出现，因此不应为晋时所书。
从此帖的墨色浓淡变化观察，与运笔的启收、顿挫转折的徐疾和用力相吻合，无勾摹痕迹，因此判断此帖应是古临本，书写年代在北宋至南宋绍兴以前。

--------Introduction in English--------
"Rain Poster" page, Jin, Jin Wang Xizhi's book, paper, grass, 25.7 cm vertical, 14.9 cm horizontal.
Annotations:
After today's rain, if you want to be able to speak, you will surely have to ask questions and learn from them forever. Wonderful, when it turns. Dai Shi is too. All in all.
Underneath the signature, he could not read the word "Yu Min" and had the title of "Yu Min".
There are "Shinan", "Zhenguan" (painting ink print), and "Four Generations Imprint" (Zhu Wen, pseudo), "Zhidong Qiju" (Zhu Wen, pseudo), "Shaoxing" (Zhu Wenlian Zhu), "Qianlong, Jiaqing, Xuantong Neifu Seals in the Qing Dynasty.
After the postscript, there are Yuan Deng Wenyuan, Ming Dong Qichang's inscriptions and postscripts, and Ming Zou Zhilin's inscriptions and postscripts.
"Rain Hou Tie" was handed down as a correspondence of Wang Xi's book. What he said was not verifiable. The characters were not standardized enough, and it was difficult to identify individual characters.
This post was first seen in Anqi's "Moyuan Huiguan" in the Qing Dynasty: "After the rain, the poster, cursive script, paper, Tang model, there are"Shinan"ink prints." Experts now believe that this post is not the original of Wang Xizhi's pro-script, based on three reasons: first, it was not true in the pre-Qing Dynasty stamp except for Shaoxing. Calligraphy is indeed magnificent and elegant, but it is far from the "Aunt", "Mourning" and "Lanting Preface". Second, from the paper analysis, the paper is dark brown with fine horizontal curtain pattern of bamboo paper. Bamboo paper did not exist in Jin Dynasty. Song Sushi's "Dongpo Zhilin" Volume 9 Zengyun said, "Nowadays people use bamboo as paper, which is nothing in ancient times." Thirdly, the writing tools of Jin Dynasty were solid pens, which often appeared thieves when the pen was slightly opened. However, Rain Hou Tie used both soft and fat strokes. The strokes between the spacing and the strokes were linked, and no thieves appeared. Therefore, it should not be written by Jin Dynasty.
From then on, the observation of the change of ink color is consistent with the Enlightenment of Yunbi, Xu Ji and his strength in the turning point of setbacks and setbacks. There is no trace of depiction. Therefore, it is judged that this post should be an ancient Linben, written from the Northern Song Dynasty to the Southern Song Dynasty before Shaoxing.
