石渠寶笈初編(重華宮),下冊,頁712-714&*故宮書畫錄(卷三),第一冊,頁252-253&*故宮歷代法書全集,第十六冊,頁68-91、173-179&*Chang Yu, a native of Chekiang, was a famous Taoist of the Yuan. His writing is pure, while his painting and calligraphy are untrammeled. Ni Tsan praised his art as "the best among Taoist works." In the whole work, the beginning and end of the strokes are clearly distinguished, but the manner is flowing and pure while the structure is solid. Where the running script is free and natural, we see traces of his early study of Chao Meng-fu's style. The arrangement is open, revealing an appearance of peace and lightness. The otherworldly style of Taoist calligraphers reaches beyond the mundane worled and makes the viewer feel as if in the realm of the immortals. This is the 7th leaf from Works by Yuan Calligraphers.&*張雨(西元一二八三-一三五0年),字伯雨,號句曲外史,浙江錢塘人。元代著名的道教人物。文才清麗,書畫清逸,倪瓚稱其詩文字畫為「道品第一」。 整幅書作,用筆頓挫分明,俊爽清遒。結體圓實,行筆瀟灑之處,可看出早年學趙孟頫的跡象。章法疏朗,呈現一派平和恬淡之象,道人書家超塵絕俗的「仙氣」若現其間。
