Tang Yin's book "Shuangjian Xingwo Ji", paper, attached to Tang's "Shuangjian Xingwo Tu", this picture and the illustration are made by Wang Rong, a literati in Fuxi, Xin'an, Anhui Province. Tang Yin illustrated the different functions of gold, water, and heart as a mirror in the illustrations, and described Wang's "building a room with a number of trees", "reading among them", "mezzanine room chiseling pond two areas" as "double jian", and "if it is for life, then the lintel of the room is called the double jian". It means taking water as a mirror and taking the house as a nest. There is an allusion here, that is, the "History of the Song Dynasty - The Biography of Shao Yong" records that Shao Yong lived in seclusion, and his name was called "Comfort Nest". "Those who do good deeds do not make houses, such as Yong's dwelling, in order to wait for their deeds, and the name is "Xingwo". The drawings related to this allusion also include the volume of Ni Zhan's "Lazy Nest" in the Yuan Dynasty and the volume of "Yunshui Xingwotu" by Shen Zhouzhi in the Ming Dynasty.
Tang Bohu studied Zhao Meng, elegant and graceful, charming and beautiful. And Tang Bohu wrote this "Shuangjian Xingwo Ji" when he was 50 years old, which shows the artistic aesthetics of ancient and clumsy. At this stage, calligraphers are already old, and they no longer deliberately express their proficiency in technique, but are natural, do not choose pen and paper, and become high-level by themselves.
Fifty-year-old Tang Bohu can be said to have reached the realm of extreme work. But this work is placed in the middle of all Tang Bohu's calligraphy works, but it seems to be relatively "raw", or it may be because of the baldness of the pen, it is difficult to show his usual beauty, and the beauty of the gossamer reflected by the tip of the pen. But it is also unique, showing the beauty of the ancient and vigorous.
