The term “Yingou (銀鉤)” originally referred to silver or silver hooks, which were later extended to include headdresses, decorations, fishhooks, crescent and other multi-layered meanings. Originally, the word “Yingou (銀鉤)” refers to a hook made of or had the colour of silver. As its meaning extends, Yingou is also used to refer to headwear, design pattern, fishhook or new moon. When introduced into calligraphy, the term comes to have the meaning of smooth, curved strokes in calligraphy works and letters, and especially it refers to the skilful handling of the brush in Caoshu (草書) and even specifically the strokes in Xiaokai(小楷). The artistic character of "Yingouchaiwei(銀鉤蠆尾)" should include two aspects: first, the strokes of the first finger are strong and smooth, and the strokes are long and short, with strong bones, rich bones and fleshy, flowing and resilient lines. The second-finger characters are very restrained, majestic and majestic, with a strong and elegant, flowing and clean, extremely grassy yet chic posture beauty. “Yingouchaiwei(銀鉤蠆尾)”, a calligraphy term in Zhangcao(章草) during Six Dynasties, shall be understood from two dimensions —the gesture of strokes and the gesture of characters. Compared to the aesthetic pursuit for descriptive, ambiguous images in Six Dynasties, manners of Caoshu(Shechaigu, Wulouhen, Zhuihuasha, Yinyinni, Feiniaorulin, Jingsherucao, Gupengzizhen, Jingshazuofei, etc.) in Tang Dynasty — the sharp changes in brushwork, the texture of strokes — resembles more closely to “Yingouchaiwei” and gives a more specific, vivid account of the writing process and the strokes. Such brushwork transforms and evolves with the maturing and enriching of the styles and forms of Caoshu.
