Huang Tingjian (1045–1105) was a Chinese calligrapher, painter, and poet of the Song dynasty. He is predominantly known as a calligrapher and is also admired for his painting and poetry. He was one of the Four Masters of the Song Dynasty and was a younger friend of Su Shi and influenced by his and his friends' practice of literati painting, calligraphy, and poetry. Huang Tingjian is noted for his prodigious talent in terms of his vast knowledge of Classical Chinese poetry and literature. Huang is also regarded as a particularly fine and creative calligrapher of the Song Dynasty. His xingshu (semi-cursive style of script) displays a sharpness and aggression that is instantly recognizable to students of Chinese calligraphy. His calligraphic piece Biographies of Lian Po and Lin Xiangru epitomises a technique today known as "flying-white" "when writing calligraphy, the areas within a brushstroke where the brush fails to leave a full measure of ink and streaks of white paper or silk appear". Huang Tingjian is considered to be the founder of the Jiangxi school of poetry.
