Ershisi huapin 二十四畫品 is an essay on the classification of paintings written during the mid-Qing period 清 (1644-1911) by Huang Yue 黃鉞 (1750-1841), courtesy name Zuotian 左田 or Zuojun 左軍, style Zuojun 左君, posthumous title Qinmin 勤敏, from Dangtu 當塗, Anhui. He obtained his jinshi degree in 1790 and was Minister of Revenue (hubu shangshu 户部尚書). Huang was an excellent calligrapher and painter, with a focus on landscape painting. His most important writings are the poetry collection Zuotian shichao 左田詩鈔 and Zuotian huayou lu 左田畫友錄, a book on painting.
The book, written around 1800, was inspired by Sikong Tu's 司空圖 (837-908) Ershisi shipin 二十四詩品, a classification of poetry. Huang's aspects of classification were resonance (qiyun 氣韻), inspiration and excellence (shenmiao 神妙), elegance in simplicity (gaogu 高古), freshness (cangrun 蒼潤), profundity and grandeur (chenxiong 沉雄), balance in frugality (chonghe 沖和), floating elementariness (danyi 淡逸), simple sincerity (puzhuo 樸拙), originality (chaotuo 超脫), extraordinariness (qipi 奇僻), unrestrainedness (zongheng 縱橫), uninhibitedness (linli 淋漓), desolateness and coldness (huanghan 荒寒), peacefulness (qingkuang 清曠), personality (xingling 性靈), perfectness (yuanhun 圓渾), depth and quietness (yousui 幽邃), brightness and clarity (mingjing 明凈), robustness and vigour (jianba 健拔), clear succinctness (jianije 簡潔), diligent focusing (jingqin 精勤), lively gracefulness (junshuang 雋爽)，startling flexibility (konglin 空靈), and delicate beauty (shaoxiu 韶秀).
