Huang-Lao in the context of "Feng Youlan"

Fajia (Chinese: 法家; pinyin: fǎjiā), or the School of fa (incl. law, method), often translated Legalism, was a bibliographic school of primarily Warring States period classical Chinese philosophy, including more administrative works traditionally said to be rooted in Huang-Lao Daoism. Addressing practical governance challenges of the unstable feudal system, their ideas 'contributed greatly to the formation of the Chinese empire' and bureaucracy, advocating concepts including rule by law, sophisticated administrative technique, and ideas of state and sovereign power. They are often interpreted along realist lines. Though persisting, the Qin to Tang were more characterized by the 'centralizing tendencies' of their traditions.

The school incorporates the more legalistic ideas of Li Kui and Shang Yang, and more administrative Shen Buhai and Shen Dao, with Shen Buhai, Shen Dao, and Han Fei traditionally said by Sima Qian to be rooted in Huang-Lao (Daoism). Shen Dao may have been a significant early influence for Daoism and administration. These earlier currents were synthesized in the Han Feizi, including some of the earliest commentaries on the Daoist text Daodejing. The later Han dynasty considered Guan Zhong to be a forefather of the school, with the Guanzi added later. Later dynasties regarded Xun Kuang as a teacher of Han Fei and Qin Chancellor Li Si, as attested by Sima Qian, approvingly included during the 1970s along with figures like Zhang Binglin.

Shen Dao (c. 350 – c. 275 BC) was a mid Warring states period Chinese philosopher and writer. Noteworthy as a predecessor influencing both Han Fei and Daoism, his remaining fragments are the most substantial of any Jixia Academy scholar, and may have been well known. Later classified as Legalist with Han Fei, Sima Qian discusses him with Jixia academy scholars, taking him as rooted in Huang-Lao (Daoism).

Early remembered modernly for his influence on the Han Feizi with regards the concept of shi (勢; 'power', 'potential', circumstantial advantage or authority), most of his work would appear to have concerned the concept of fa (administrative methods and standards, including laws) commonly shared by others that the Han Confucian archivists classified as Legalist, and does share some early administrative ideas with them.

The Huangdi Sijing (simplified Chinese: 黄帝四经; traditional Chinese: 黃帝四經; pinyin: Huángdì sìjīng; lit. "Yellow Emperor's Four Classics") are ancient Chinese texts thought to be long-lost, manuscripts of which however are generally thought to have been discovered among the Mawangdui Silk Texts in 1973. Also known as the Huang-Lao boshu (simplified Chinese: 黄老帛书; traditional Chinese: 黃老帛書; pinyin: Huáng-Lǎo bóshū; lit. 'Huang-Lao Silk Texts'), or Huangdi shu 黄帝書 (Yellow Thearch Manuscripts), they are thought by modern scholars to reflect a lost branch of early syncretist Daoism, referred to as the "Huang–Lao school of thought" named after the legendary Huangdi (黃帝; "Yellow Emperor") and Laozi (老子; "Master Lao"). One finds in it "technical jargon" derived of Taoism, Legalism, Confucianism and Mohism.

Empress Dou (Chinese: 竇皇后; died 29 June 135 BC), personal name Dou Yifang, posthumous name Empress Xiaowen (孝文皇后), was an empress consort of the Chinese Western Han dynasty who greatly influenced the reigns of her husband Emperor Wen and her son Emperor Jing with her adherence to Taoist philosophy; she was the main supporter of the Huang-Lao school. She therefore contributed greatly to the Rule of Wen and Jing, commonly considered one of the golden ages of Chinese history.
