New Confucianism: New Confucianism () is an intellectual movement of Confucianism that began in the early 20th century in Republican China, and further developed in post-Mao era contemporary China.  It is deeply influenced by, but not identical with, the Neo-Confucianism of the Song and Ming dynasties.  It is a neo-conservative movement of various Chinese traditions and has been regarded as containing religious overtones; it advocates for certain Confucianist elements of society - such social, ecological, and political harmony - to be applied in a contemporary context in synthesis with Western philosophies such as rationalism and humanism.

New Text Confucianism: New Text Confucianism () is a school of thought in Confucianism that was based on Confucian classics recompiled in the early Han dynasty by Confucians who survived the burning of books and burying of scholars during the Qin dynasty.  The survivors wrote the classics in the contemporary characters of their time, and these texts were later dubbed as "New Text".  New Text school attained prominence in the Western Han dynasty and became the official interpretation for Confucianism, which was adopted as the official ideology by Emperor Wu of Han.  Represented by Confucians such as Dong Zhongshu, this school advocated a holistic interpretation of Confucian classics and viewed Confucius as a charismatic, visionary prophet, a sage who deserved the Mandate of Heaven but did not attain kingship due to circumstances.  The school competed with Old Text Confucianism in the later Han dynasty and its dominance waned as the latter became the new orthodoxy.  The school fell into obscurity during the chaotic period after the fall of the Han dynasty and remained so until late Ming dynasty in the 17th century.

Jangnye: Jangnye refers to Korean funerary rites.  "Jangnye" has been practiced since the book "The Family Rituals of Zhu Xi" (朱子家禮, "Zhuzi jiali") was introduced from China during the Joseon Dynasty.  Rulers during the era wanted to erase the Buddhist ceremonies of the previous dynasty, Goryeo, and to replace them with the ceremonies of Confucianism.

Gongyang Zhuan: The Gōngyáng Zhuàn (, ) is a commentary on "Chunqiu", or the "Spring and Autumn Annals", and is thus one of the classic books of ancient Chinese.  Along with the "Zuo Zhuan" and the "Guliang Zhuan", the work is one of the "Three Commentaries on the Spring and Autumn Annals".  In particular, "Gongyang Zhuan" is a central work to New Text Confucianism (今文經學), which advocates Confucius as an institutional reformer instead of a respected scholar, and "Chunqiu" as an embodiment of Confucius' holistic vision on political, social, and moral issues instead of a merely chronicle.  "Gongyang Zhuan" significantly influenced the political institution in Han Dynasty.  It fell out of favor among elites and was eventually replaced by the "Zuo Zhuan".  "Gongyang Zhuan" scholarship was reinvigorated in late Ming Dynasty and became a major source of inspiration for Chinese reformers from eighteen to early twentieth century.

Rulers from five ethnic groups, the Xiongnu, Xianbei, Jie, Qiang and Di, then established a series of independent kingdoms in what is now northern China.
