Cultural Revolution: The Cultural Revolution, formally the Great Proletarian Cultural Revolution, was a sociopolitical movement that took place in China from 1966 until 1976.  Set into motion by Mao Zedong, then Chairman of the Communist Party of China, its stated goal was to preserve 'true' Communist ideology in the country by purging remnants of capitalist and traditional elements from Chinese society, and to re-impose Maoist thought as the dominant ideology within the Party.  The Revolution marked the return of Mao Zedong to a position of power after the Great Leap Forward.  The movement paralyzed China politically and negatively affected the country's economy and society to a significant degree.

Cultural Revolution Group: The (Central) Cultural Revolution Group (CRG or CCRG; ) was formed in May 1966 as a replacement organisation to the Central Committee Secretariat and the "Five Man Group", and was initially directly responsible to the Standing Committee of the Politburo.  It consisted mainly of radical supporters of Mao, including Chen Boda, the Chairman's wife Jiang Qing, Kang Sheng, Yao Wenyuan, Zhang Chunqiao, Wang Li and Xie Fuzhi.  The CRG played a central role in the Cultural Revolution's first few years, and for a period of time the group replaced the Politburo Standing Committee (PSC) as the "de facto" top power organ of China.  Its members were also involved in many of the major events of the Cultural Revolution.

Iranian Cultural Revolution: The Cultural Revolution (1980–1983) (Persian: انقلاب فرهنگی‎ ‎ ) was a period following the Iranian Revolution, when the academia of Iran was purged of Western and non-Islamic influences (even traditionalist unpolitical Islamic doctrines) to bring it in line with the revolutionary and Political Islam.

Central Case Examination Group: The Central Case Examination Group (; CCEG) was a special organization established in the People's Republic of China in 1966 under the aegis of the Politburo Standing Committee to persecute those accused of "anti-party activities".  It was, in essence, an organization dedicated to political persecution of senior party leaders as well as ordinary functionaries.  Initially conceptualized as a beachhead by Chairman Mao Zedong's most radical supporters to 'gather dirt' on opponents of the Cultural Revolution, it later began taking up cases against all manner of perceived political opponents irrespective of their ideological allegiance.  Ironically, many of its early leaders, such as Jiang Qing, later themselves became the subject of persecution by the Group.  The Group was compared by Cultural Revolution-era propagandist Wang Li to the Soviet Cheka, but he noted that the CCEG had even broader powers.  Its leading members included nearly all of the members of the Cultural Revolution Group (CRG) as well as Premier Zhou Enlai and the chief of Mao's security detail Wang Dongxing.  The CCEG worked closely with the CRG during its investigations.

Chairman Mao badge: Chairman Mao badge () is the name given to a type of pin badge displaying an image of Mao Zedong that was ubiquitous in the People's Republic of China during the early period of the Cultural Revolution, from 1966 to 1971.  The term is also used for badges associated with Mao that do not actually have a picture of him on them.  Chairman Mao badges were, together with the "little red book", one of the most visible and iconic manifestations of the Cult of Mao.  It is estimated that several billion Chairman Mao badges were produced during the period of the Cultural Revolution.

Cultural Revolution (Libya): The Cultural Revolution (or People's Revolution) in Libya was a period of political and social change in Libya.  It started with Gaddafi's declaration of a cultural revolution during a speech in Zuwara on 15 April 1973.  This came after increasing tensions between Gaddafi and his colleagues in the Revolutionary Command Council (RCC) had led him to agree to step down.  Gaddafi had told the RCC that he would announce his resignation to the people at the Zuwara speech, but he instead surprised them with his declaration of the Cultural Revolution.  By the end of the Cultural Revolution period, Gaddafi was the uncontested leader of Libya.

Hong was the longest serving disciple for the Chen-style t'ai chi ch'uan (陈式太极拳) master Chen Fake (陈发科, 1887–1957).  Starting in 1930, Hong trained uninterrupted with Chen for fifteen years.  In 1956, Hong moved to Jinan (济南), Shandong Province (山东省).  There, he practiced and researched the meaning of Chen-style t'ai chi ch'uan.  He expressed his own understanding of the "ch'uan" through his teachings and his writings.  His theories and training principles are now known as the Practical Method for Chen-style t'ai chi ch'uan (陈式太极实用拳法).  Through the turmoil of the Cultural Revolution, Hong maintained his dedication to the enrichment of his art.  In the Era of Restructuring, Hong had trained a new generation of Chen Stylists and wrote several articles to illuminate the mysteries of Chen-style t'ai chi ch'uan.  As China opened up to the international community, Hong was rediscovered as an important linkage to this ancient Chinese martial arts tradition.  T'ai chi enthusiasts from all over the world would come to train with this remarkable man.  Fame and fortune did not change Hong.  He remains steadfast to the ideals of the Tao.  Near the end of his life, old and in ill health, he would still maintain his daily t'ai chi training schedule and looked forward to doing Push hands with his students.  In 1996, aged 90 (according to the Chinese calendar), Hong died.  Hong is survived by his family, his dedicated disciples and the lasting legacy of his Practical Method.
