Cai Qi (; born December 5, 1955) is a Chinese politician, who is the current first-ranked secretary of the Secretariat of the Chinese Communist Party, fifth-ranking member of the CCP Politburo Standing Committee and close associate and confidante of General Secretary Xi Jinping. He is also the serving directors of both the CCP General Office and General Secretary's office, both powerful and influential positions within the internal administrative apparatus of the CCP. Cai began his career in Fujian province. He has served successively as the mayor of Sanming, the mayor of Quzhou, the mayor of Hangzhou and the Communist Party secretary of Taizhou, Zhejiang. Beginning in 2010 he served as the executive vice governor of Zhejiang Province, and in 2014 was transferred to Beijing to serve as deputy director of the CCP National Security Commission Office (rank equivalent of minister). Between 2017 and 2022, he was the Communist Party Secretary of Beijing. Largely due to Cai's extensive experience working in Zhejiang province, he is believed to be a political ally of CCP General Secretary Xi Jinping. Early life 
Cai was born in Youxi County, Fujian province on December 5, 1955. During the latter years of the Cultural Revolution he worked at the Xiyang Commune, Yong’an County, Fujian. He joined the Chinese Communist Party (CCP) in 1975. Cai attended Fujian Normal University and graduated in 1978 with a degree in political economics. Afterwards, he stayed in the university as an official in its CCP committee, working there until 1983. Early local careers

Fujian
In 1983, he was transferred to the Fujian Provincial CCP Committee, working there as a clerk until 1985, then working as a division deputy head between 1985 and 1987, and then working as a mishu at a General Work Department between 1987 and 1991. He worked as the deputy director of the Office of Political Reform between 1991 and 1992, deputy director of the Party Building Department between 1992 and 1993, and deputy director of the Provincial Party General Office between 1993 and 1996. As deputy director of the General Office, he was primarily a personal secretary to then Fujian CCP secretary Chen Guangyi. Between 1994 and 1997, he pursued a post-graduate degree in economic law at his alma mater via part-time studies. He additionally attended a four-month training program for department and prefecture-level cadres at the CCP Central Party School in 1996. In September 1996 Cai took on his first major role in local government as the deputy CCP secretary and later mayor of the city of Sanming in Fujian, working there until 1999. Zhejiang
He was transferred to Zhejiang province in May 1999 serving as the deputy CCP Secretary and Mayor of Quzhou, working there until 2002. Cai additionally pursued a doctoral degree in political economics, which he obtained from September 1999 to July 2001 at Fujian Normal University through part-time studies. Between March 2002 and April 2004 Cai served as Quzhou's CCP secretary, the top political office of the city. In April 2004 Cai became party secretary of Taizhou, Zhejiang; at the time, Xi Jinping was the party secretary of Zhejiang province. In April 2007, Cai was promoted to the position Mayor of Hangzhou, the provincial capital, also serving as deputy CCP Secretary. In January 2010, he became a member of the provincial CCP Standing Committee as head of the party's provincial Organization Department. In November 2013, Cai became the Executive Vice Governor of Zhejiang province. He made the announcement of his change in jobs on his microblog account. Beijing 

In March 2014, Cai was said to have been transferred to Beijing to work as the deputy director of the General Office of the CCP National Security Commission, a newly established body led by CCP general secretary Xi Jinping, though no official announcement was made about this appointment. Given his Zhejiang work experience and his current position and seniority, Cai has been named as a member of the so-called "New Zhijiang Army", i.e., officials who at one point worked under Xi Jinping during his term as Zhejiang party secretary. After his transfer to Beijing, Cai stopped updating his various social media accounts. The only indication of his whereabouts appeared in news footage at numerous "study sessions" of the CCP Politburo, where he was shown seated next to other minister-level officials, suggesting that he was an official of full provincial-ministerial rank and working for the central party organization. It was later confirmed that he was serving as deputy director of the Office of the National Security Commission. Party Secretary of Beijing 
On 31 October 2016, Cai was appointed acting mayor of Beijing, replacing Wang Anshun, later being formally appointed as mayor by the Beijing Municipal People's Congress on 20 January 2017. He was also appointed as the deputy CCP committee secretary of Beijing. In May 2017, Cai was appointed as CCP committee secretary of Beijing. Cai's appointment broke nearly all conventions in post-Cultural Revolution political tradition; he was neither a member nor alternate member of the Central Committee, and took on an office that would, under normal circumstances, be accorded Politburo membership. He was appointed to the 19th CCP Politburo immediately after the 19th CCP National Congress in October 2017, becoming one of the few people to be appointed to the Politburo before serving at the CCP Central Committee. In 2017, early in his tenure, Cai came under controversy due to the forceful eviction of many migrant workers from Beijing. At a leaked video of a speech he made a day after fires in southern Beijing on 18 November, Cai said "some should have been cleared long ago, but that’s difficult, so no one dared to do it", referring to unapproved dwellings. Afterwards, he publicly took a more conciliatory tone warning against “oversimplified” and “hasty” evictions. During his tenure, Cai Qi promoted green development, particularly environmental protection, in Beijing. He also devoted work to national security issues, especially cybersecurity. In June 2020, Cai was appointed to lead the team charged with the elimination of coronavirus in the Xinfadi market. As the Beijing Party secretary, Cai was responsible for organizing the  2022 Olympic and Paralympic Winter Games in Beijing. In June 2017, he was appointed President of the Beijing Organising Committee for the 2022 Olympic and Paralympic Winter Games. He gave an opening speech during the opening ceremony of the Olympics, as well as during the closing ceremony. He was awarded the Gold Olympic Order after the Olympics. Top leadership 
Following the 1st Plenary Session of the 20th CCP Central Committee, held after the closing day of the 20th Party Congress in October 2022, Cai was appointed to the CCP Politburo Standing Committee as its fifth-ranking member, also becoming the first-ranking secretary of the CCP Secretariat. In March 2023, he became the director of the CCP General Office, succeeding Ding Xuexiang; this made him the first General Office director that's also member of the Politburo Standing Committee since Wang Dongxing. Cai was revealed as a deputy head of the CCP National Security Commission in May, the first time one of the deputy heads was someone other than the premier or the chairman of the Standing Committee of the National People's Congress. Cai has also frequently accompanied Xi on trips, responsible for arranging his security, schedule and daily affairs. Public image
Cai is known for his extensive use of social media and his unorthodox approach to governance. Cai has referred to Xi as "Xi Dada" (Father Xi) and "Boss Xi!" in public media. The Economist opined in 2017 as Cai "rocketed up the Communist Party’s ranks" that "Xi Jinping has chosen an unusual man to lead the capital city." Cai is said to have been a fan of Kevin Spacey's House of Cards TV serial, and was cited as a fan of the iPhone product. Cai maintains a Weibo microblog account under the subtitle "Cai Qi, a Bolshevik", which has been active since May 2010. The account was initially opened under the name Qianshui (潜水; literally, "scuba diving"), but he was eventually 'outed' by internet users. The account is 'followed' by over ten million people. He used it regularly to communicate with citizens. As a sub-provincial-level official Cai was one of the highest-ranking officials to maintain a regular social media presence. It is the opinion of certain political scholars that Cai used this Weibo tool to circumvent existing CCP apparatus and thereby gain public profile, "considerable influence" within the CCP and thereby promotion. Cai has stated of the CCP that:

On the evening of 14 September 2013, a mother of an ordinary government staffer working for the national revenue agency posted on her microblog feed that her son was expected to partake in heavy drinking with superiors on a regular basis as part of his work and that it was affecting his health. The mother pleaded for attention to the case by then Zhejiang party organization chief Cai Qi. A day later Cai responded to her asking which department her son worked at and vowed publicly "your son doesn't have to drink from now on." During his four years of using Weibo, he averaged more than six posts a day, which he compiled into a book called "A Room Made of Glass", saying he choose the title to promote transparency. He spoke about sensitive political topics in China, saying it was a "shame" the Facebook couldn't be accessed in China, and talking about the conviction of Ingo Heinrich, an East German body guard who was convicted after shooting Chris Gueffroy for trying to escape the Berlin Wall. He also broke conventions, announcing his promotion as the deputy director of the Office of the National Security Commission through Weibo, before the Chinese state media reported on it. He stopped posting on Weibo after his transfer to Beijing. Personal life 
Before retirement, Cai Qi's wife was a bureau-level official in Zhejiang. The couple have a son, who previously worked as an official at the subdistrict level in Hangzhou and as a staff member at the National Development and Reform Commission. References
