IN: Xi Jinping (; Chinese: Xi Jin Ping ; pinyin: Xi Jinping; born 15 June 1953) is a Chinese politician currently serving as General Secretary of the Communist Party of China, President of the People's Republic of China, and Chairman of the Central Military Commission. As Xi holds the top offices of the party, the state, and the military, he is sometimes referred to as China's "paramount leader"; in 2016, the party officially gave him the title of "core" leader.

Xi was appointed to the nine-man Politburo Standing Committee of the Communist Party of China at the 17th Party Congress in October 2007. Xi was ranked above Li Keqiang, an indication that he was going to succeed Hu Jintao as China's next leader. In addition, Xi also held the top-ranking membership of the Communist Party's Central Secretariat. This assessment was further supported at the 11th National People's Congress in March 2008, when Xi was elected as Vice-President of the People's Republic of China. Following his elevation, Xi has held a broad range of portfolios. He was put in charge of the comprehensive preparations for the 2008 Summer Olympics in Beijing, as well as being the central government's leading figure in Hong Kong and Macau affairs. In addition, he also became the new President of the Central Party School of the Communist Party of China, the cadre-training and ideological education wing of the Communist Party. In the wake of the 2008 Sichuan earthquake, Xi visited disaster areas in Shaanxi and Gansu. Xi made his first foreign trip as vice president to North Korea, Mongolia, Saudi Arabia, Qatar and Yemen from 17 to 25 June 2008. After the Olympics, Xi was assigned the post of Committee Chair for the preparations of the 60th Anniversary Celebrations of the founding of the People's Republic of China. He was also reportedly at the helm of a top-level Communist Party committee dubbed the 6521 Project, which was charged with ensuring social stability during a series of politically sensitive anniversaries in 2009. Xi is considered to be one of the most successful members of the Crown Prince Party, a quasi-clique of politicians who are descendants of early Chinese Communist revolutionaries. Former Prime Minister of Singapore, Lee Kuan Yew, when asked about Xi, said he felt he was "a thoughtful man who has gone through many trials and tribulations." Lee also commented: "I would put him in the Nelson Mandela class of persons. A person with enormous emotional stability who does not allow his personal misfortunes or sufferings affect his judgment. In other words, he is impressive". Former U.S. Treasury Secretary Henry Paulson described Xi as "the kind of guy who knows how to get things over the goal line." Australian Prime Minister Kevin Rudd said that Xi "has sufficient reformist, party and military background to be very much his own man." Former US Secretary of State Hillary Clinton tweeted, "Xi hosting a meeting on women's rights at the UN while persecuting feminists? Shameless."

Background: James Watt (30 January 1736 (19 January 1736 OS) - 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1781, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.
Context: Watt retired in 1800, the same year that his fundamental patent and partnership with Boulton expired. The famous partnership was transferred to the men's sons, Matthew Robinson Boulton and James Watt Jr. . Longtime firm engineer William Murdoch was soon made a partner and the firm prospered. Watt continued to invent other things before and during his semi-retirement. Within his home in Handsworth, Staffordshire, Watt made use of a garret room as a workshop, and it was here that he worked on many of his inventions. Among other things, he invented and constructed several machines for copying sculptures and medallions which worked very well, but which he never patented. One of the first sculptures he produced with the machine was a small head of his old professor friend Adam Smith. He maintained his interest in civil engineering and was a consultant on several significant projects. He proposed, for example, a method for constructing a flexible pipe to be used for pumping water under the Clyde at Glasgow. He and his second wife travelled to France and Germany, and he purchased an estate in mid-Wales at Doldowlod House, one mile south of Llanwrthwl, which he much improved. In 1816 he took a trip on the paddle-steamer Comet, a product of his inventions, to revisit his home town of Greenock. He died on 25 August 1819 at his home "Heathfield" in Handsworth, Staffordshire (now part of Birmingham) at the age of 83. He was buried on 2 September in the graveyard of St Mary's Church, Handsworth. The church has since been extended and his grave is now inside the church.
Question: what happened in his later years?
Answer:
Watt retired in 1800, the same year that his fundamental patent and partnership with Boulton expired.
