Zhou Enlai in the context of "Four Modernizations"

The Line of Actual Control (LAC), in the context of the Sino-Indian border dispute, is a notional demarcation linethat separates Indian-controlled territory from Chinese-controlled territory on their mutual border. The concept was introduced by Chinese premier Zhou Enlai in a 1959 letter to Jawaharlal Nehru as the "line up to which each side exercises actual control", but rejected by Nehru as being incoherent. Subsequently, the term came to refer to the line formed after the 1962 Sino-Indian War.

The LAC is different from the borders claimed by each country in the Sino-Indian border dispute. The Indian claims include the entire Aksai Chin region and the Chinese claims include Arunachal Pradesh/Zangnan. These claims are not included in the concept of "actual control".

The Korean Armistice Agreement (Korean: 한국정전협정; Hanja: 韓國停戰協定) is an armistice that brought about a cessation of hostilities of the Korean War. It was signed by United States Army Lieutenant General William Harrison Jr. and General Mark W. Clark representing the United Nations Command (UNC), North Korea leader Kim Il Sung and General Nam Il representing the Korean People's Army (KPA), and Peng Dehuai representing the Chinese People's Volunteer Army (PVA). The armistice was signed on 27 July 1953, and was designed to "ensure a complete cessation of hostilities and of all acts of armed force in Korea until a final peaceful settlement is achieved."

During the 1954 Geneva Conference in Switzerland, Chinese Premier and foreign minister Zhou Enlai suggested that a peace treaty should be implemented on the Korean peninsula. However, the US secretary of state, John Foster Dulles, did not accommodate this attempt to achieve such a treaty. A final peace settlement has never been achieved. The signed armistice established the Korean Demilitarized Zone (DMZ), the de facto new border between the two nations, put into force a ceasefire, and finalized repatriation of prisoners of war. The DMZ runs close to the 38th parallel and has separated North and South Korea since the Korean Armistice Agreement was signed in 1953.

The Sino-Soviet border conflict, also known as the Sino-Soviet crisis, was a seven-month undeclared military conflict between the Soviet Union and China in 1969, following the Sino-Soviet split. The most serious border clash, which brought the world's two largest socialist states to the brink of war, occurred near Damansky (Zhenbao) Island on the Ussuri (Wusuli) River in Manchuria. Clashes also took place in Xinjiang.

In 1964, the Chinese revisited the matter of the Sino-Soviet border demarcated in the 19th century, originally imposed upon the Qing dynasty by the Russian Empire by way of unequal treaties. Negotiations broke down amid heightening tensions and both sides began dramatically increasing military presence along the border. Sino-Soviet relations worsened further following the Soviet invasion of Czechoslovakia in 1968. Border confrontations escalated in March 1969 when a group of People's Liberation Army troops engaged Soviet border guards on Zhenbao Island in Manchuria, resulting in considerable casualties on both sides. Further clashes occurred in August at Tielieketi in Xinjiang and raised the prospect of an all-out nuclear exchange. The crisis de-escalated after Soviet Premier Alexei Kosygin met with Chinese Premier Zhou Enlai in September, and a ceasefire was ordered with a return to the status quo ante bellum.

Shaoxing is a prefecture-level city on the southern shore of Hangzhou Bay in northeastern Zhejiang province, China. Located on the south bank of the Qiantang River estuary, it borders Ningbo to the east, Taizhou to the southeast, Jinhua to the southwest, and Hangzhou to the west. As of the 2020 census, its population was 5,270,977 inhabitants among which, 2,958,643 (Keqiao, Yuecheng and Shangyu urban districts) lived in the built-up (or metro) area of Hangzhou–Shaoxing, with a total of 13,035,326 inhabitants.

Notable residents of Shaoxing include Wang Xizhi, the parents of Zhou Enlai, Lu Xun, and Cai Yuanpei. It is also noted for Shaoxing wine, meigan cai, and stinky tofu, and was featured on A Bite of China. Its local variety of Chinese opera sung in the local dialect and known as Yue opera is second in popularity only to Peking opera. In 2010, Shaoxing celebrated the 2,500th anniversary of the founding of the city.

The Lin Biao incident (Chinese: 九一三事件; lit. 'September 13 Incident') was an aircraft accident at 2:30 a.m. on 13 September 1971 involving Lin Biao, the sole Vice Chairman of the Chinese Communist Party. Everyone on board a PLAAF Hawker Siddeley Trident, including Lin and several members of his family, died when the aircraft impacted Mongolian terrain.

As Vice Chairman, Lin Biao had been the official heir to Chairman Mao Zedong since 1966. From 1970, a rift developed between on one side Lin and his power base in the Army and Politburo, and on the other side, Mao, his allies Jiang Qing and Zhou Enlai, and their PLA factions. Issues included Lin's growing power in the PLA and his prominent role in Mao's cult of personality, which Mao had criticized as excessive. The crash was a key event at the midpoint of the ten-year Cultural Revolution, following which the Gang of Four gained prominence.

Family planning policies historically enacted by the People's Republic of China have included specific birth quotas (three-child policy, two-child policy, and the one-child policy) as well as harsh enforcement of such quotas. Together, these elements constitute the population planning program of China. China's program should not be confused with the family planning programs instituted in other countries, which were designed to encourage parents to have the number of children they desired—in China, the provision of contraception through family planning programs was subservient to a birth planning program under which the government designated how many births parents could have in order to control the size of its population.

In CCP Chairman Mao Zedong's time, the Chinese Communist Party (CCP) had an ambiguous and changing attitude toward family planning, especially during the Great Leap Forward. Family planning was first introduced in the 1950s as a "recommendation," yet had never been strictly implemented until 1970, when the Military Control Commission of China's Ministry of Health announced that contraceptives would be provided free of charge, and Chinese Premier Zhou Enlai enacted population growth targets for urban and rural areas, respectively. Malthusian concerns continued, with two-child restrictions starting in the early 1970s under the later-longer-fewer program.

The Monument to the People's Heroes (Chinese: 人民英雄纪念碑; pinyin: Rénmín Yīngxióng Jìniànbēi) is a ten-story obelisk that was erected as a national monument of China to the martyrs of revolutionary struggle during the 19th and 20th centuries. It is located in the southern part of Tiananmen Square in Beijing, in front of the Mausoleum of Mao Zedong. The obelisk monument was built in accordance with a resolution of the first plenary session of the Chinese People's Political Consultative Conference (CPPCC) adopted on November 30, 1949, with construction lasting from August 1952 to May 1958. The architect of the monument was Liang Sicheng, with some elements designed by his wife, Lin Huiyin. The civil engineer, Chen Zhide (陈志德) was also instrumental in realizing the final product.

The monument is 37.94 meters high, sitting south to north, from bottom to top for the pedestal, giant pedestal, the pedestal body, the top of the monument, the pedestal inlaid with eight large reliefs and two small reliefs, all to the theme of the major events of modern Chinese history. The center stone of the stele is taken from Laoshan Mountain, Qingdao, with "Eternal glory to the people's heroes" handwritten by Chairman of the Chinese Communist Party Mao Zedong on the front, and the inscription written by Mao and Premier Zhou Enlai on the back. Since its construction, the monument has been repaired many times, and in 1961, the Monument to the People's Heroes was listed as a Major cultural heritage sites under national-level protection.
