On this day, 125 years ago, August 30, 1900 (August 6, 1900, the lunar calendar), the proletarian revolutionary Zhang Wentian was born. Zhang Wentian is from Nanhui County, Jiangsu Province. He participated in the May 4th Movement in 1919, joined the Communist Party of China in 1925, and entered the Jiangxi Central Revolutionary Base in 1933. He participated in the Long March in October 1934 and attended the Zunyi Conference on the way, which played an important role in establishing Mao Zedong's leadership position. After the founding of the People's Republic of China, he was appointed ambassador to the Soviet Union. In 1959, he was wrongly criticized at the Lushan Conference and persecuted during the "Cultural Revolution". He died of illness in July 1976. Zhang Wentian devoted himself to the revolution in his early years and was an important leader for a long period of time in the history of the Communist Party. He participated in the May 4th Movement in his youth, withstood the baptism of advanced ideas, actively explored the path of saving the country and the people, and joined the Communist Party of China during the revolutionary storm of the May 30th Movement. From then on, he selflessly dedicated his life's energy to the party and the people. In the early 1930s, although Zhang Wentian implemented Wang Ming's "Left" dogmatism and adventurism when he took up the central leadership position, after entering the central revolutionary base area, especially during the Long March, he deeply realized that "Left" adventurism caused great harm to the party's cause, realized that only the correct ideas represented by Mao Zedong could guide the China revolution to turn danger into safety, and resolutely broke with the "Left" mistake. At the Zunyi Conference, he firmly supported Mao Zedong's correct ideas and was entrusted with drafting the meeting resolution, making important contributions to establishing Mao Zedong's leadership position in the Red Army and the Party Central Committee and realizing the party's great historical turning point during the New Democratic Revolution. Zhang Wentian carried out fruitful work in our party's strategic transformation from the Agrarian Revolutionary War to the National Liberation War. During the Long March and after arriving in northern Shaanxi, he actively participated in the struggle against Zhang Guotao's plot to split the Party and the Red Army, and resolutely safeguarded the unity of the Party. After the victory of the Long March, he made arduous efforts to establish the Anti-Japanese National United Front. At the Wayaobao Conference held by the Central Committee in December 1935, he presided over the meeting and drafted the resolution of the meeting. This resolution and the report "On Strategies to Oppose Japanese Imperialism" delivered by Mao Zedong after the meeting systematically elaborated on the tactics and principles of the Party's Anti-Japanese National United Front. After the outbreak of the Xi'an Incident, he assisted Mao Zedong and Zhou Enlai and contributed his wisdom and strength to the peaceful settlement of the Xi'an Incident, the realization of the second cooperation between the Kuomintang and the Communist Party, and the creation of a new situation in China's revolution and the anti-Japanese struggle. Zhang Wentian has made outstanding achievements in theoretical publicity and cadre education. After the Sixth Plenary Session of the Sixth Central Committee of the Communist Party of China, he was mainly responsible for propaganda, cadre education and theoretical research. He wrote a large number of articles to publicize the Party's policy of the Anti-Japanese National United Front and the future of victory in the War of Resistance, inspire the people of the whole country to persist in the fighting spirit of the War of Resistance, and criticize the erroneous tendencies of "Left" or Right in the Party. Under the new situation of the Anti-Japanese War, cultivating cadres has become an urgent task for the party. He pointed out: "We must re-educate and train cadres so that they can understand new policies and adapt them to new requirements. Under his chairmanship, a large number of military cadres who had experienced the Agrarian Revolutionary War, underground party members who had worked in the White Area, and young students who participated in the 129th Movement entered the Marxism-Leninism Institute of the Central Committee of the Communist Party of China and other colleges for training and study. During the Yan 'an Rectification Movement, Zhang Wentian dissected himself with a serious spirit of self-criticism, and also used the spirit of "making up lessons" to go deep into reality, the grassroots, and the masses, investigate and study, deepening his understanding of the rural economic and social situation in China. During the War of Liberation, he went to work in Northeast China and made outstanding achievements in a series of important work such as establishing base areas, mobilizing the masses, eliminating bandits, and land reform, and creatively implemented the central government's line, principles and policies. His exposition on the economic composition of Northeast China and the basic principles for economic construction has important theoretical significance. In the early 1950s, Zhang Wentian went to work in the foreign affairs department. He pays attention to investigation and research and is diligent in analyzing problems. His proposition that embassies abroad should focus on the governments of various countries as their main work objects, that foreign assistance should be within their capabilities, and that diplomacy must be conducted diligently and diligently, is still of practical significance to this day. He is very concerned about the development of my country's socialist economic construction. At the Lushan Conference, with an attitude that the party was highly responsible to the people, he criticized the "Left" mistakes that occurred in the work at that time, and emphasized the importance of adhering to seeking truth from facts, overcoming subjectivism, and promoting intra-party democracy. For this reason, he was treated unfairly. However, he always strictly set himself according to the standards of a Communist Party member, continued to devote himself to the study of the theory and practice of socialist construction, and wrote many reading notes and research manuscripts. During the "Cultural Revolution", he suffered hardships, but he remained upright, adhered to principles, took the overall situation into account, and protected his comrades, demonstrating the strong will and revolutionary integrity of a Communist. In his last years, he wrote manuscripts such as "Politics and Economy under the Dictatorship of the Proletarian" despite his illness, expounding the basic principles of Marxism and proposing a series of important ideas on strengthening the ties between the party and the people, developing social productive forces, and exploring the right path to socialist construction in China. Zhang Wentian has a profound understanding of Marxist theory, a high degree of party spirit principles and a keen political vision. He lived an upright and upright life, selfless and fearless. We cherish the memory of Comrade Zhang Wentian and must learn from his firm belief in the cause of the party and the people. No matter how harsh the environment is or how rugged the road is, we will move forward and unswervingly. Learn from his noble character of daring to uphold the truth and correct mistakes. When practice proves that he has made mistakes, he has the courage to correct mistakes and at the same time he has the courage to adhere to correct opinions. Learn from his spirit of tireless and diligent study, and be good at using Marxist positions, viewpoints, and methods to study and solve new situations and new problems that arise in practice. Learn from his fine style of seeking truth from facts, being modest and prudent, hard work and plain living, persist in going deep into reality, conducting investigation and research, maintaining close contact with the masses, serving the people wholeheartedly, and consciously serving the people as a good public servant.
