At the review meeting, the project team listened to the discussion and technical proposal report on the project detailed design and reliability of the project, and fully questioned and defended.

The expert group believes that the project machine tool can meet the process requirements of the key parts of the electronically controlled common rail diesel injection system, and the plan is feasible; the project team has done a lot of work in reliability design, reliability manufacturing, reliable assembly, and reliable use, and the progress has been very great. They are satisfied with the overall progress of the project; at the same time, experts also put forward suggestions on strengthening reliability verification and thermal compensation research; the expert group highly recognizes the project implementation of Jack Machine Tool.

On the 13th, at the Jinggangshan Revolutionary Martyrs Cemetery, I listened to the on-site teaching given by the professor of China's Jinggangshan Cadre College: The Power of Faith, Laying Wreaths to the Martyrs Collectively; Listening to the Red Story Session: "Jinggangshan Spirit from Generation to Generation". The grandson of Wang Zuo; the former deputy director of the Organization Department of the Central Committee and the grandson of Zeng Zhi of the old Red Army in Jinggangshan personally told the story; and the winner of the National May 1st Labor Award, Mao Binghua, an 86-year-old old party member, came to the scene to preach the Jinggang spirit. Everyone was deeply shocked and convinced by Jinggangshan's spirit of "steadfast belief, hard work, seeking truth from facts, daring to blaze new trails, relying on the masses, and daring to win". For all generations, Luling culture shines through the ages. During the review meeting, Jack Machine Tool also specially arranged agendas such as Wang Yangming Academy and Jinggang Red Education, aiming to provide a strong spiritual power for the steady advancement of major projects, to shape the soul of belief in "Equipment and Dream", and to help "Made in China 2025".

It is reported that "Made in China 2025" proposes "three steps": the first step is to enter the ranks of manufacturing powerhouses by 2025; the second step, by 2035, my country's manufacturing industry as a whole will reach the middle level of the world's manufacturing powerhouse camp; the third step By the 100th anniversary of the founding of the People's Republic of China, China's status as a major manufacturing country has been consolidated, and its comprehensive strength has entered the forefront of the world's manufacturing powers.
