Abstract: Under the guidance of Marxism, the three generations of Saihanba builders wrote green miracles in the desert with their hard work and sweat, and it condensed into the spirit of Saihanba in the new era with the core of“remembering mission, hard work, and green development”. It has made valuable contributions to the construction of ecological civilization in China. By analyzing the importance and necessity of strengthening the education of ideals and beliefs in the new era, we will highlight the importance of strengthening the education of ideals and beliefs of Party members and cadres and young college students in the new era. It is of great theoretical and practical significance to firmly believe in Marxism, practice the civilized concept of green development, explore innovative working methods, and establish a firm belief in perseverance.
