The labor model spirit, labor spirit, and craftsman spirit are rich in connotation, with laborers as their main subject. The value pursuit of the three spirits regarding truth, goodness, and beauty can be summarized as "pursuit of excellence in labor skills" (excellent skills), "pursuit of moral goodness in labor" (moral goodness), and "appreciation of beauty in labor" (aesthetic appreciation). Focusing on these aspects, each spirit embodies the value pursuits of excellent skills, moral goodness, and aesthetic appreciation, but with different emphases and specific manifestations. Thus, the three spirits, in terms of aesthetic appreciation, progress from the labor spirit's "love for labor", to the labor model spirit's "courage for innovation", and finally to the craftsman spirit for "pursuit of excellence". Regarding moral goodness, the progression moves from the labor spirit's"honest labor", to the craftsman spirit's "excellent skills", and culminates in the labor model spirit's "willingness to contribute".
