This passage from Pearl S. Buck's The Good Earth carries a deep cultural and symbolic significance. It illustrates how names are not just identifiers but are intrinsically connected to identity, heritage, and societal roles. The boys, initially called only by their birth order, receive names that affirm their familial lineage and social status—names chosen deliberately by an old teacher who understands the importance of connections to their father’s occupation. This naming acts as a rite of passage, marking a transformation from vague familial roles into distinct individuals defined by the source of their wealth and livelihood.

The use of the word 'Nung,' meaning one whose wealth is from the earth, beautifully portrays the intimate relationship between the characters and the land. It emphasizes the importance of agriculture and the rural way of life in the narrative. Their names are a symbol of their inherited bond to the earth, reflecting a worldview where identity is deeply rooted in nature and labor. This theme resonates universally, reminding us of the inherent value in understanding one's roots and the significance of the environment in shaping who we are.

Moreover, the passage touches upon the role of community and tradition—how names given by a respected elder carry weight and meaning. It is through this act that the boys find their place and purpose. This scene, thus, is not merely about naming but about honoring heritage, embracing destiny, and acknowledging the profound connection between people and the land that sustains them.
