I am glad to answer your question about "What's the name of Mo Wen's first teacher in the world of mortals". This sentence comes from Wang Anshi's poem "Climbing to the Wind" in the Song Dynasty, which means that people in the world have lost their initial beliefs and no longer ask the real names of scholars.

This poem refers to the hustle and bustle of the world through "the world of mortals", and "initial heart" represents the initial belief and pursuit. What's Teacher Mo Wen's Name means that people no longer pay attention to the names and identities behind individual identities, but pay more attention to the ideas and wisdom they convey.

This poem is meaningful, expressing Wang Anshi's loss of human ideals and beliefs and his more important thinking on the pursuit of truth. It reminds people to keep their initial heart in the hustle and bustle of the world of mortals and stop paying too much attention to external forms.
