I am very happy to answer your question about "Don't ask the teacher's name when the world is chaotic." This sentence comes from the poem "Climbing Feilai Peak" written by Wang Anshi in the Song Dynasty. It means that in the world, people have lost their original beliefs and no longer pursue the true name of the Taoist priest.
This poem uses "red dust" to refer to the hustle and bustle of the world, while "original intention" represents the original belief and pursuit. "Don't ask the teacher what his name is" means that people no longer pay attention to the name and identity behind an individual's identity, but pay more attention to the ideas and wisdom he imparts.
This poem is profound and expresses Wang Anshi’s thinking about people’s loss of ideals and beliefs and the more important pursuit of truth. It reminds people to maintain their original intentions in the noisy world of mortals and stop paying too much attention to external forms.
