To put it simply, this sentence comes from the regular script works of calligrapher Tian Yingzhang. The original sentence is roughly: "Indifferent to Zhi Ming, quiet and far-reaching; After the collection of poems was opened, it was handed down diligently. As a calligraphy work, it is intended to convey that in this materialistic era, we need to have an indifferent and pure heart, less glitz of life and more spiritual pursuit beyond material things.
Calligraphy analysis:
The couplets in this group of sentences are "indifferent to your ambition, quiet and far-reaching" from An's Annotation on Huai Nan Zi: "So don't be indifferent to your ambition, not quiet and far-reaching." Later, Zhuge Liang also quoted it in the Commandment. It means: Only when you calm down and think nothing, can you define your ambition, and only when you get rid of external interference can you achieve your lofty goals.
The second part of this set of sentences: "Poems are passed down from generation to generation through diligence", which is similar to Su Shi's Ming of Sanhuai Hall in Song Dynasty: "Faithful poems are handed down from generation to generation for a long time to help the world", and the consciousness is to pass on reading as a good habit to future generations and the spirit of hard work to future generations of the family.
