What is the main idea for the story "the writing on the wall" by camille dungy

Dungy states her central idea in paragraph 16 when she says, “Scholars are researching the poems, and people and poets like me, who need to believe in the power of poetry to speak beyond the here and now, can stand in front of those walls and understand the power of poetry; to calm, to communicate, to commiserate, and to conserve.” I think that the author is explaining how people were able to connect their experiences through poetry. Immigrants were treated poorly but in particular, the Chinese. They used poetry to express how they were feeling. Other immigrants read these poems that were etched on the wall and were able to relate to their feelings as well. Lonely, weary, lost.  Later on in history, people who discovered this art worked on translating it. Translators were able to help others that didn’t go through the experience of immigration connect and understand. The author tells the reader how poetry is powerful and helps “calm” other immigrants, “communicate” with people today, help people “commiserate,” and “conserve” this sacred, memorable art.
