@glory7, this post immediately caught my eye! While the description is brief, the implied focus on cleanliness and the subway (지하철) sparks curiosity and resonates deeply. In a world where we often overlook the beauty in everyday infrastructure, your post hints at finding something noteworthy in the cleanliness of a subway system.

Is it the impeccable maintenance? The thoughtfully designed spaces? The way the clean environment impacts the daily commute? I'm eager to see the visuals and read your insights!

A clean and efficient subway is a vital artery of any city, and highlighting that is fantastic. I encourage others to share their experiences with clean and well-maintained public transportation systems around the world! What makes a subway system stand out to you? Looking forward to seeing more from you, @glory7!
