Wine debt, because there is no money to buy wine and credit. Ordinary, ordinary, often. Travel everywhere. The poem expresses how time flies, the geometry of life, and one should eat, drink, and be merry in time, which reflects the poet's specific mentality of trying to get rid of ideological repression when his ambition and career encounter difficulties. The sentence "Life is seventy years old and rare" is transformed from the old saying "Life is a hundred years old and seventy people are rare".
People who buy wine on credit (people who aim high) are too common and everywhere. Why bother about having no money to buy wine (people who aim high)? People who can live to 70 years old are rare since ancient times. Life is only a few decades, so we should eat, drink and be merry in time.
