During the Han dynasty people thought a poem should be meaningful to later generations. How does this poem meet that goal?

one of the main reasons was definitely slavery. back in 1861, republican abraham lincoln was elected and ended up being a major influence in the slavery business. slavery greatly affected the texas economy because back in 1845 during the annexation of texas, slaves became a big part of the texas population. many texans that were in favor of the secession influenced groups through party ties.

i think the answer is the one about environmental and social health.

hope this

i see, would you mind putting it as one?
