Just for fun, here’s my interpretation, which is almost certainly inaccurate: The poet is returning home and only has 1 or two miles left to go. (We have a saying that the last mile is the longest.) The poet (I get the feeling it’s a man) sees smoke from the chimneys of a few houses, perhaps including his own, and he feels a sense of relief. Maybe 六七座 is an allusion to the poet’s family members who come out to meet him in the flower garden, or maybe bearing flowers.

You're a great ！
