The first line:
Pit within a pit.
Entering an underground vault:
misfortune.
The second line:
The pit has dangers.
Inquiries get little.
The fourth line:
A bottle of wine, a bamboo basket,
and two earthenware vessels offered simply
through a window. In the end, no fault.
The fifth line:
The pit is not yet flooded to the brim.
No fault.
