The first line:
Checked by a metal brake: pure fortune.
There's a place to go, but misfortune
will be seen. A weak pig will surely falter.
The second line:
The wrapping has fish. No fault.
Not gainful for guests.
The third line:
Buttocks without skin: one walks uneasily.
Harsh, but no great fault.
The fourth line:
The wrapping has no fish:
the start of misfortune.
