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 third line:
Buttocks without skin: one walks uneasily.
Harsh, but no great fault.
The fifth line:
Like a gourd surrounded by willows,
and held in place,
there comes a falling from heaven.
The sixth line:
Copulating with a horn. Remorse.
No fault.
