What do you make of Chapter 50 reference to :

十有三

The two logical options seem:

1. 3 out of 10 (but technically leaves one person out)

2. 13 parts (refers to the 4 limbs and 9 orifices as).

While 1/3 would eliminate an odd man out I don't find it supported due to the grammar construction...

but curious as to your tho...
