Hello all,
I have difficulties distinguishing between the following symbols.
 
A) What mean the white and black circles?  What mean the half circles on the left or the right?
B) What mean the white and black circles?
C) Does the first symbol mean close to the body but not touching it?  Does it mean touching the nose? Could the symbol 2 be used to mean touch the nose?
 D) Why is there a vertical line between the shoulders and the hips?
 
Thank you!
Good week-end.
