There you have the basics of the Korean family structure.
An interesting cultural note: relationships have numeric “points.” There are zero “points” between a husband and wife. Between a parent and child there is one “point” of relationship. Brothers and sisters have a “two-point” relationship.
The relationship between a child and his/her father’s brother is a total of three points (one for the parent, two for the parent’s brother.) This is reflected in the name for the unmarried paternal uncle,
which starts with the syllable
, Korean for "three."
