Hello YinYangHouse; I have a question about the Mother-Child points chart for the Five Shu Points on your excellent site. When I read for example, Lung (Metal) Mother point is LU9 and Child point is LU5. When I look at the Five Shu Points chart I see LU9 is Earth and LU5 is Water. It looks like a GrandMother - GrandSon relationship.
Please advise if I am reading and understanding this concept properly.
best regards;
bob
