Radical:

Obviously, this is the 手 radical.

The phonetic is 卦, which is two 土 (earth) and a divining rod (卜). The piled-up earth represents a wall. So this shows a divining rod leaning against a wall.

Add 手 (hand) and you get the idea of someone leaving that rod there. Perhaps they hang it on the wall. References:
