Since the east is where the sun rises and the rising sun is similar to the processes of germination and ascent, the east is classified as analogous to wood. The weather in the south is hot, similar to the upward flaring nature of fire, thus the south is classified as analogues to fire. West is where the sun sets and as such is similar to the descending nature of metal, thus the west is classified as analogous to metal. The weather in the north is cold, similar to the cold nature of water; thus the north is classified as analogous to water.
