Why do we need gold and water when the five elements are short of water?

Hello dear friend:

The Five Elements produce restraint and turn into Yiji

When metal is prosperous and fire is achieved,

it becomes a vessel.

Metal can generate water,

More water and metal will sink;

Strengthening metal will bring water,

it will defeat its front.

Metal can overcome wood,

There is too much wood and metal is lacking;

When wood is weak and metal meets,

it will be chopped down.

Metal depends on the soil,

If the soil is rich, gold will be buried;

Soil can produce gold,

If there is too much gold, the soil will change.
