What is missing from the Five Elements at 3:30 pm on October 23rd of the lunar calendar in 1998?

The five elements lack fire and there is relatively little metal.

Your yen is Renshui, which is Yangshui. So fire is just not needed. What is lacking does not need to be replenished. Because it’s not that whatever the five elements lack must be supplemented, but it depends on whether they like to use the gods.

People with a strong water character have a gentle personality, so you should be more aggressive. You can add some gold, gold generates water, which is good for you. To replenish gold, you can wear white clothes or some gold jewelry.
