Hi
@Furbi ,
Sometimes, some translated terminology I'm not familiar with, but I am guessing "host" here means Day Master.
If so, then Day Master is 辛 metal.
Seal, I understand, because it is a direct translation of 印.
In ancient China, if one possesses an Emperor's Seal, the greatest of 印, he or she cannot be imprisonment and/or executed.
Hence, seal = protection, which also means the element that supports the Day Master element.
In your case, since Day Master is metal, earth grows metal, hence earth is the seal/support element.
Your Day Master is mostly surrounded by earth supports, which I think is the meaning behind "host location is all seal".
If you look at your chart as a whole, 50% of it is filled with seal/support, which is a lot.
Correspondingly, the strength of the remaining elements will be lesser.
So the idea is that support/seal will play the greatest influencing force in your life, unlike say...wealth or friends, for example, because they are governed by wood and metal for you, which are lesser than seal/support.
So likewise, at work, you will more likely ride on the effects of strong seal/support.
Hence "your work depends on seal".
Now, what is seal/support?
It is basically anything that aid you, i.e. protect, guide, help, nurture, grow.
So that covers mother, learning, medical treatment, mentors, people to come to your aid in times of need, ethical thinking, self-reflection, religion, sleep to recover energy, house, reputation...the list goes on, as long that activity or category plays an intended role in supporting you.
Do note that in Bazi there are certain fixed elemental interaction rules to follow.
In this case, I am talking about combines.
Your 戊 and 癸 forms a fixed combination pair.
Your 未 and 午 forms another fixed combination pair.
When 2 words combine, their energies are essentially locked away and can be assumed to be lost to the chart.
So by default, you lose 2 seal/support, but thankfully, you have plenty, so you still have 2 more.
But do take note of meaning behind the losses.
午 as fire, is a suppressor of metal, so as a controlling element, it represents things that control you, like your work or male spouse if you are female.
For it to be combined with a seal/support and have a detrimental effect, it suggests to me that you might have a tough time following orders or accepting instructions when you don't believe those are the right way to do things.
癸 as water, is the output of metal, so it represents your ability to express yourself.
Combining with seal/support and having a negative outcome suggest to me that you are not someone who does things impromptu, ad-hoc, in the moment.
You are likely to consider many factors before acting, especially when it is important.
Some might say you overthink things.
An example of the above applied to work: You might be giving yourself unhappiness by over-considering things (loss of seal/support) which is hampering your productivity (loss of expression energy) and ability to perform at work (loss of controlling energy).
Your strength is that you will still likely receive help more easily than others, probably has a supportive family, probably had a good education.
These are still very useful things in life that can propel you forward, even when lacking expression or work luck.
You are very likely to have a good network of friends, as your earth grows the remaining 酉 metal healthily.
Metal being the same as your Day Master, represents affinity with peers.
All that being said, the outcome can still be very different because there are the changing elements of the rolling decade and annual luck pillars to factor in.
