The most recent years where a "Hidden Combination" and other combination took place in my own chart was 2004, 2005 and 2006. I'll also give an impression on what has happened this year so far too for comparison of "Obvious" and "Hidden" combinations.

First looking at the chart itself to identify it's own Use God first. I will say that because the Day Master has no support from the Branches that it can draw upon, and that the "Seperated Clashes" between the Month and Hour Branch, and the Year and Day Branch losing their Hidden Stem properties from the clash. It has no Support (印) or any Sibling (比) element. So it is extremely weak.

With Wood (Power) in Season, and appearing the in Day Branch as well, but being surrounded by (weak) Metal, the chart can not be a Follow Power (Wood) chart. And with Wood in Season and not that weak in numbers, the chart can not follow Metal either. Even more impossible for Water because only one in chart. Since all three weakening elements (Metal, Water, Wood) are in the chart, the chart can only follow all three instead. So the Use God is Water (Wealth), with Metal and Wood as Favourable. And Earth as Avoidance God (忌神) and Fire as (忌神) suuport.

Back to the chart, in 2004, in the Luck Period of 戊子, which for me represented Wealth and Girls. The year of 2004 was also 甲申, which "Obvious Combined" with my Day Stem, and "Hidden Combined" with my Day Branch.

The events of 2004 were:
* Mum Broke her arm around March. By the Annual Year Clashing the Month Pillar of my Chart, which affected my mum.
* I had a "hidden" or "secret" relationship which didn't really blossom with a girl. The Annual Year "Obvious Combined" with the Day Master, and many people saw me and the girl as a possible couple. The "Hidden Combine" made the relationship something that was really just between me and her. It was not public, we just let it develop, but she knew and I knew it was there.
* Did not really work either, and never really found work when looking for it. This was likely due to my own choices at the time, but likely due to the "Injury God" (傷官) being enhanced at the same time as the Power in the chart (正官).

In 2005, the Luck Period was 戊子 and the Annual Year was 乙酉. Which formed an "Obvious Combine" with the Month Stem, and a "Hidden Combine" with the Month Branch.

The events of 2005 were:
* Flew to HK in the Summer. I believe this is due to the "Food God" (食神) and the "Injury God" (傷官) being formed from the Annual Year combination.
* Certain people in my family's life "moved on". Either passing away, or left. Again, likely due to the "Food God" (食神) and the "Injury God" (傷官).
* Was given some information by a Master in Hong Kong. The "Food God" (食神) and the "Injury God" (傷官), represents intelligence and knowledge to a "Follow" chart.
* The girl that I had a private relationship with had a big argument and nearly went seperate ways. I mended the bridges in this year. She said she still liked someone else from before and didn't want to give me chance now. The "Food God" (食神) and the "Injury God" (傷官), although representing change, also supports the Water in the chart, which is also the Money and Girls element in this chart which was why I mended bridges.
* Started work at a local charity without my father knowing that I was helping them. This was more due to that Master in Hong Kong telling me to help. This is probably the "Hidden Combination" in effect, as my father to this day does not know I worked for that charity. So it was "Hidden".

In 2006, the Luck Period was 戊子 and the Annual Year was 丙戌. Which "Obvious Combined" with the Year, and formed the "Metal Direction Combine" with the Year and the Hour of my chart.

The events of 2006 were:
* Worked till Nov 2006 for the charity, but still occasionally went.
* Strained relationship (friendship) with the girl, I continued to mend any bridges as best as I could. But she just seemed to burn them quickly without caring. The bridge mending by me was probably because of the "Obvious" Metal Directional Combination with the Year and the Hour, so I kept mending the bridge that she broke between me and her (the relationship). But she was also hurting me too (because the Annual Dog and my Day Branch also became Fire Support) by pretending nothing happened before, which made me not feel very good. So she became a sore point in my life instead of being a happy spot.
* Made some new friends. This is due to the Earth (Friends) combining with the Year and the Hour of my chart, so I made many new younger friends and much older friends at the charity and they were all very nice to me (All turned to Metal).

In 2007, the Luck Period was 戊子 and the Annual Year is 丁亥. The Annual Year Stem combines with the Water in my chart (Wealth and girls) and becomes more Wood. But not as good because no Water to mediate the Wood and Metal fighting. The Annual Year Branch of Pig also "Obvious" combines into my Month Branch, and "Half Combines" with my Day Branch.

The events so far in this year are:
* Finally had one big argument with the girl I had the "Hidden" relationship with, and walked seperate ways. Because she "Was not going to let a relationship happen" between us. Currently do not talk to each other. This happened in March, in the second month.
* Starting business. Not quite done yet.

So as you can see, when there was periods of "Hidden Combinations", "Obvious Combinations" also happened, and the same the other way around. But not always when "Hidden" or "Obvious" combinations happened were things always good, or always bad. Seeing the favourable outcome also influenced what happened.

Hope this has been of help for you. If you see something I may have done wrong, please do tell me.
