A few days ago, a friend asked me to do KYC, and that's when I realized my ID card was missing.

Since I have a driving test coming up, I need to find my ID card as soon as possible.
My last memory of my ID card was when I took the second part of the driving test. I have no memory of it after that.
My prediction:
I searched the house but couldn't find it, so I set up a Qi Men Dun Jia chart to ask where my ID card was and whether I could find it. The chart is shown below.

I asked the first question.

Where is my ID card now? Kan Palace. If it's at home, Dui Palace. If it's lost outside, Kun Palace.
At the time, my judgment was: Kan Palace was void, so I looked directly at the relevant palaces, Dui and Kun.
Dui Palace, upper trigram. The pattern was Geng over Ren, Jing Gate was blocked. My interpretation was that the longer the time passed, the less likely it would be found at home. Combined with the blocked Jing Gate, the probability of it being at home was low.
Kun Palace, upper trigram. The useful spirit of the ID card, Ding, just appeared. My first impression was that the ID card was lost outside.
What struck me at the time was Bing over Wu, "the flying bird falls into the cave." This pattern indicates that the ID card could return to me.
My judgment then was: the ID card was lost outside, not at home, but may come back in the future.
Based on the last time I saw my ID card, which was in the assistant coach's car, I asked if the assistant coach could check his car. He said he was in Shanghai and would help me look when he returned in a few days.
At the time, I should have asked a follow-up: If it was lost outside, could the ID card be found? I should have asked a set of questions like this.
But I felt my mental energy was not enough. In my logical and experiential thinking, an ID card lost outside is hard to find...
