I Ching is an ancient method of Taoist Chinese divination. I've got no idea how you do it with yarrow stalks, but it amounts to the same thing as throwing three coins six times in a row, assigning 2 to heads and 3 to tails, giving you six numbers from 6 to 9. You represent a 6 or a 7 with a broken line and an 8 or 9 with a solid line (or it might be the other way round, I can't remember). This gives you what's called a hexagram, and there are 64 possibilities. Each one also has a number of 'changes', depending on whether any line is the more common 7 or 8, or the less common 6 or 9. The responses are written in a book called the Tao Te Ching or Book of Changes, and amount to the usual vague gubbins you get in these kinds of things, which can apply pretty much equally to anyone.

That's not to say it doesn't work, of course - I reckon it works as well as any other divination method, by essentially allowing you to access subconscious knowledge or emotions, like a Rorschach test. We pick out the bits that apply to us and discard the rest.
