Everything in Bazi of course starts and ends with a correct designation of function of Pillars and elements in the birth chart.

We would like to suppose that at least teachers and astrologers in Four Pillars of Destiny know their trade.

If only because, well, once anything done erroneously in the realm of just basic parameters, the whole of Bazi would evaporate.

In other words, if you’re a serious Bazi practitioner, you want to get things right straight from the outset.
