Na Jia system, this system is also known as Wen Wang Ba Gua where uses the 10 Stems inverted into the 8 Trigrams and then later can assign them to the 6 lines on the hexagram.

To arrange and memorize the arrangement, we can just simply put it into a Family arrangement.

Yang Stems means the Stems that carry Yang Qi ( the doer, the kick-starter, the leader, the decision-maker, etc), so in total of 10 Stems available, we only take the Yang into this category which is

• JIA (Yang Wood)-- the Father, because the Jia is the leader of the 10 Stems

• BING(Yang Fire) -- the youngest son -- happy go lucky type of characteristic

• WU (Yang Earth) -- the middle son -- the stable and observant type

• GENG (Yang Metal) -- the eldest son -- the courage and the decision-maker type and

• REN (Yang Water) follow the Jia; the Father

Then, we have also had to find the Yang Trigrams in the whole 8 Trigrams available by acknowledging the trigram which has only one unbroken line available: ZHEN, KAN, and GEN plus one special trigram which has all three unbroken lines all together in a trigram which is the QIAN ( the leader).

This trigram arrangement is always a bottom-up, meaning the line on the bottom is the first line formed, follow by the middle and lastly the upper.

So, if you find the only one unbroken line positioned at the bottom, it can also mean ( for easy memorizing) the first son. The only one unbroken line is in the second line means the second son, the only one unbroken line is on the top line means the youngest son.

After we assigned all the Yang Stems with the Yang Trigrams now we have the complete arrangement that:

•Jia (Ren) and trigram Qian are the Father

• Geng and trigram Zhen are the eldest son

• Wu and trigram Kan are the middle sons

• Bing and trigram Gen are the youngest son

This Formation you can find usually in the traditional complete formation (shown on the last image below). This Na Jia Formation also used in manual plotting for IChing Bazi and XKDG.
