He presides over the Tenth and final Court of FENG-DU, the Chinese Hell.
After suffering the most awful torture for your earthly crimes, you will no doubt be extremely glad to get here. Escape! Freedom! At least, of a sort. Taking into account your crimes and repentance, ZHUANG-LUN-WANG will decide what form your next incarnation will take.
Most people will go up or down a few rungs of the spiritual ladder. Most people are reborn into a situation not too different from their previous one. But if there’s still too much evil in your soul, you may find yourself reborn as an ape, a dog, a pig or even a slug. We’re surprised facts like these are not more widely publicized. It would greatly reduce the crime rate.
Once ZHUANG-LUN-WANG has decided your fate, along comes MENG-PO with her Tea of Forgetfulness. One sip and you lose all memory of your previous life. You also forget your time in Hell, which means you are free to make the same mistakes all over again in your next life.
Then you are strapped to the Wheel of Life and taken for a spin. After a short spiritual pep talk, you are sent wheeling into your next incarnation. And the very best of luck.
