Third Master Ding was a man of presence.
In these years, any trade that involved professional techniques somewhat required a bit of showmanship.
Because ordinary people don't understand your trade well enough; they don't know by what specific standards to judge your professionalism.
So, the older and whiter a doctor's beard, the more in demand he is.
Having lived to such an age without being killed by a patient, that's the best proof of ability.
Businessmen must look sharp on the outside when dealing, no matter how much silver they owe behind the scenes; they must dress impressively and carry themselves with authority.
Fengshui masters are the same.
You can claim to be poor, using the excuse that your profession is destined to encounter great misfortunes and therefore you dare not covet wealth.
But you absolutely cannot be unlucky, nor can you be outsmarted by others. If you can't even figure out your own fate, why would anyone trust you to examine their fengshui?
