According to the makers of Chami Tea (Ceylon Royal Teas Ltd)..."A leaf fell from a nearby bush, fell into the cup of hot water 'Shen Nang' was sipping. He tasted the improvement over plain boiled water - thus began tea drinking. That's all now history".
So why aren't we drinking shen, or perhaps nang?? "A cuppa shen please" or perhaps "May I have some Earl Gray nang please".
Ah well, 'history is what you make it, and if you don't, then someone else makes it for you.
And I wouldn't change that for all the shen nang in China!
