During the Tang Dynasty (around 800 AD), a well had been dug beside a wall near a famous Buddhist temple that was covered with goji vines. Over the years, countless berries had fallen into the well. Those who prayed there had the ruddy complexion of good health, and even at the age of eighty they had no white hair and had lost no teeth, simply because they drank the water from the well. From this legend, a poem was crafted. a cool well beside the monk's house a clear spring feeds the well and the water has great powers emerald green leaves grow on the wall the deep red berries shine like copper the flourishing branch like a walking stick the old root in a dog's shape signals good fortune the goji nourishes body and spirit drink of the well and enjoy a long life -Tang Dynasty poet Liu Yuxi (772 - 842 AD)
