I had watch a movie staring Jet Li with a title "Revenge Of The White Snake" a Chinese mystical movies which base on Madame White snake legends.Its was a fun movie to watch even though the storyline differ but entertaining and adventure's with more Kung Fu flick.So I did a little research and found that the story revel around the Chinese folklore legend dated back to Ming Dynasty.
Lu Dongbin, one of the Eight Immortals, disguises himself as a man selling tangyuan at the Broken Bridge near the West Lake in Hangzhou.A boy called Xu Xian buys some tangyuan from Lu Dongbin, not knowing that the tangyuan are actually immortal pills. He does not feel hungry for the next three days after eating the tangyuan and is so puzzled that he goes back to ask the seller.Lu Dongbin laughs and carries Xu Xian to the bridge and flips him upside down, causing Xu to vomit out the pills into the lake.
