Chinese entrepreneur An Yanshi is convinced he has found the key ingredient to produce the world's most expensive tea -- panda poo.
The former calligraphy teacher has purchased 11 tonnes of excrement from a panda breeding centre to fertilise a tea crop in the mountains of Sichuan province in southwestern China, home to the black and white bears....
The tea aficionado got the idea to use panda faeces as fertiliser after attending a seminar last year where he discovered that the bears absorbed less than 30 percent of the bamboo they consumed, excreting the remaining 70 percent.
An showed AFP a glass jar of fresh-looking panda faeces, which he uses to fertilise two tea plants in his office, noting the "quality" and "green" colour of the dung.
Representatives of Panda Express could not be reached for comment.
