This variety of oolong got such a dissonant name because the farmer who grew this tea was afraid that a wonderful fragrant bush would be stolen from his garden. So he came up with such a repulsive name. According to another version, the name came from the tea garden, in which bushes grow, from which later this variety was produced. The garden is called "Ya Shi Tu", which means "soil of the color of a duck droppings".

Of all the varieties of Phoenix Oolongs, this one is distinguished by the strongest aroma of orchids, which does not go away even after 7 brewings. It is interesting that the tea, harvested at different times of the year, has a different character of taste and aroma, so at first it may even seem that these are all different teas. Now this variety is more common with less heat, which enhances the aroma of flowers and makes the variety more popular with the inhabitants of China.
