Our people have known and used the ear for a long time. During the Qi and Liang Dynasties in the Southern Dynasties, Tao Hongjing, a famous doctor, was recorded in "Bielu of Famous Doctors" in the name of "Di Er". This is the earliest record of ears in the world. Take the medicine first, then eat it. In ancient books such as compendium of materia medica, medical code, potherb recipes and local chronicles, there are descriptions about the distribution, medicinal use, consumption and collection of auricularia auricula. Huang Tingjian, a famous poet in Song Dynasty and a Taoist priest in the valley, once wrote poems such as Ode to Vegetables to praise it. In the Southern Song Dynasty, Zhu Bian wrote a poem, "Local dishes are nine summer treasures". Its cooking method, seen in ancient times, is the first to promote Yuan Mei's "Suiyuan Food List" in the Qing Dynasty: "Carefully select rice (that is, ground ear), cook it until it is half rotten, and simmer it with chicken soup and ham soup". At the end of the Qing Dynasty, Xue's Su Wen lue was unique: "Take it as thin as a small grain of rice, boil it in water, drain it, and simmer it in broth, which is very clear. I add small tofu blocks, which are both rigid and soft, black and white, delicious and beautiful. " Tremella has been used as a tribute and as a royal meal. On Xuan Tong's menu, there is a dish called "Diced Duck Eggs and Gexianmi". Puyi's "My First Half Life" is described in this way. It's really delicious in the wild vegetable competition.
