Maitong Grass is recorded in the Compendium of Materia Medica as an excellent herb to maintain health, the main part of Maitong Grass is its tuber, and in Henan, people habitually call Maitong Grass "Yu Yu Liang", "Yu Leek", "These appellations are related to the historical legend of maitong grass.

Legend has it that in ancient times, the sage Dayu wasted a lot of effort to manage the scourge of flooding, and finally ended the flooding, so that people could finally live in peace and no longer suffer from floods. Since the flooding was over, people were able to work normally, and without the flooding, the crops and plants in the fields grew very well, and the people were blessed with a good harvest, but this harvest also brought troubles, as there were too many grains, and the people had no way to eat all of these grains. Seeing this situation, Dayu ordered everyone to pour the remaining uneaten grain into the river. After a while, people found that a kind of grass grew in the river where the grain had been poured, and for this reason, people called this kind of grass "Yuyu Grain". The plant called "Yu Yu Grain" is what we call Maidong Grass, and later, because this plant grows in Yuzhou, and the leaves of Maidong Grass are very long and narrow, and look very much like leeks, so people also call this plant "Yu Leek".
