For a time, there was an endless stream of doctors from all over the country, but they were all used as ginseng tonics, but they did not work. One day, a white-haired old man unveiled the list of medicines, claiming that he was not offering a reward, but for the sake of the prince and the country. The king said to the old man, "you can learn from it sincerely, but if the medicine does not work, you are afraid of being bullied." The old man said with a smile: "the prince is young and tender, and the medicine for tonifying the disease needs to be done step by step." I have a medicine that will take effect in a hundred days. " So the prince took the slender, yellow-and-white grass roots offered by the old man. Three months later, the fruit was plump and unstained. At this time, the king believed what the old man said.
