During the war, everyone was fleeing, and one person was seriously ill, with fever and blood in his urine, and he couldn't really run, so he could only resign himself to his fate at home with his wife.
One night, the wife was boiling medicine for her husband when a ragged soldier suddenly broke in. The soldier told the couple that his name was Bai Wei, and because he was chased and killed by enemy soldiers, he fled all the way to this place. The couple were both kind people, and when they saw that the soldier was pitiful, they didn't think much about it, so they found him a set of clean clothes for the soldiers to change into, and burned the dirty clothes before. Not long after, a group of men and horses entered the house and questioned the soldiers' whereabouts. The wife was calm and calm, and kept shaking her head to say that she had never seen the soldiers, and told them that her husband was seriously ill and bedridden, and had just invited a doctor to treat her husband. When the people came to see that they did not find anything, they smashed all the belongings that could be smashed in the husband and wife's home, and left with a scolding grin.
The couple's life-saving grace touched the soldiers who were killed, and when they saw that the life-saver was seriously ill and bedridden, the soldier, who was a little skilled, examined him carefully and told the woman that he could treat the man.
The next day, the soldiers brought back a large bundle of herbs, told the woman how to take it, and then hurried away. The patient's wife fried the medicine according to the method told by the soldier and fed it to her husband. The husband ate for a month, and the illness miraculously improved. Later, some people also suffered from the same disease as men, and the couple told the sick person how to use the drug, but they never knew the name of the herb. In order to commemorate the life-saving grace of the soldier Bai Wei, the couple named this herb "Bai Wei", which has been used to this day.
