Lu Ji (known as Rikuseki in the Japanese tale) was the son of the politician Lu Kang. One day when he six, his father took him to visit the general Yuan Shu. The general treated his guests to mandarin oranges and the sweet juice made Lu Ji think of his mother–he wanted her to try the delicious fruit. He stuffed two of the fruits into his sleeve, but when he stood to leave, the oranges rolled from his sleeve onto the floor. When Lu Ji admitted that he had wanted to share the oranges with his mother, the general was not angry. In fact, he was impressed by the boy’s devotion to his mother.
