中学语文课本第三册贾谊的《论积贮疏》中有这样一句话:“失时不雨,民且狼顾,岁恶不入,请卖爵子,既闻耳矣,安有为天下阽危者若是而上不惊者?”课本注释“岁恶不入,请卖爵子”条为“年成坏,不能纳税,(朝廷)卖爵位(来增加收入),(百姓)卖子女(来度过日子)。卖爵,汉朝有公家出卖爵位以收取钱财的制度。” In Jia Yi’s “On Product Storage and Sparse” in the third volume of Chinese textbooks for middle schools, there is such a saying: “When it is not time to rain, the people and the wolf take care of us. If the person who is in danger is not to be frightened? “The textbook notes “If you are in an unfathomable age, please sell the grandchildren.” The article states that “Years are bad, you cannot pay taxes, (the court) sells your title (to increase your income), and (the people) sell your children. (To spend the day.) To sell the Grand Prix, there is a system in which the public sells the knighthood to collect money."
