Tou wo yi mugua, bao zhi yi qiongju. Fei bao ye, yong yi wei hao ye. “A quince was thrown to me. I gave back a red jade pendant. It was not a repayment. It was so that we would always be friends.” The ode Mugua, in the Airs of Wei of the Book of Songs, repeats this in three verses. Each time a piece of fruit is answered with jade.
The traditional Mao preface reads the poem as an expression of thanks. After the state of Wei was defeated by the Di, Duke Huan of Qi rescued it and gave it carriages, horses, vessels and clothing. The people of Wei “wished to repay him generously, and made this poem.”
