First of all, to correct it, Mencius is a philosopher and a writer, but his works are prose, not poetry. You may have confused Meng Jiao's poems with his.
2, the original poem:
A traveler's song
Meng Jiao
The mother used the needle and thread in her hand to make clothes for her long-distance son.
Before leaving, I had a stitch for fear that my son would come back late and his clothes would be damaged.
Who can say that a filial child like the weak can repay his mother's love like the sunshine in spring?
3. Translation:
A loving mother makes clothes for her long-distance son with a needle and thread in her hand. Before leaving, he sewed a needle tightly for fear that his son would come back late and his clothes would be damaged. Who can say that a child's filial piety as weak as grass can repay the kindness of such a loving mother as Chunhui Puze?
