There is a poem about children planting melons in the shade: children and grandchildren are not prepared to farm and weave, but also learn to plant melons in the shade of mulberry trees. "Children and grandchildren" refers to those children. They have been in contact with and love labor since childhood, so they "learn to grow melons under the shade of mulberry trees" and learn to grow melons under the lush mulberry trees. This is a common phenomenon in rural areas, but it is quite distinctive.
