Bing Xin chose a paper boat as an intermediary to express her infinite yearning for her mother from the perspective of a child, and used it to show people the image of wandering and helplessness. Then express the author's deep attachment to his mother and motherland.
Meng Jiao highlighted and praised the greatness and selflessness of maternal love by recalling a seemingly ordinary scene of mending clothes before leaving, and expressed the poet's gratitude for maternal love and his deep love and respect for his mother. Meng Jiao's ancient poem Ode to a Wandering Son was originally made by a loving mother with thread in her hand, making clothes for her wayward son. She sewed them carefully and repaired them thoroughly, for fear of delaying his return home. However, how much love an inch of grass had brought three spring rays, which was similar to the emotional expression of a paper boat written by Bing Xin.
