This poem," When the boat comes to the bridgehead, it will cross naturally ", came from the Tang Dynasty poet Bai Juyi's " Fu De Gu Yuan Cao Farewell." The whole sentence is: "The years of separation from home have been half worn away. Only the spring breeze of the mirror lake in front of the door does not change the old waves." This poem described the poet's nostalgia for his hometown, which had never changed after leaving his hometown for a long time. Among them,"the boat will cross the bridge when it comes to it" was the poet's sigh and blessing to his hometown when he bid farewell.
