The poem "Shizi" is Lu You's masterpiece, which was written in December of the second year in Jiading, Song Ningzong (12 10 January). At this time, Lu You was eighty-five years old and could not afford to get sick. Before he died, he wrote this poem for his sons. This is not only the poet's will, but also the poet's last voice of resistance.
Lu You devoted his life to the struggle against gold and always hoped to recover the Central Plains. Despite repeated setbacks, it has not changed its original intention. From this poem, we can understand how persistent, deep, warm and sincere the poet's patriotic enthusiasm is. It also embodies the poet's lifelong worries. The poet always holds the belief that the Han nationality must recover the old things at that time and has the confidence to win the Anti-Japanese War. The poet bravely told his son that it was extremely aboveboard and exciting. The deep patriotism is vividly on the paper.
