I want to express my deep love for the Chinese nation with my blood. ?

The whole poem is: The spiritual platform has no way to escape the divine arrow, and the storm is like a rock, darkening the hometown. I wish you could see the cold star in Tsuen, but I recommend Xuanyuan with my blood. The last sentence in Lu Xun's poem "Self-Inscribed Portrait" mainly expresses the meaning that I want to use my blood to express my deep love for the Chinese nation. Donate blood today, which has become Mr. Lu Xun's wise saying.
