The road to Xiongguan is really like iron, but now we are starting from the beginning and it is like a poem written by Mao Zedong. This poem comes from Mao Zedong's "Recalling Qin'e·Loushanguan", written in February 1935. Loushanguan is located in Zunyi, Guizhou. The terrain is dangerous and it is an important pass from northern Guizhou to Sichuan. It has always been a battleground for military strategists. The Red Army fought a fierce battle with the enemy at Loushanguan and finally won the victory. This made Mao Zedong deeply moved and he wrote this poem after the war. The upper part of the poem depicts the magnificent scenery of Loushanguan, showing the poet's calmness when facing difficulties and challenges; the lower part expresses the poet's confidence and determination for the future, reflecting his optimistic spirit. It is really like iron, but now we take every step to cross it from the beginning." The meaning of this poem is: Don't say that the difficult and dangerous Loushan Pass is as insurmountable as steel. Now we must move forward bravely, take steps, and overcome the difficulties again. This poem expresses Mao Zedong's firm belief and courage in facing difficulties, and also reflects his confidence and determination in the revolutionary cause. It has inspired generations of Chinese people to strengthen their beliefs and move forward courageously when facing difficulties and challenges.
