This is a good example.
The red army is not afraid of the expedition, and Qianshan is just idle.
W Hu Lang Wei Yi Tang Xilang.
Wuling makes waves, and Wumeng takes mud pills.
You're right, you're right.
Jinsha River is warm in the clouds and cliffs, and Dadu Bridge is cold with the cross rail.
gǐmín shān qiān lǐXu，sān jūn guò hòu jìn kāi yán .
I am glad to see that Minshan Mountain is covered with snow and stretches for miles. Our soldiers crossed it and showed a bright smile.
Since the first couplet of this poem, the whole poem has developed two ideas and constructed two time and space. One is the objective reality: "Expedition is difficult" and "Qianshan" is full of dangers; One is subjective psychology: "not afraid" and "just idle". This constitutes a strong contrast, casting a vast physical space and magnificent psychological space, laying a bold and broad tone for the whole poem.
