It means: It's not far from Wan Li to go to the battlefield, and it's as fast as flying.
Excerpt from the original:
Buy horses in the east, saddles in the west, reins in the south and whip in the north. Say goodbye to parents and stay by the Yellow River at dusk. I didn't hear my parents calling for a female voice, but I heard the Yellow River splashing. Say goodbye to the Yellow River and go to Montenegro at dusk. I can't hear my parents calling for a female voice, but I hear Yanshan Hu riding a horse.
Wan Li to Rongji, the mountain is flying. The breath of the new moon is golden, and the cold light is iron. The general died in battle, and the strong man returned in ten years.
Vernacular translation:
Harnesses can be bought everywhere in the market. I left my parents the next morning and camped by the Yellow River at night. I can't hear my parents calling my daughter, I can only hear the sound of the Yellow River flowing. Leave the Yellow River on the road the next morning and arrive in Montenegro in the evening. I can't hear my parents calling for my daughter, but I can only hear the chirping of Hu Bing's war horses in Yanshan.
It's not far from Wan Li to go to the battlefield, and it's as fast as flying over mountains and mountains. The sound of knocking came from the cold in the north, and the moonlight reflected the armor of the soldiers. Soldiers fought many wars, some died for their country, some fought for many years and returned home in triumph.

Historical background:
During the Northern Wei Dynasty, nomadic people in the north constantly harassed the south, and the Northern Wei regime stipulated that each family should send a man to the front. However, Mulan's father was too old and sickly to go to war, and her younger brother was still young, so Mulan decided to join the army instead of her father and began her military life for more than ten years.
Going to the border to fight is a hard job for many men, and Mulan has to hide her identity and kill the enemy with her friends, which is even more difficult than ordinary people who join the army! Fortunately, Mulan finally fulfilled her mission and returned home in triumph decades later.
Because of her great contribution, the emperor pardoned her for cheating the monarch, and at the same time believed that she was capable of serving in the court and holding an official position. However, Mulan refused because she had an old father to take care of at home, and asked the emperor to let her go back to China to make compensation and honor her parents.
For thousands of years, Mulan has always been a respected woman in China, because she is brave and simple. 1998, American Disney Company adapted Mulan's story into an animated cartoon, which was welcomed all over the world.
Mulan Poetry has been included in middle school textbooks and sung by thousands of people in Qian Qian for several generations. Mulan's deeds and image have been put on the stage and will be immortal. Her spirit has inspired thousands of Chinese sons and daughters to defend their country, which is touching.
