Prince Gao Changgong of Northern Qi possessed a peerlessly handsome face, yet it was his benevolence that truly won the hearts of his soldiers. In the chaotic era, as his loved ones fell victim to the turmoil, he was awakened to the creed of "ending war with war." Donning a mask, he led five hundred cavalry to shatter the Northern Zhou army of one hundred thousand, lifting the siege of Luoyang. At the city gates, he removed his mask, invigorating the entire army. His deeds were immortalized in the song "Prince of Lanling Entering the Battle Formation," celebrated throughout the ages.
