His most famous battle however was the rescue of the siege of Jinyong (金墉, near modern Luoyang) in 564 A.D. Gao Changgong led only 500 cavalrymen and fought through an army of Northern Zhou, which was attacking the city with 100,000 soldiers.

[5] The song and the dance are long lost in China; however, it was introduced into Japan during the Tang dynasty with Lanling known as Ranryōō (蘭陵王 (らんりょうおう), Ran-ryō-ō), and is still being performed in some ceremonies today.

To avoid the emperor's suspicion and jealousy, Gao Changgong often pretended to be sick, staying away from wars and politics.

In 1999, within the cave of Longmen, a message was found carved into a statue, indicating that the Prince of Lan Ling had living descendants.

Gao Changgong is one of the 32 historical figures who appear as special characters in the video game Romance of the Three Kingdoms XI by Koei.

Gao Changgong appears as a character in Fate/Grand Order as "Prince of Lan Ling" and is voiced by Mori Nanako.
