Under China's political and cultural traditions, there are only hierarchies, only up and down, only superiority and inferiority, only masters and servants, with no room for humanity or humanistic feelings. In 564 AD, during the time when the Northern Zhou army was approaching the city, Gao Wei's father, Gao Zan, was still alive. King Lanling Gao Changgong received orders and, together with Hong Luguang mentioned earlier, participated in a major battle. This battle took place at Mang Mountain, where both sides repeatedly stalemated, and the fighting remained intense. In this deadlock, the situation was clearly unfavorable to King Lanling Gao Changgong and Hong Luguang's side. At this moment, King Lanling put on a mask, disregarding life and death, leading his 500 personal soldiers straight into the enemy formation. He was resolute and fearless, charging ahead on horseback into the depths of the enemy's central position. The 500 knights followed closely behind, shouting as they charged, instantly turning the tide of the battle and ultimately achieving victory from defeat. As a result, King Lanling's reputation soared, and at that time, a song called "The Song of Lanling King Entering the Battle Array" spread among the Northern Qi army. This song even influenced a famous tune from early Tang Dynasty called "Qin Wang Po Zhen Yue," which praised Emperor Taizong for charging into battle. Historical records suggest that "Qin Wang Po Zhen Yue" was derived from "The Song of Lanling King Entering the Battle Array." Once sung, "The Song of Lanling King Entering the Battle Array" became a popular song of the time, and it is easy to imagine that Gao Changgong's fame was at its peak. After Gao Wei ascended the throne, he once chatted with his cousin, Gao Canggong. Gao Wei asked, "Back then, you didn't care about me or the common soldiers deep in the enemy lines. If we lost, wouldn't you regret not coming in time?" The implication was that if the enemy killed him, it would be troublesome. Gao Changgong replied without hesitation, "Family matters are close to the heart; I didn't realize I had rushed in." Here, "family matters are close to the heart" means treating national affairs as if they were personal family matters. Clearly, King Lanling Gao Changgong regarded the country's wars as family affairs and served the Gao family, which made him feel very close to Gao Wei—like family. However, he did not fully understand the deeper meaning of Chinese political and cultural traditions: in traditional China, hierarchies are strict, with respect for superiors and inferiors, and the order of masters and servants cannot be crossed. In front of the emperor, one cannot communicate based on personality, kinship, or humanistic feelings, nor treat the emperor as an equal or family member. Such behavior might be acceptable among ordinary people, but Gao Changgong's closeness to the emperor as if he were a cousin was, in fact, a serious political mistake.
