Luzhen in The Legend of Luzhen is a female figure in the Northern Qi Dynasty and a beloved woman of King Gao Zhan. This TV series also describes Gao Zhan as a wise SHEN WOO. In fact, Gao Zhan in the history was also a bad king, not as good as what was written in the TV series, while Lu Zhen was the wet nurse of Gao Wei, the son of Gao Zhan, and Lu Zhen was a middle-aged woman when she entered the palace, so she had no affair with Gao Zhan.
Gauguin succeeded to the throne at the age of nine. Because Lu Zhen was his wet nurse, he trusted Lu Zhen very much. Because Gauguin was still very young when he ascended the throne, the power in the DPRK was in the hands of Hu Taihou, and Lu Zhen, as Gauguin's wet nurse, played an important role in the harem. Gauguin listened to Lu Zhen, and Lu Zhen consolidated his rights, so he let his dry daughter Muhuanghua marry Gauguin.
The more power Lu Zhen has, the more greedy she is. Slowly, she felt that Hu Taihou was blocking her sight, so she and Mu Huanghua conspired to frame Hu Taihou for adultery. Cushman & Wakefield was furious when he learned that his mother had committed adultery and imprisoned her directly. After Hu Taihou fell from power, the right of the harem was in the hands of Lu Zhen. Lu Zhen used her rights to get herself a position as a female official.
After Lu Zhen became an official, many villains were appointed as officials, which made the unstable Beiqi more corrupt. Later, the Northern Qi Dynasty was destroyed, and Lu Zhen committed suicide, so Lu Zhen in history and Gao Zhan in TV series were totally different. In history, Gao Zhan was completely a bad king who was addicted to beauty. We can only look at the TV series as a story, and there is no need to dig deep into the prototype in history.
