First of all, in history, Dou E Yuan was not a spy planted by Lv Zhi around Liu Heng, but an ordinary beauty. When she first arrived in Daiguo, she was really loved, but that was only because of her beauty. When she was old and weak, Liu Heng left her behind and favored other beautiful women. Moreover, the reason why Dou was named the queen was also at the proposal of the DPRK minister and the thin queen mother, not as mentioned in the TV series.
Speaking of political achievements, Dou is not very famous in history, and he can't help in major events in North Korea. He is not like Dou's wife in TV series in life and politics. It can be said that Dou E's injustice did not really enter the center of power, but Lv Zhi was different. After the death of Emperor Gaozu Liu Bang, Liu Yuxin was sickly and indecisive, while the Queen Mother Lv Zhi was in charge of state affairs.
Although Lv Zhi's criticism is not good in history, she is still decisive in court and state affairs. People often compare her with Wu Zetian in history, which shows that her ability is still recognized. And judging from the situation at that time, Dou E's grievance has neither strength nor ability, so no matter from which aspect, Dou E's grievance can't learn from Lv Zhi.
