Nowadays, except for close relatives who cannot get married, any surname and any ethnic group can intermarry, but these 7 pairs of surnames in ancient mainland China, because of the blood feud between the ancestors, their descendants are forbidden to intermarry.
1. The surname Qin and the surname Yue
The surname Qin and the surname Yue are forbidden to intermarry, because of the grievances between Qin Hui and Yue Fei.
In 1127, the Jin army marched south, broke through the capital of the Great Song Dynasty (now Kaifeng, Henan), captured Song Huizong and Song Qinzong, and the Northern Song Dynasty perished. At that time, Qin Hui served as the imperial historian of the Northern Song Dynasty, and he, like Song Huizong, Song Qinzong and others, was captured by the Jin army and brought to the Jin State.

Zhao Gou, the ninth son of Emperor Huizong of the Song Dynasty, fled south and established the Southern Song Dynasty in the south. When the Jin people learned of this situation, they continued to go south, wanting to destroy the Southern Song Dynasty. At this time, a number of famous generals such as Yue Fei, Han Shizhong, Wu Jue, and Zhang Jun emerged in the Southern Song Dynasty, who led their troops to fight against the Jin army, repelled the Jin army, and kept the Southern Song Dynasty. After the Southern Song Dynasty stabilized, Qin Hui fled back from the Jin State and was reused by Zhao Gou.
In the process of fighting the Jin army, the combat effectiveness of the Southern Song army has also been significantly improved. After having the strength to fight against the Jin army, Yue Fei, Han Shizhong, Zhang Jun and other generals began the Northern Expedition, preparing to defeat the Jin army and recover their homeland. The Jin army was afraid that it would be defeated by the Song army and let the fruits of its decades of aggression come to naught, so it took the initiative to negotiate peace with the Southern Song Dynasty. Zhao Gou and Qin Hui both have "gold phobia" and are afraid of fighting with the Jin army, so they seize the opportunity to meet and make peace. In order not to affect the peace negotiations, Zhao Gou ordered Yue Fei, Han Shizhong and other generals to withdraw their troops. Yue Fei was unwilling to withdraw his troops, and Zhao Gou won 12 gold medals in a row to force Yue Fei to withdraw his troops. Yue Fei had to withdraw his troops, which ruined the ten years of Yue Jiajun's efforts.

After the peace negotiation, Yue Fei and other high-ranking military commanders with heavy troops became a threat to Zhao Gouxin, who connived at Qin Hui and his henchmen, collected evidence to frame Yue Fei, and killed Yue Fei for "trumped-up" treason. For this reason, the surnames Qin and Yue are at enmity, and their descendants cannot intermarry.
Second, the surname Wanyan and the surname Yue
The surname Wanyan is the surname of the people of Jinguo. Most of the Jin troops that Yue Fei fought against were surnamed Wanyan, so they were Yue Fei's sworn enemies on the battlefield.
One of the terms of peace between Jin Jun and the Southern Song Dynasty was that the Southern Song Dynasty wanted to kill Yue Fei. The Southern Song Dynasty did not agree, but afterwards Qin Hui fabricated evidence to kill Yue Fei, which made people very angry. Wanyan and Yue Fei were mortal enemies, so the descendants of the two surnames were forbidden to intermarry. After the Jin Kingdom was destroyed by the Mongols, most of the descendants of the Jin Kingdom with the surname Wanyan changed their surnames to Han surnames, and there are very few Wanyan surnames today.

3. The surname Lu and the surname Wu
Lü Mengzheng was the prime minister of the Northern Song Dynasty. Lü Mengzheng was generous and upright, honest and honest, and was a good official, but after he retired, an official surnamed Wu who had a dislike for him wrote to the emperor to frame Lü Mengzheng. In order to avoid the disaster, the descendants of the Lu family had to change their surnames to "Gao, Jiang, Lu, Ji" and other surnames, and fled everywhere. Therefore, the descendants of the Lu family hated the surname Wu very much and warned the descendants not to intermarry with the surname Wu.
Fourth, the surname Ji and the surname Ying
The founder of the Zhou Dynasty, King Wu of Zhou, Ji Fa, is surnamed Ji. The founder of the Qin Dynasty, Qin Shi Huang Yingzheng, is surnamed Ying. The state of Qin was once a vassal state of the Zhou Dynasty. After the Spring and Autumn Period and the Warring States Period, the Zhou royal family declined, and the vassal states gradually rose, especially the Qin State, which was reborn through the Shang Dynasty and became the strongest prince in the Warring States Period. After becoming strong, Qin's ambitions continued to swell, and he sent troops to destroy the Zhou royal family, and also annexed the Six Kingdoms, unified the world, and turned the world that originally belonged to the surname Ji into a world with the surname Win.

The hatred of the country made the descendants of the surname Ji hate the surname Win very much, and they did not allow their children and grandchildren to intermarry with the surname Winner. However, after the Qin Dynasty was destroyed by Liu Bang and Xiang Yu, many descendants of the winning surname changed to other surnames in order to avoid being hunted down by the enemy, and now there are almost no winning surnames.
Fifth, the surname of water and the surname of fire
The surname water is the descendant of the god of water, and the surname of fire is the descendant of the god of fire Zhurong. Gonggong, the god of water, and Zhurong, the god of fire, are both ancient mythological figures of the Chinese people, and the two have always been at odds, and they have fought and a big war broke out. In the process of fighting with the god of fire Zhurong, the god of water, he accidentally bumped into Buzhou Mountain, which broke a hole in the sky. For a time, the flood was rampant, the lives were devastated, and the world was in chaos. In order to save the living beings in the world, Nuwa refined colorful stones to make up for the sky, and only then did she quell the chaos. Since ancient times, fire and water are incompatible, so the surnames Shui and Fire are forbidden to intermarry.
Sixth, the surname Wu and the surname Pan
The surname Wu and the surname Pan are forbidden to intermarry, which originates from the story of Wu Dalang and Pan Jinlian in the Water Margin.

Pan Jinlian seduced Wu Song many times, but Wu Song was an upright person who didn't want to do anything to be sorry for his brother, so he flatly refused. Subsequently, Pan Jinlian was led by Wang Po and Ximen Qingguo to mingle together. After Wu Dalang found out, she and Ximenqing ruthlessly poisoned Ximenqing. This matter was widely spread in the mainland, and in order to avoid similar tragedies, the surnames Wu and Pan were forbidden to intermarry.
