In fact, robbing his son's wife is not a patent of Tang Xuanzong, but a precedent. During the Spring and Autumn Period, King Chu Ping abandoned his illness and robbed his wife. When I was young, I abandoned my illness and ignored etiquette. Before he became king, he worked as a doctor in Cai, Chu. He dated a woman in Cai Guo and gave birth to a son without getting married. After she abandoned her illness as the king of Chu, she snatched this daughter from the unmarried Cai and made her son a prince.
When the Prince of Yan was fifteen, King Chu Ping hired Meng Ying, the sister of the King of Qin, as his wife, and sent Shao Shi, the Prince of Yan, to see his relatives. Fei Wuji went to Qin and found that she was actually a natural beauty. As soon as Fei Wuji returned to Chu, he told the good news to King Chu Ping and suggested that King Chu Ping take Meng Ying as his own. Wang Ping readily accepted this shameless suggestion. So Fei Wuji told the guards of Qin that according to the custom of Chu, the bride must visit her in-laws in the palace before a formal wedding can be held. In this way, Meng Ying was sent to the palace, and became the bag of King Chu Ping. Later, King Chu Ping married a young girl to Prince Jian and named her Meng Bi. A year later, Meng Yisheng gave birth to his son, and the scandal began to leak.
However, in the history of China, King Chu Ping was not the first emperor to take away his son and wife. Wei, who was 200 years earlier than him, was "the first person to eat crabs". Wei promiscuous when he was young. He had an affair with his father's little wife and gave birth to a son named Wei. Because Wei was the result of incest, he had to be fostered among the people when he was a child. After Wei became king, his affair with Wei became public, and Wei was also named Prince. When Wei was sixteen, he asked his eldest daughter, Xuan Jiang, to be his wife. The messenger sent by Qi State to find relatives and friends came back and said that Xuan Jiang was beautiful. Hearing this, Gong Wei was open-minded and gave a bad idea. He ordered the construction of luxurious palaces on both sides of Qihe River and named them Xintai. Then let Wei go to Song. Go ahead, Aunt Wei. Wei will send someone here to meet his relatives and marry Xuan directly to the new station as a concubine. After Wei came back from Song Dynasty, he asked Wei to see Xuan Jiang in concubines' week. Dad cooked uncooked rice into mature rice, so Wei had to accept his fate.
These emperors swept the world and did whatever they wanted. However, in the eyes of the world, it is always a joke that Lao Zi robbed his son's wife.
