Hearing "Persia", everyone will first think of "Persian beauty", hearing Iran, everyone may not think of beauty, but Persia is the ancient name of Iran, Persia arose in the southwest of the Iranian plateau, from 600 BC, the Greeks called this area "Persia", until 1935, reza Khan, who established the Pahlavi Dynasty, changed the name of the country to Iran, and never used the name "Persia".

During the Tang Dynasty, China's society was open, there were many contacts with foreign countries, and there were also inextricable relations between Persia and the Tang Dynasty, and during the Tang Taizong period, the last king of the Persian Sassanid Dynasty asked the Tang Dynasty for assistance, but Tang Taizong refused on the grounds that the road was far away.
Later, before the fall of the Sassanid Dynasty, the Persian prince Belus traveled thousands of miles to Chang'an in China to ask the Tang Emperor for help, but in 661, Emperor Gaozong of Tang established the Persian Governor's Palace, and Belus became the local Governor, that is, the tang Dynasty's courtiers, and many Persian royals followed Belus to Chang'an, so Chang'an built the Persian Hu Temple.
In 1955, Xi'an discovered the tomb of Su Yu and Ma Shi of the Tang Dynasty Zuo Shen Zhi Army, and from the excavated cultural relics and historical records, archaeologists learned that this Tang Dynasty general was still a Persian king, and the inscription on the epitaph also had Chinese and Persian Pahlavi scripts.
However, after pahlavi translated into Chinese, there was a big difference from the Chinese character inscription, and the face of the expert also changed immediately, the Chinese character inscription is: "Zuo Shen Ce Army Scattered Soldiers and Horses Made Su forgive his wife Ma Shi, he was born, at the age of 26, died in the fifteenth year of Xiantong, the fifteenth year of The Year of Xiantong, the twenty-eighth day of the Xin Dynasty, the twenty-eighth day of The Death of Ding Weishen. ”
Pahlavite translates Chinese as follows: "The tomb of this deceased of the royal family, the cavalry of the Left God's Army, Su Yu Ma Xishi, died in the month of the founding of the 5th month of December of the fifteenth year of the 15th year of the xiantong, the 26th year of the reign of the victorious monarch, and may return to the side of the supreme god Ahula Mazda, and live eternally in the most beautiful heaven and rest in peace." ”
One is said to be the wife of Su Yu, the other is said to be the daughter of Su Yu, the amount of information is not generally large, and this has to talk about the ancient Persian Empire's state religion Zoroastrianism, which China calls "xiān" religion, Islam is called "Zoroastrianism", and the Persian Empire's state religion classic "Avista" believes in the marriage of close relatives, especially blood relatives, in order to ensure blood lineage.
But our country since ancient honor, the act belongs to one of the "ten evils", that is, the precursor of the crime of "civil unrest", will be sentenced to "animal behavior (ancient criminal law name)", punished by death, Su Yu is in the Tang Dynasty, certainly did not dare to marry his daughter, for this reason concealed the Tang Dynasty, but the Persian insiders are still clear, so that the Chinese character inscription records that Su Yu's wife, Persian is Su Yu's daughter, but Su Yu did not expect that after thousands of years, his secret was revealed to the world.
