Rest is an empire, the Parthian empire, the ancient slave kingdom of Iran. Founded 247 years ago, Arsasi was the founding monarch, and Pattaya is roughly equivalent to Khorasan region in Iran today. It was a province during the Persian Empire and Seleucid Dynasty. The name Parthia comes from the name of the Persian nomadic Palne tribe, and the Parthians belong to a branch of the White Xiongnu. The Han Dynasty took the Chinese transliteration "Rest in Peace" as its name. At the beginning of the 3rd century BC, the Palne branch of the Nomadic Sea Tribe Alliance migrated from the present Syr Darya River valley to Pattaya, where it merged with the local residents. In 247 BC, Assassinus, the leader of Palne, killed the governor of Seleucid dynasty and established Assassinus dynasty with Nisa (now Ashgabat, Turkmenistan) as its capital. The Han Dynasty was named after the Chinese transliteration of Alsace Dynasty "Rest", which was called Rest, while the western historians called it Parthia. In 226 AD, it was replaced by the Sassanian dynasty in Persia. It reaches the Caspian Sea in the north, the Persian Gulf in the south, Daxia and ancient India in the east, and the Euphrates River in the west, that is, all the territories of Iran, Iraq and Armenia, Turkey, Georgia, Azerbaijan, Turkmenistan, Tajikistan and Afghanistan. Dash, the collective name of Arab dynasties in Tang and Song Dynasties, is the transliteration of Tazi or Taziks in ancient Persian, and Ye Yuan in Hanzhong is called the tribe of the former Kuli State (now Iran). Since the middle of the 7th century, people of all ethnic groups in Arabia have been collectively referred to as "big food", "big food" and "big love" in the Song Dynasty literature since the middle of the 10 century. Some people in history books also call it Tashi, Tazi and Tazi.
With the eastward expansion of the Arab caliphate in the 7th century, Persian speakers in Iran and Central Asia gradually converted to Islam. Therefore, all Persian-speaking Muslims in China are regarded as Arabs, and some ethnic groups around them are called cannibals, so the meaning of cannibals has expanded from the late Southern and Northern Dynasties to the early Northern Song Dynasty. Sassanian Dynasty (226 -650) was the ruling dynasty of Persia from the 3rd century to the 7th century. It is also the first unification of Persia since Achaemenid Empire, and it is considered as the second Persian Empire. At that time, Sassanian dynasty, together with the Indian Guishuang dynasty in Central Asia, the Eastern Han dynasty in East Asia and the Roman Empire in Europe, was also called the overlord of the four countries of Europe and Asia. In its heyday, Sassanian dynasty repeatedly threatened the neighboring Guishuang dynasty and the Eastern Roman Empire. Later, due to the assassination of two successive kings of the dynasty, the imperial center collapsed, and the son of the last king, Isiah III, fled to the Eastern Tang Dynasty and served as general Wei. At that time, the Tang Dynasty was ruled by Tang Gaozong.
