The Tang Dynasty once set up a Persian governor's palace, which was an administrative organ established by the Tang Dynasty in present-day Zabole, Iran, and was subordinate to the Anxi Metropolitan Protectorate.
The Persian Empire was once so powerful that even during the Sassanid rule, its territory was far from comparable to what it is today. However, at the end of his reign, he met the rising Arabs. Persia also asked for help from the Tang, but Tang Taizong did not take care of it, and as a result, after supporting for a period of time, Persia was still wiped out by the Arabs.
Prince Belusi followed the Silk Road all the way to Datang. Originally, Tang Gaozong was also unwilling, but the Arabians went all the way to the east, and its power was unstoppable, so Tang Gaozong could not ignore it, and Tang simply escorted Balus to the west, and established the Persian Governor's Palace in the Persian City of Lingling (present-day Zabole, Iran), with Lu si as the Governor and under the jurisdiction of the Anxi Capital Protectorate.
But strictly speaking, this institution has existed for a short time, after all, it is very close to the Arabs, and it is impossible to tolerate such an institution under the eyes of the Arabs. At this time, The Arabs were in an upward period, not that the Tang Dynasty could not fight, but after all, the boats and cars were tired, and it was impossible to go to war for outsiders.
Of course, in any case, this Persian governor's palace has written a colorful chapter in Chinese history, telling the glory and prosperity of the Tang Dynasty in the past.
Hundreds of years later, the Ming Empire also set up an institution far away from the mainland, that is, the Old Port Propaganda and Consolation Division. Located in the city of Palembang on the indonesian island of Sumatra, it is the capital of the Indonesian province of South Sumatra.
Zhu Di launched the Battle of Jingnan to seize his nephew's throne, but his nephew disappeared. So Zhu Di began to go to the West in search of Emperor Jianwen.
At the same time, the Srivijaya kingdom in Southeast Asia was in decline, and Majapahit in the east was eyeing the tiger, and even landed in Sumatra at one point, and the Old Port area was already in chaos.
Just at this time, Zheng He came, three times five divided by two to get here done, the original Srivijaya Kingdom, it also became the Ming Dynasty's canonized old port Xuanwei Division. Shi Jinqing was still nominally king of the Sanqifo Kingdom, but officially the local administrator of the Ming Dynasty. The first envoy was Shi Jinqing.
The "Xuanwei Division" was the local administrative agency of the Ming Dynasty, generally located in the areas inhabited by ethnic minorities in the southwest, so some people believe that this place has become the territory of the Ming Dynasty. It is also said that the Old Port Xuanwei Division was a vassal of the Ming Dynasty, paid tribute to the Ming Dynasty, nominally under the jurisdiction of the Ming Dynasty, but in fact acted independently.
Some people even consider it from a strategic point of view, thinking that this can control the throat of the Malacca route. In fact, this is a bit too much to think about, imagining Zhu Di as a modern strategist.
Of course, it does not matter whether the Old Port Propaganda Department is daming's territory or not, but with Zheng He's voyage to the West, it spread Chinese civilization and enhanced China's friendly exchanges with Asian and African countries and economic and cultural exchanges.
