Ming Yongle Third year (1405), Ming Chengzu Zhu Di ordered Zheng He urged the world's largest fleet at that time to start a vigorous voyage to the West. Zheng He's fleet consisted of 300 warships (including 66 huge sea ships), more than 27,000 sailors, and even equipped with thousands of war horses. It is no exaggeration to say that this was the unquestionable "invincible fleet" in the world at that time. Zheng He's fleet set out from Zhangjiagang near Nanjing and traveled through the East China Sea and the South China Sea . Along the way, he visited many countries on the Indochina Peninsula and Java Island and Sumatra Island . When the countries saw the huge Ming navy, they were all impressed from the bottom of their hearts, and they paid tribute to the Ming Dynasty. Zheng He's voyage was very successful. Therefore, Zheng He prepared to continue traveling west across the Malacca Strait to the Indian Ocean to open up the connection between the Ming Dynasty and the countries along the Indian Ocean.
Just as Zheng He's fleet crossed the Strait of Malacca, at that time, the Chen Zuyi Pirate Group occupied the old port, the most important port on the Strait of Malacca (now Palembang, Indonesia). Chen Zuyi was originally a Ming Dynasty . Because he committed a lawsuit in Ming and fled to Malacca, he gathered a group of people to do the pirates' livelihood. With his business ability, he developed the team to more than 5,000 people. He was one of the top leaders in the Strait of Malacca. Because of the golden waterway of the Strait of Malacca, there were many ships passing by, so Chen Zuyi made a fortune accordingly. At that time, the Ming Dynasty started exploring overseas careers for the first time, and the importance of the overseas military base was even more prominent. Therefore, Zheng He tried to appease Chen Zuyi with national justice, hoping to build an overseas base for the Ming Dynasty in Chen Zuyi's old port.
Faced with the olive branch stolen by Zheng He, Chen Zuyi was not grateful at all, and even planned to attack Zheng He's fleet and seize the property of the Ming Dynasty. The truth is backfiring. Chen Zuyi is used to becoming king in Malacca, and he really doesn't know how much he is. Chen Zuyi's attack gave Zheng He an excellent reason to wipe out him. In front of the regular navy of the Ming Dynasty, Chen Zuyi's pirate group was simply vulnerable. Zheng He mercilessly wiped out this pirate force in the Strait of Malacca for many years and captured Chen Zuyi alive. Then he took him to Nanjing to kill him to summon the Ming Dynasty to inviolate.
After the war, Zheng He, in view of the important strategic position of the old port, sent some Ming troops to stay. When he returned to Nanjing to report his duties to Zhu Di, he specifically reported the details of the old port. Zhu Di then set up the old port 1 Old Port Xuanwei Department in the old port, with local overseas Chinese Shi Jinqing as the first Xuanwei envoy. Since then, the old port has become the most important strategic base of the Ming Dynasty in Southeast Asia and the "Pearl Harbor" of the Ming Navy in Southeast Asia. During Zheng He's voyage to the West, the Ming fleet had to supplement supplies for the old port, and it was also a rest stop during the ocean voyage. The Ming Dynasty's troops in the old port also became the best way to deter Southeast Asia those who were malicious about the Ming Dynasty. It can be said that having the old port is equivalent to pushing the Ming Dynasty's maritime border from the South China Sea to Malacca, which is so magnificent.
Ming Hande 5th year (1430 AD), Zhu Di's grandson Ming Xuanzong Zhu Zhanji launched the last voyage to the West in the Ming Dynasty. It was also during this long voyage that Zheng He, the best navigator of the Ming Dynasty, passed away on the way, and the Ming Dynasty's voyage to the West became a masterpiece since then. In the ninth year of Xuande (1434), Zheng He's comrade-in-arms Wang Jinghong led the Ming fleet to envoy Sumatra and other Southeast Asian countries to conduct routine visits. The fleet stayed for a short rest in the old port, and then returned to the country. Since then, the Ming Navy has never returned to the old port.
In 1440 AD, the Xuanwei Department of the Old Port was attacked by the surrounding powerful country "Manzhe Boyi". At that time, the Xuanwei Department of the Old Port was unable to resist at all and could only choose to surrender. The Ming Navy fell in the most important base in Southeast Asia. Because the distance was long, it was already a year later when the news reached the capital of the Ming capital. At that time, the Ming court had changed its foreign policy. In addition, the rise of the northern grasslands became a confidant of the Ming Dynasty, which made the Ming Dynasty no time to take care of the distant Malacca.
180 in 1620, the Dutch East India Company occupied the old port and used it as an important base for invading Asia. Four years later, the Dutch invaded Taiwan. It was not until 1662 that the national hero Zheng Chenggong expelled the Dutch from Taiwan through a bloody battle and recovered the treasure island of Taiwan that had been occupied for 38 years.
