Then the king of Ceylon: Alie Kunaer, after inviting the Ming Si Rite Eunuch Zheng He, after waiting for the shore to arrive at the palace, he stretched out his hand to ask the Ming Rite Eunuch for the treasure, and also asked the Ming army fleet waiting for the shore for money, but the Ming Rite Eunuch: Zheng He is a messenger to stabilize the frontier, not a mediocre person who scatters money everywhere, he must not be able to agree to such an unreasonable request.

So he sent troops to rob the Ming army, relying on the local army and the Ming Si Rite Eunuch Soldier is few, when encountering this situation, the Ming Rite Eunuch did not mess up, but saw that the king sent an army to rob at this time, then the palace must be empty, so he led 2,000 people to raid the royal city and capture the Ceylon king's family, and the Ceylon army that was robbing immediately came back after getting the news.

Taking advantage of the chaotic return of the Ming army, the Ming army launched an offensive, and the Ceylon army also captured the king of Ceylon and returned to the Ming Dynasty to present it to Ming Taizong, and Ming Taizong used the prestige of the Great Ming Dynasty to exempt the king of Ceylon from capital punishment and return to China.

In 1408 A.D., the Tatar Taishi of the Northern Yuan Dynasty of the Asut Department: Arutai, killed the leader of the Qierji tribe, Wulei Timur Khan: Ugqi Guilichi, and claimed that he wanted to learn from the Three Kingdoms period of the Shu Han State Prime Minister: Zhuge Liang (Kong Ming) to restore the Northern Yuan Dynasty, and also welcomed the Northern Yuan descendant Tu Khan: Erjin Benyasuri, who was enthroned as the Northern Yuan Tatar Khan.

Later, the Northern Yuan Tatar Taishi: Arutai, and the leader of the Oirats in Moxi: Juros Mahamu, who was in the west of the Moxi, were at war for many years, and the leader of the Eirat was forced to send envoys to the Ming Empire.

Ming Taizong planned to salute first and then send Ming Daning to command the envoys: Jin Tabu and Ming Like gave Guo Ji in the matter: Guo Ji, the two went to the Tatar Khanate with gifts to appease, but they were unexpectedly detained by the Tatar Khan of the Northern Yuan Dynasty and the envoys seized the gifts.

After this incident was reported to the Imperial City of Tianfu, Ming Taizong was furious, thinking that the barbarians were rude and the border trouble was not trivial, and he decided to send troops to crusade, he ordered Ming Qi Guogong: Qiu Fu, wearing the seal of the general of the conquest, and serving as the "Pinglu General Army" Ming Wucheng Marquis: Wang Cong, Ming Tongan Hou: Huo Zhen, for the left and right deputy generals, Ming Jing Anhou: Wang Zhong, Ming An Pinghou: Li Yuan for the left and right generals, led 100,000 cavalry.

Hearing that the Ming army was attacking the Tatar Khan of the Northern Yuan Dynasty and migrated directly from Beishu Bali to the Yuqu River Valley, the Ming Qi Duke and the general army of Pingyu: Qiu Fu, personally led a thousand iron cavalry to the south of the Yuqu River, and encountered the cavalry assault of the Tatar Khanate.

However, the Ming army defeated it with a fire team and an artillery battalion, captured a group of surrendered Tatar Khanate cavalry, only to learn that the Tatar Khan of the Northern Yuan Dynasty was also nearby, and the Ming Qi Guogong, who was carried away by the victory, did not care about the consequences at all, and directly ordered the whole army to pursue, but was besieged by the Tatar Khanate army, and was defeated, and all 100,000 Ming troops were killed!

In April 1409, the seventh year of Yongle in the Ming Dynasty, Taizong of the Ming Dynasty was officially promoted to the "Commander of the Nuer Gandu" and was named the commander of the Dongning Wei of the Ming Dynasty: Kang Wang, the commander of the Tongzhi for the Nuer Gandu, and the 30,000 Wei Thousand Households of the Ming Dynasty: Wang Zhaozhou, the commander of the Nuer Gandu, and the Ming Kemuwei Zhenfu: Tong Da Laha, the commander of the Nuer Gandu, the Ming Nuer Gandu Command of the Envoy of the Ming Nuer Gandu: Liu Xing, the commander of the Nuer Gandu of the Envoy, and added some guards, a total of 384 guards, 24 guards of a thousand households.

The capital is located on the east bank of the Heilongjiang River, and has jurisdiction over the area from the Onen River in the west, to Kuwu Island in the northeast, to the Wudi River in the north, and to the Shogunate Sea in the south, so that the four Jurchen tribes of Haixi, the eight Jurchen tribes of Jianzhou, and the chieftains of the Savage Jurchen are all attached to the Ming Dynasty, completing the unification of the Ming Empire in the northeast region.

After that, the leader of Warat: Gulos Mahamu, who was named the king of Shunning County by the Ming court, Nairahu Taiping, was named the king of Xianyi County, and Horos Polo, was named the king of Anle County, and since then the north has become a vassal state of the Ming Dynasty Among the three kings, the king of Shunning County of the Ming Dynasty: Horos Mahamu, the strongest force formed an alliance for the hegemony of the Khan, and also fought against the Northern Yuan Tatars.

The Ming Empire called the "Oirat Alliance Region" Warat, and since then the north has been officially divided into three parts, namely "Warat, Tatar, and Ignorance of the Teeth", and the Ming Dynasty took advantage of the contradictions between the two sides to first seal the three leaders of Warat as the county king, and let them fight each other.

In October, Ming Taizong dispatched the Ming Si Rite Eunuch and Envoy for the third time: Zheng He, Ming Si Eunuch and Deputy Envoy: Wang Jinghong, Ming Si Rite Eunuch: Hou Xian, led more than 27,000 officers and soldiers to drive 48 sea ships, set sail from Liujiagang, Taicang Lake Patrol Division, and passed through Champa State, Bintong Long, Zhenla State, Siam State, False Martin Island, Jiao Lang Mountain, Java State, Chonggaro, Jiri Suldi, Guli Country, Manraka Country, Pahang Kingdom, Dongxizhu, Longya Jiamiao, Danyang Kingdom, Sumatra Kingdom, Huamian Country, Ambergris Island, Cuilan Island, Aru Kingdom, Ceylon, Little Gülan, Kochi, Punggara, Bulawa, Zhubu, Mugudushu, Sulu, and other countries.

Among them, Manraka was still a dependency of Siam at that time, and the eunuch and envoy of the Ming Dynasty were enshrined by Emperor Taizong of the Ming Dynasty, giving the local chieftain a double silver seal with a crown and robe, and a stele to let the region establish the Manraka State alone, and Siam did not dare to invade the Manraka State since then, so the King of Manraka was very grateful for the help of the Ming Empire and paid tribute almost every year.

On the first day of February 1410 in the eighth year of Yongle in the Ming Dynasty, Taizong of the Ming Dynasty issued an edict to the Northern Yuan Tatar Finisher Tu Khan: Ben Ya lost his life, and submitted to the Ming Empire and he did not obey!

So Ming Taizong was furious in order to solve the northern border troubles and directly prepare for the imperial expedition, and immediately appointed the emperor's eldest grandson: Zhu Zhanji, who stayed in Beijing, and was in charge of the ministry of the Ming household: Xia Yuanji, and then issued an edict to the world on the northern expedition, and selected the scholars of the Ming Hanlin Academy: Hu Guang, the Ming Hanlin Academy's attendant: Yang Rong, and the Ming Hanlin Academy's close attendant: Jin Youzi, who was the companion of Hu.

Ming Jingyuan Marquis: Wang You, for the squadron general, Ming Anyuan Marquis: Liu Sheng, as the deputy general, Ming Ning Yuanhou: He Fu, Ming Wu Anhou: Zheng Heng, for the left and right sentinels, Ming Ning Yang Marquis: Chen Mao, Ming Guang Enbo: Liu Cai, responsible for the right and left two pinch attacks, Ming Zhong Military Governor's Mansion Right Governor: Liu Rong, as a guerrilla general as a vanguard, and ordered Ming Xixing Capital Commander: Xue Lu, Ming Shandong Commander Envoy: Ji Jie, for the left and right hussar generals, Ming Ping Mountain Guard Commander: Hou Yong, Ming Changshan Right Guard Commander: Chen Zhi, for Shenji General, The commander of the southern capital of the Ming Dynasty: Jin Yu, the general of Yingyang, the commander of the capital of the Ming Dynasty and the commander of the capital of the Ming Dynasty, Li Wen, the general of the chariot cavalry, the sub-governor of his subordinates who were not subordinate to the governor's office of the five armies, a total of 500,000 troops marched north from the inner city of Gyeonggi out of Deseungmen.

On the 2nd day of March, the Ming army from all walks of life gathered in Suidewei to carry out a military parade and swearing-in ceremony.

On the first day of May, the army arrived at the Yuqu River, Ming Taizong got off the car and drove and personally gave this place the name of "Drinking Horse River", and then it was attacked by the Wara Iron Cavalry lurking in Pingmo Town from the plains, shooting an arrow, leaving four horses and retreating, and there was also a letter of persuasion written on it that was directly torn up by Ming Taizong.

On May 17th, he learned that the Warat cavalry was not far from this, so he ordered the army to cross the Yinma River, and the battle of the Northern Yuan Dynasty Completer Tuhan who sat in the Yatent severely injured the Warat Iron Cavalry to force them to flee, and Ming Taizong led the light cavalry to pursue to the Troubled River to fight again, and defeated the Warat Infantry Cavalry Army, resulting in the Northern Yuan Dynasty Completer Tuhan only seven horsemen to escape, and the Ming army was still in pursuit.

On May 20, Ming Taizong ordered the division of troops to pursue the Northern Yuan Tatar Taishi, and the Northern Yuan Tatar Taishi was familiar with the terrain and occupied a favorable area, so he fought and retreated, so that the Ming army was in a passive and helpless form, and could only send people to summon and surrender, but the Northern Yuan Tatar Taishi hesitated.

The two sides held each other for many days, and although the Ming army had small victories from time to time, they were unable to sustain the hunger and thirst of the soldiers due to the hot weather, so they ordered the division in June and returned to Shuntianfu on July 17.

On July 21, the leader of the Hui tribe: A Ra Ma Ya, beheaded Liu Bingqian, the commander of the Ming and Shaanxi provinces, occupied Suzhou Wei and began to rebel, and asked the Chijin Mongols to guard the Qianhu Office, Andingwei, Handongwei, Qu Xianwei, Aduanwei, and Shazhouwei as reinforcements.

However, the Chijin Mongol Guardian Qianhu remembered that the Ming Emperor did not intend to join the rebels, so he secretly asked Zhuwei to nominally agree to join the rebellion, but in fact, while playing the imperial court, he led his subordinates to capture the Aramaya and hand it over to the imperial court.

This incident made Ming Taizong very happy, and he also changed the Chijin Mongol Guard Thousand Households to the "Chijin Mongol Guard" award: Talini, the commander of the Chijin Mongol Guard, and the three of his subordinates were also sealed, so that the rebels fought alone and were besieged by the Ming Shazhou Wei Qianhu: Judy, and led the army to besiege and finally pacified.
