The cabinet team composed of "Sanyang" in Ming Dynasty was called the strongest cabinet in Ming Dynasty. Their contribution lies in: assisting Ming Renzong to succeed to the throne and realizing Ming Xuanzong's ambition. Under their rule, the prosperity of the Ming Dynasty continued, and the rule of these two emperors became a famous rule in history: Ren Xuanzong's rule.

First of all, let me talk about the succession of Emperor Renzong of Ming Dynasty. It is the efforts of "Sanyang" that enabled Zhu Gaochi to inherit the unification smoothly and avoid the infighting within the dynasty again. At that time, Injong was the eldest son of Judy, the founding emperor of the Ming Dynasty. In the twenty-eighth year of Hongwu, he was named the Prince of Yan. It seems that he will succeed the Prince of Yan, but Judy obviously doesn't like this son: First, Zhu Gaochi is obese and inconvenient to move, and sometimes he needs help to get in and out; Secondly, because I am a Confucian student, I have a generous and kind personality, which is a little far from Judy's cruel personality.

At that time, Zhu was the second child and was deeply loved. He fought bravely in a difficult situation. He also tried his best to fight and got Judy's hint that "the prince is ill, so you should encourage him". Every father likes to be like his son. When Judy won the world and planned to set up a bank, he also hesitated, mainly because the ministers of the DPRK were divided into two factions. Most civil servants support the establishment of Zhu Gaochi, and they adhere to the motto of "standing for a long time and not standing young"; The military commander Zhu supported his comrades to stay in Jingnan.

Although Zhu Gaochi was chosen as the prince after careful consideration, the struggle between the two sides continued until Judy's death.

During this period, the Zhu side gained the upper hand several times. The most dangerous one was that the prince directly became centralized, and all the main officials of the East Palace were investigated, including Yang Pu, one of the "Three Yang". This gentleman was arrested in the Royal Guards' "Imperial Prison" and stayed there for ten years! In such a dangerous situation, "Sanyang" always supported the prince and tried to stabilize his position. Through their efforts, the prince was pulled back from the cliff.

Finally, Judy died in Yumuchuan during the fifth Northern Expedition. In order to prevent Zhu's rebellion, he personally went back to Beijing to mourn the Prince and made preparations for the Prince's accession to the throne with other personnel, thus ensuring the smooth transfer of power.

Secondly, "Sanyang" assisted Xuanzong in realizing his ambition. After Xuanzong succeeded to the throne, he carried out his father's principles and policies, resumed production and recuperated, and reduced the burden on farmers by not apportioning. During his reign, all the affairs in the mainland and the frontier were properly handled under the governance of "Sanyang". Of course, Xuanzong also gave the cabinet a lot of power, such as "drafting votes." This power was first examined by the cabinet on the various memorials received, and then submitted to the emperor.

With their joint efforts, the national strength of the Ming Dynasty was flourishing. In A.D. 1430, Xuanzong once again sent Zheng He to the Western Ocean to declare the majesty of Daming. Zheng He's voyage to the Western Seas needs the support of national strength, which in itself is a loss-making business. For Xuanzong, who cherishes the people's strength, it shows that the national strength of the dynasty is enough to support the consumption of the ocean.
