What was the title of the imperial edict before the Ming Dynasty?

In ancient China, imperial edicts were not all called imperial edicts. According to the book "Imperial edicts of China", imperial edicts were called "destiny", "decree" and "government" during the Spring and Autumn Period and the Warring States Period, and it was not until the Song Dynasty that imperial edicts were generally called "imperial edicts". The opening words of the imperial edict are not all "goods are delivered in heaven, and the emperor summoned them to say", but each dynasty has its own differences: in the Tang Dynasty, the opening words of the imperial edict were mostly "under the door", because the imperial edict at that time was generally issued by the province under the door. For example, the beginning of the imperial edict of Crown Prince Su's Supervision of the Country is: "The door is the foundation of the world ..." It is also useful for "I" in the Wei, Jin and Southern and Northern Dynasties, and the word "obey" is often used at the beginning of the imperial edict to clarify the "orthodoxy" of the son of heaven. The highest god of the Mongols is immortal heaven, so the first sentence of the imperial edict of the Yuan Dynasty is always "immortal heaven is powerful, blessed with great protection, imperial edict ..." It was the first sentence of Zhu Yuanzhang, the first emperor of the Ming Dynasty, who used "to serve heaven as an imperial edict". In other words, the word "Fengtian carries the imperial edict of the emperor" appeared in the imperial edict and began in the Ming Dynasty.

According to Shen Defu's Wanli Wild Collection in the Ming Dynasty, after Zhu Yuanzhang made Nanjing his capital, he renamed Nanjing Yingtianfu and named the largest golden palace in the palace as Fengtian Hall. In order to show the legitimacy of his "son of heaven", he called himself "the ancestor of Fengtian" and carved the word "the ancestor of Fengtian" on the jade GUI he held. Later, in order to find the "theoretical basis" and strong evidence of "Fengtian Shipping", Zhu Yuanzhang himself wrote an article "Dream of Imperial System", which vividly described his dream of the Heavenly Palace, saw the "Three Clean Ways of Taoism" and was given real costumes and swords by Taoist Ziyi. Since then, Zhu Yuanzhang began to call himself "Fengtian carries the imperial edict", and when he released the imperial edict again, he used these eight words as "prologue". Later generations handed it down, forming a fixed form of imperial edict prologue.

Moreover, it is worth mentioning that the correct sentence pattern of "Fengtian carries the imperial edict" should be "Fengtian carries the imperial edict", rather than the pronunciation of "Fengtian carries the imperial edict" in current film and television works.
