The reign name doesn’t matter, the emperor’s name is taboo, and the country’s name is even less taboo. The era name is used by people to record the year, just like the current "X year", the almanac at that time said "X year of Hongwu" and "X year of Yongle". In fact, Zhu Yuanzhang's name is not taboo. As for the taboo of the country's name, there is no precedent in history. How could there be such a taboo in the Ming Dynasty? As Brother Qiufeng said, Wang Shouren, a great Confucian scholar of Neo-Confucianism, had the courtesy name Yangming.
Ha, another point is that the seniority of the emperors of the Ming Dynasty is not taboo.
