We all know that it is the son of the queen. But if the empress dies or is deposed, and the emperor creates a new empress, then the son of the new empress becomes a concubine. That is to say, the concubine is not immutable, let alone lifelong, once his motherhood changes, then his status will also change, of course, everything is not absolute, there are exceptions.
The first empress of the founding emperor of the Eastern Han Dynasty, Liu Xiu, was named Guo Shengtong, and her son Liu Qi was originally a prince and naturally a concubine. However, Emperor Guangwu eventually deposed Empress Guo and replaced her with Empress Yin Lihua. Then Yin Lihua's son must be a concubine. Although the status of the crown prince did not change with the change of his mother's status, he became a concubine from a concubine.
It is not that Shuzi must not be a prince, and he has not abolished the crown since ancient times, but the humble and intelligent Liu Qi knew that since his mother had abolished the middle palace, then it was not in line with etiquette for him to live as a concubine, so he asked the emperor to abolish his position as crown prince, and Emperor Guangwu also agreed.
It can be seen that after the empress was deposed, his son's status would also change.
For such a case, Liu Qi is smart. Emperor Guangwu had expressed the meaning that his position as crown prince was stable, but for Liu Qi, his heart was a mistake, after all, the royal family had no father and son, and since his mother was no longer an empress, could the new empress accommodate herself? I am afraid that every new queen wants her son to be her successor, unless she has no son.
In ancient times, it was the inheritance system of the eldest son, which was customized, not to say that it was changed. Therefore, for his own safety, he gave up the position of prince, which was still wise.
Besides, the emperor actually broke the primogeniture system in many cases, and many times it depends on the emperor's preferences, so in this case, the emperor must have a special love for the son of the new empress.
Some people also think that the son of the deposed queen is still a concubine, but in fact, if we think about it carefully, although there are such examples, it is not known whether he is welcomed or not.
So even if the son of the deposed queen is still a concubine, then his position will be threatened, there is no real succession, no one dares to guarantee anything, everything is still unknown.
To put it bluntly, although the concubine comes with her own blessing, many times the risk is also very large, and the confused are involved in the vicious fight of the royal family, and they can't hide from it.
