The great affairs of the kingdom are in the worship and the rong. The Seven Temples of Tianzi, the Five Temples of the Princes, the Three Temples of the Doctor, and the Shu people have none. This is the temple system, the Son of Heaven can only sacrifice seven generations of ancestors, and further up, it can only be "the ancestor of the ancestor is not my ancestor". According to the Jongmyo system, the ancestral temple is not a shrine, and if the Jongmyo temple is exhausted, it will be sacrificed. In other words, you can't enjoy the sacrifices of future generations on the throne of the temple, because if you don't have a shrine, the people behind you will have no place, so the ancestors who have been killed in front of you have to make room for the people behind you. The so-called Temple of Ancestry, in the words of Di Renjie when he persuaded Wu Zetian to make Li Xian, the king of Luling, the crown prince, could not eat blood, that is, could not enjoy the sacrifice offerings of live killing.
But there is a rule here, that is, the temple number has the ancestral temple is not the temple, the temple number of the zhiqi temple is the sect, or even the temple number is not. For example, in the Han Dynasty, some emperors did not have temple numbers, so the emperors of the Han Dynasty are now accustomed to being called Emperor Han of Han, because for example, Emperor Jing did not have a temple number, and if they were also called Tang Taizong Tang Xuanzong like the Tang Dynasty, then some emperors could not be consistent. Therefore, if you want to be kicked out of the temple in the next life, you must call the ancestor on the temple number.
This system has already been formed in the Zhou Dynasty, and there is no problem in implementing it, so it is recorded in the Zhou Li, and in the Han Dynasty, in fact, it is the end of the Western Han Dynasty, the period of Wang Mang Bingzheng, because the Han Dynasty from Gaozu Liu Bang to The Emperor of Sorrow has been the eighth dynasty, then there is a problem when the temple is there. Because it is retrospective upwards, if you want to go to the temple, you have to kick Emperor Wen out of the temple. In the Han Dynasty, Emperor Wen had a temple number, also Taizong, but Emperor Hui had no temple.
At that time, there was a lot of controversy, first kicked out a few ancestors, and soon encountered floods and droughts, all of which were natural disasters, and it was the time when the study of Wei Wei was popular, so soon some people thought that after kicking the ancestors out, the ancestors were angry, and the heavens surrendered their responsibilities, so they discussed it again. Before that, the problem that the temple was already full was still not solved, and after a while it was time to discuss the temple. After tossing and turning back and forth like this for a while, the people of the world felt that the number of Han Dynasty qi had been exhausted, and the ancestors were uneasy in the Taimiao Temple, so shouldn't it be finished?
For example, Cao Wei has three ancestors, Cao Cao is Emperor Taizuwu, Cao Pi is Emperor Shizuwen, and Cao Rui is Emperor Liezuming. Why is this problem? Generally a dynasty has an ancestor, the others are zong, after the Han Dynasty Wang Mang interrupted Liu Xiu rebuilt, such a big credit, but also the ancestor Guangwu Emperor, Cao Pi Cao Rui can have how much credit, also known as the ancestor? In fact, the reason is that Cao Rui is childless, and Cao Fang Cao Ishi Cao Huan is a foreign vassal who has entered the succession to the emperor. At that time, it was to ensure that Cao Pi Cao Rui was not kicked out, so the temple name was specially called Zu.
Of course, there are exceptions. For example, in the Northern Wei Dynasty, there are many ancestors, in addition to Taizu, there are also Xianzu, Shizu, Shizu is what we know of moved to the capital Luoyang Northern Wei Xiaowen Emperor, The Northern Wei establishment of the temple system was completed under the guidance of the family clan in North China at that time, they were all knowledgeable, why did they also engage in so many ancestors? Stay because the northern Wei dynasty started a relatively long process, all the way back to the Tuoba Li micro period, there must be a temple, and do not want to be qi, so bai out of the four ancestors, Emperor Xiaowen is the first person to promote Sinicization, with the Central Plains orthodoxy to pride themselves, of course, do not want to be left behind.
In fact, this problem was basically solved in the Eastern Han Dynasty, that is, although the Seven Temples had been used up, they could be flexible. This is actually very simple to do, that is, to put the tablet of the ancestor who has already done his best in the temple, but in the mezzanine, and then invite him to come out and accept the sacrifice together. In this way, the hard rules of the Seven Temples of Heavenly Sons were satisfied, and there was no need to kick the ancestors out of the Taimiao Temple, and basically did so later. The Tang Dynasty and the Song Dynasty did just that, no one raised any objections, and everyone was very satisfied.
When it was time for Jiajing, this question was raised again. Because Jiajing was succeeded to the throne in accordance with the principle of "brothers die and brothers die and be established in the order of Lun" when Emperor Wuzong was childless, Jiajing proposed to posthumously honor his father Xingxian As emperor, which was also a bill of great gifts. First of all, his mother also wanted to be called empress, then his father posthumously honored as the emperor, and then he proposed that since his father was already a righteous emperor, then of course he should enter the Temple of The Temple, and if he wanted to enter the Temple, he would have to drive away an ancestor from the Temple. Because the Temple of Qi is traced upwards, Taizu Zhu Yuanzhang cannot move, then there is only Emperor Taizong Zhu Di.
In fact, Jia Jing of course knew very well in his heart that Zhu Di's position would definitely not be able to move, and without Zhu Di's rebellion in the Battle of Jing, the imperial family would not be able to take their turn at all, how could they move? Therefore, Jiajing actually deliberately gave the minister a problem and let the minister guess the answer he wanted. The chancellor was not stupid, and the final compromise plan was that Zhu Di's temple name was changed from Taizong to Chengzu, so that it would not be moved for all generations, and there was no need to occupy the quota, and Jiajing's father, Xingxian Wang, could also enter the Taimiao Temple in a dignified manner. This is a step further than the Han Dynasty's Dingtao Andui and Pu deliberations.
In fact, from Zhu Di himself, he has actually been imitating Tang Taizong, so he is more willing to ask for the temple name of Taizong, so that it seems low-key and gorgeous, and can hide the fact of rebellion that he has always wanted to hide. After he ascended the throne, he not only abolished Jianwen's era name, but also canceled the imperial title that Jianwen gave to his father Zhu Biao, in order to directly receive the imperial lineage from Taizu Zhu Yuanzhang to her. The temple name of Chengzu seems to be taller than Emperor Taizong, which is actually equivalent to acknowledging the fact of rebellion and violating Zhu Di's original intention. But Jiajing himself fulfilled his wish to tuck his father into the Taimiao Temple.
