What is the name of the palace in Luoyang after Wu Zetian proclaimed himself emperor?

There were mainly three palaces in Chang 'an City in Tang Dynasty, which were the palaces in Luoyang after Wu Zetian proclaimed himself emperor, namely Taiji Palace, Daming Palace and Xingqing Palace, which were collectively called "Inner Three Palaces". Among them, "Ouchi" is the Taiji Palace in Miyagi, the residence and meeting place of emperors in Sui Dynasty and early Tang Dynasty. Tai Chi Palace is1285m wide from east to west and1492m long from north to south, with an area of about1.92km2.. The palace is divided into three areas from south to north: the former dynasty, the later dynasty bedroom and the back garden. The main hall of the former dynasty was Taiji Hall (called Daxing Hall in Sui Dynasty), surrounded by huge palaces surrounded by cloisters, with official offices on the east and west sides. The main hall of the back bedroom is Liang Yi Hall, surrounded by Wanchun Hall, Qian Qiu Hall, Ganlu Hall, Shenlong Hall and Anren Hall. The garden is located in the last part of the palace, with pavilions and ponds. There is Xuanwu Gate on the palace wall in the north, where the famous "Xuanwu Gate Change" took place. Because the Taiji Palace was built by Emperor Wendi of Sui Dynasty, the decoration is relatively simple. After Tang Gaozong ascended the throne, he felt damp here and moved to Daming Palace. Daming Palace, located in the highland of Longshou Plateau in the northeast of Taiji Palace, is a relatively independent castle overlooking the whole Chang 'an City. Built in the eighth year of Zhenguan (634), this palace was the place where Emperor Tang Gaozong lived and handled state affairs, and was called "Dongnei". Miyagi has a symmetrical central axis pattern. The front of Miyagi is composed of Danfengmen, Hanyuan Temple, Zhengxuan Hall and Chenzi Hall, while the back is composed of the inner courtyard centered on Ethereum, with dozens of halls and pavilions such as Linde Hall, Sanqing Hall, Dafu Hall and Qingsi Hall. The whole Daming Palace is 1.5km wide from east to west, 2.5km long from north to south, and covers an area of about 3.2km 2, making it the largest of the "three palaces". Xingqing Palace, located in the east of Waiguo City, was originally the official residence of Emperor Xuanzong of Tang Dynasty when he was the king of Linzi in his early years. In the second year of Kaiyuan (7 14), it was renamed Xingqing Palace. In the 14th year of Kaiyuan (726), it was expanded and merged with the surrounding palaces and temples. Completed in the sixteenth year (728), it was called "Nannei". In the 13th year of Tianbao (754), palace walls and towers were built to form a small castle. At the same time, a waiguo wall was added to build a city between Daming Palace in the north and Furong Garden in the south, which is convenient for the palace people to sneak. Tang Xuanzong and Yang Guifei lived here for a long time. After the prosperous Tang Dynasty, its status was reduced and it became the place for the Empress Dowager and the Empress Dowager. Xingqing Palace is1.250m in length from north to south,1.075m in width from east to west, 4.6km in circumference and about1.35km2 in area, which is the smallest of the "Big Three". There are doors on all sides of the palace wall, and the main entrance Xingqing Gate is in the north of the Western Wall. The palace is dominated by gardens, not symmetrically arranged according to the central axis, so it has the nature of leaving the palace. Longchi is the main place in the south, surrounded by pavilions such as Jingjin Building, Calyx Xianghui Building and Chenxiang Temple. There are a number of palaces in the north, such as Xingqing Hall, Nanxun Hall, Changqing Hall and Datong Hall. At the end of the Tang Dynasty, Xingqing Palace was destroyed by war, and the former site of 1958 was converted into a park, and a monument of Abe Zhongma Road was built. The main entrance of Daming Palace is called Danfengmen, and the main hall is Hanyuan Hall. There is Zheng Xuan Hall in the north of Han and Yuan Dynasties, surrounded by Zhongshu and Menxia provinces, and Hong Wen and Twelve Halls. In addition, there are more than 30 other halls, pavilions and temples. Since the first year of Emperor Gaozong Xianheng, Daming Palace has become the center of political activities.

According to records, Daming Palace is divided into two parts: the outer dynasty and the inner dynasty. The foreign dynasties followed the three dynasties system of Taiji Palace in Tang Dynasty, and along the north-south axis there were the Han and Yuan halls of the great dynasty, the Zheng Xuan hall of the Japanese dynasty and the Chen Zi hall of the long dynasty. There are several halls and attics on the east and west sides of the three halls. Some official institutions are attached to overseas Korean parts, such as Zhongshu Province, Menxia Province, Hong Wen Museum and History Museum. Part of the palace is centered on the Ether Pool. Penglai Mountain is built by the pool, and a winding corridor is set around the pool. Around the main hall, pavilions and sleeping halls are in the south of Chi.
