Is Zijin Palace Wei Zi Palace?

No, the Zijin Hall refers to the Zijin Hall in the Forbidden City, which is located in Dongcheng District of Beijing and is the abbot's palace of the Ming and Qing emperors. Wei Zi Palace refers to Luoyang City and Miyagi City in Sui and Tang Dynasties, which is located at the highest point in the northwest corner of Luoyang, the capital of God. It was built in the first year of Yang Di the Great, so the Zijin Hall is not Wei Zi Palace.
