The two most famous detached palaces of the Great Tang are the Ren Zhi Palace built by Tang Gaozu Li Yuan on Yuhua Mountain, and the Ren Shou Palace built by Sui Emperor Yang Jian in Lin You County during the Sui Dynasty.
The former was expanded into a new imperial palace in the 21st year of the Zhenguan era by the decree of Li Shimin and renamed Yuhua Palace. The latter was decreed by Li Shimin to be renovated this year and renamed Jiucheng Palace.
Throughout the entire historical period of the Great Tang, temperatures were higher than modern times, belonging to a warm period. In the summer, although the noble families of the Great Tang had ice storage, it couldn't compare to modern cooling methods.
Ordinary commoners were tied to the land no matter the weather; rain, wind, or scorching sun, they had to endure it all.
But it was different for nobles and the Imperial Family; they could move whenever hot or cold, and manors and detached palaces were their places of enjoyment.
