Why is the ancient Zhongshu Province also called Wei Zi Province?

In ancient China, Wei Zi refers to Wei Zi Garden, which has been used to describe the residence of the emperor, namely the imperial palace, since the Han Dynasty. In the Tang Dynasty, Zhongshu Province was located in the Imperial Palace, which was the highest administrative center of the country. New Tang book? "Guan Bai Zhi Er" contains: "In the first year of Kaiyuan, the book was changed to Wei Zi Province, and the life letter was purple emblem. "

The flower name of Lagerstroemia indica is homophonic with "Wei Zi", and its shape is similar, except that a grass prefix is added to "Wei Zi". Coupled with the charm of the plant itself, it is "durable, gorgeous and lovely", so when Zhongshu Province was renamed as Wei Zi Province, Lagerstroemia indica was widely planted in the palace, and the cultivation history of Lagerstroemia indica in China entered a new era, and Lagerstroemia indica was treated with an unprecedented high standard in history.

Although a few years later, the name of Wei Zi was abandoned and renamed Zhongshu Province, the influence of Wei Zi Province and Ziweiling was far-reaching. Ziwei flower not only took root in the imperial palace, but also spread to the people. All officials working in Zhongshu Province like to call it Wei Zi. For example, Du Mu, a poet in the Tang Dynasty, was a calligrapher in China and was called "Du". Bai Juyi, a poet in the Tang Dynasty, once wrote a poem, "Si Lun's adult is quiet, and the bell and drum tower are long." Sitting alone in the dusk, who is the companion, and the opposite of the flower is Lang ",which also describes the close relationship between the flower and the government.
