长期以来汉镜以镜钮为中心向四周放射的旋转式构图布局在东汉中晚期被打破，改为以镜钮为中心分别上下和左右布局，出现了直行铭文镜，观察铜镜图像的角度第一次有了明确的定点方位，这是东汉中晚期铜镜构图布局的最大变化。铜镜发展到东汉中叶，其纹饰及铭文出现了左右“轴对称式”的新布局，打破了以前以镜钮为中心作环绕式和上下左右对称式布局的“心对称式”布局。

随着两汉铜镜铸造业的发展，铜镜迅速走向平民化，成为当时普通民众的日常生活用品，因而也蕴涵着丰富的历史文化信息。唐太宗李世民曾说：“夫以铜为镜，可以正衣冠;以古为镜，可以知兴替;以人为镜，可以明得失。朕常保此三镜，以防己过。”

汉代铜镜做工精良，纹饰优美，内容丰富，正如《古镜图录》中说：“刻画(划)之精巧、文字之瑰奇、辞旨之温雅，一器而三善备焉者莫镜若也”。一面面小小的汉镜不仅反映汉代的冶炼技术、铸造工艺，也反映当时人们丰富的精神生活和繁荣的文化艺术，展示出大汉帝国蓬勃发展的盛世雄风，对后代铜镜文化的发展起着承前启后的作用，在我国铜镜发展史上占有极其重要的地位。

For a long time, the rotating composition layout of the Han mirror centered on the mirror button and radiated around was broken in the middle and late Eastern Han Dynasty. It was changed to the vertical and horizontal layout with the mirror button as the center. A straight inscription mirror appeared. Once there was a clear fixed position, this was the biggest change in the composition of the bronze mirror in the middle and late Eastern Han Dynasty. Bronze mirrors developed into the middle of the Eastern Han Dynasty, and their decorations and inscriptions appeared in a new "axial symmetry" layout, breaking the previous "heart symmetry" layout that used mirror buttons as the center to surround and symmetrical up and down.

With the development of the casting industry of bronze mirrors in the Han Dynasty, bronze mirrors quickly became civilians and became the daily necessities of ordinary people at that time, which also contained rich historical and cultural information. Li Shimin, Emperor Taizong of the Tang Dynasty, once said: "A husband uses copper as a mirror to get his clothes straight; to use ancient times as a mirror to know the rise and fall; to use people as a mirror to know gains and losses. I always keep these three mirrors to prevent myself from passing."

The bronze mirrors of the Han Dynasty are exquisitely crafted, beautifully decorated, and rich in content. Just as the "Ancient Mirror Illustrated Records" said: "The exquisite depiction (drawing), the magnificence of writing, and the gentleness of the purpose are all one thing but three good preparations. ". A small Han mirror not only reflects the smelting technology and casting craftsmanship of the Han Dynasty, but also reflects the rich spiritual life and prosperous culture and art of the people at that time. It shows the flourishing and prosperous style of the Han Empire, and plays a role in the development of the subsequent generations of bronze mirror culture. The role of linking the past and the future holds an extremely important position in the history of the development of bronze mirrors in China.
