Why does "Xianfeng era" refer to a long time ago? What is the origin?

Meaning: "ancient" and "long" things.

Tip: 1840 years ago was ancient.

Commentary: Emperor Xianfeng, literate in Qing Dynasty, Aisingiorro Yining (A.D.1831-1861), crossed the ancient and modern boundaries all his life. So "Xianfeng years ago" means "ancient".

During the Xianfeng period of the Qing Dynasty, the political situation was chaotic, and external worries and internal troubles never came alone. Guangdong is located near the sea and is often invaded by foreign devils, which has brought an indelible psychological shadow to the people of Guangdong. Therefore, Xianfeng has long said that he will not forget the sufferings of the past.

I borrow the word "salty" from Xianfeng. Because of the weather in Guangdong, things that have been left for a long time are salty and smelly, and they smell strange. At the same time, Emperor Xianfeng also had a certain history. Therefore, the word Xianfeng years ago is used to represent things that have been mentioned for a long time. In fact, many words have been developed through near-sound borrowing, such as: Sweden = sleep (homophonic: Rui = sleep; Code = mattress) Genghis Khan = sweating like rain Genghis Khan beat teenagers-"sweating like rain to avoid fine sweat = sweating like rain in Zhujiang No.1 Middle School-"threw himself into the river (to borrow the homonym of Chinese characters, it means to leave behind. It used to be said that students who didn't make progress could only apply for Zhujiang No.1 Middle School. . . . .
