Xianfeng years ago? ?

Xianfeng is the title of a feudal dynasty. The title of Emperor Wendi in Qing Dynasty is 157. But the "Xianfeng era" actually describes a long time ago, because in the Qing Dynasty, foreign countries had made a lot of progress in science and technology because of the Renaissance a long time ago, and China's science and technology at that time was far behind, so it had a long-ago meaning. Incidentally, the reign of Emperor Xianfeng was only 65,438+065,438+0 years, so the reign of Emperor Xianfeng only experienced 65,438+085,654,38+0-65,438+086,654,38+0 from the first year when the Taiping Revolution and the Second Opium War both took place.
