History textbooks tell us that the Tang Dynasty was very impressive, the Song Dynasty was very wealthy, and the Ming and Qing Dynasties were very powerful. But have you ever thought about it - if history is a mountain, are we climbing up or downhill? This article boldly borrows the geography teacher's "contour lines" to draw a topographic map of history. It turns out that prosperous times are not necessarily the top of the mountain, and troubled times are not necessarily the bottom. Some of the "downhill roads" you think are actually civilization secretly holding back big moves. Instead of memorizing the year names or arranging them in order, let's look at history from a different perspective - by looking at a map to understand what time actually looks like.
Purpose: Let more people understand history in an easy-to-understand way of chatting.
