This request is a bit specific—it looks like you might be looking for a (konturnaia karta) for a 10th-grade China unit, but you also asked for an essay .
Since I can't physically draw on a map for you, I've written an essay that covers the exact data points you would typically need to include on a 10th-grade contour map: China: A Geographic Giant in Transition
The "Hu Line," which stretches from Heihe to Tengchong, is the most vital demographic marker on any contour map. To the east of this line, the terrain is relatively flat and well-watered, supporting over 90% of the population. This is where China’s "Great Economic Engine" resides. When filling out a map, one must highlight the three major economic hubs: the Pearl River Delta (the world's workshop), the Yangtze River Delta (centered around Shanghai), and the Bohai Economic Rim (surrounding Beijing). These regions benefit from coastal access, making China a dominant force in global maritime trade.
