In terms of hydraulic systems, East Africa can only rank fourth in the world, while the regions before East Africa are Europe, the United States, and the Far East Empire.
The first two are easier to understand, after all, Europe and America developed their industries early. Europe itself has a comparatively developed hydraulic system and historical accumulated advantages, while the United States also benefits from its geographical advantages, with lower costs for hydraulic construction.
As for why the Far East Empire can rank ahead of East Africa, it's because of the Far East Empire's long-standing historical heritage, with a rich legacy. In the history of the Far East Empire, the records in the field of hydraulic construction are more profound than those of most countries.
Of course, there is another common reason why these three regions can rank ahead of East Africa, which is their natural conditions that are much more advantageous than those of East Africa.
