Why is Hangzhou called Oriental Brazzaville?

Garden City-Brazzaville Brazzaville is the capital and largest city of Congo. In the south of the border, on the right bank of the lower reaches of the Congo River. This is a beautiful tropical capital. Mango trees on both sides of the street are shaded by trees; Tall tourist bananas are graceful and can be seen everywhere. Therefore, it is called "Garden City".

Maybe it's because the scenery in these two places is so beautiful! ~
