Those who study Chinese history like me remember that the northern part of Beijing was where the kings and nobles lived!
Since ancient times, the Chinese have distinguished between areas where kings and nobles lived and areas where commoners lived.
So, the northern part of Beijing was home to the ruling class and the wealthy, while the southern part was home to the poor and common people.
Oh, I see! I never knew this fact; my exploration is then right. Thanks for your insightful comment with such interesting facts. That's why I found all the remarkable things in the northern Beijing than the southern part of the city, but still I have to explore a lot in the southern part as I have not been there so many times, except the Daxing International Airport, which is almost at the end of Beijing in the southern part.
I remember that in Dhaka, Bangladesh, there were also separate areas for rich and poor people!
For Dhaka, previously, the old Dhaka was for the businessmen who made them richer than the other parts, but now old Dhaka is not like that, with much crowdiness, with a dirty environment, with dense and old buildings. The new Dhaka is much more gorgeous, where a mix of people live now. Only the richest part of the City is the Gulshan-Banani Region, where you can find the best modern iconic view of the city, and it is also the most expensive part of the city.
Thanks again for your kind, informative comment.
