You've misspelled Ho Chi Minh City and Rangoon (which is actually called Yangon, Rangoon is the name the British gave it because they couldn't speak Burmese). And Johannesburg is far larger than the size of Durban, both in the city itself (957,441 vs. 595,061) and in the metro area (4,434,827 vs. 3,442,361).
what about The Philippines (Quezon City), India (Mumbai), Burundi (Bujumbura), Switzerland(Geneva), and Trinidad and Tobago (Chaguanas). If you implement these tell me to take out answer
