The list cites the 2019 version of the website, but that version is no longer accessible - only the 2020 version. I suggest updating the quiz to match. It involves a few citiies changing places, and removed Riyadh in favour of Shenyang. Also, it gives local names and English names. Some of the English names are accepted, some are not. E.g., the list gives Tianjin=Tientsin, but this quiz rejects Tientsin. At the same time, it the quiz accepts Calcutta (=Kolkata). I suggest that all English names given be accepted alternates.

Tientsin is not the English name for Tianjin (which is the english name), as opposed to 天津。 "Tientsin" is just a romanisation which as fell out of use.

Yes. citypopulation.de says that the "English Names" are the former names (eg Madras for Chennai, Bombay for Mumbai, Bangalore for Bengaluru), but I call them by their (now common in English) names.

If you connect all the parts of the city into one - this is how all the other cities are counted also, with all the connected towns and cities combined into one so long as they are touching. The NYC count for example takes in huge parts of the countryside, without even having to touch each other, that's the size of a small country. -Seoul is much more contiguous: https://www.dreamstime.com/high-resolution-satellite-image-seoul-metropolitan-area-south-korea-aerial-background-map-contains-modified-copernicus-sentinel-image155221570

Guangzhou absolutely does not have a population of over 60 million people.

That is absolutely insane, what is the source for that number?

The CCP?

I have not found a single source that puts it at more than 19 million, maybe you mixed up the population of Guangzhou with that of the Guangdong region?

In 2015 the World Bank made Guangzhou the world's biggest city, pipping Tokyo with 41 million. If you check it out on Google Earth the city is now contiguously joined to Shenzhen via Dongguan, as in one can walk from one end to the other on urban streets surrounded by dense buildings. Look along the east side of the Pearl River, where a vast belt of urbanity has coursed down the river. This is not to be confused with a metro (that would count 60-86 million, in an area smaller than the San Francisco Bay Area, or Los Angeles), nor a megalopolis -its one contiguous city with several different centres. The CP does not count it as one city, due to the legal jurisdictions, but it is knitting up all the transport networks into one vast system.

The same phenomenon is happening to Shanghai, which has now conjoined with Suzhou via Kunshan, a distance of only 60 miles, but 40 million people. Check it out on Google Earth, head west towards the big Taihu Lake that Suzhou sits across from.
