Welcome back.
When you think of crowded cities in our world, a few spots probably jump to mind.
NYC, USA. Tokyo, Japan. New Delhi, India. Dhaka, Bangladesh. Hong Kong, PRC. Perhaps a few others.
What probably doesn't come to mind is Taipei, Taiwan.
Yong He, Taipei (technically New Taipei City) boasts a density somewhere in the neighborhood of 40,000 people per square km.
Good enough for top 3 most densely populated places on the planet, depending on where ya look.
Wild.
Here are a couple of photos I snapped whilst exploring the area one afternoon / evening.
