What locals say

Synthesized from upvoted comments on each city's subreddit.
Greater Tehran

Greater Tehran feels like a huge, layered metropolis where routines are shaped by traffic, bureaucracy, and the pressure of rising costs, but also by a strong sense of neighborhood life and adaptability. Daily life can be exhausting: commutes are long, sidewalks and transit are uneven, and many people build their schedules around avoiding congestion and dealing with practical hassles. At the same time, the city offers dense access to jobs, universities, services, and a food culture that runs from street snacks to serious restaurant scenes. People who live here often describe it less as a polished capital than as a place you learn to navigate through endurance, networks, and small daily workarounds.

  • Air pollution and winter inversion4
  • High cost of living4
  • Bureaucracy and administrative friction3
  • Crowding and urban stress3

Nanjing

Nanjing comes across as a big, historically important city that is still easy to move through if you know the metro and the main districts. Daily life seems to revolve around university neighborhoods, coffee shops, language exchanges, and practical errands rather than a huge foreigner scene. People mention good food, pleasant places to bike and wander, and a city that can feel welcoming if you plug into student or expat circles. At the same time, newcomers often say it can be harder to make English-speaking friends here than in some other Chinese cities, and summer heat is a real drag.

Common complaints
  • Hard to build an English-speaking social circle8
  • Summer heat2
  • Foreign-friendly nightlife is limited or scattered3
  • Short-term housing near campuses can be difficult2
  • Dealing with incidents requires evidence and local know-how1
Common praises
  • Friendly locals and openness to language exchange9
  • Strong university and student presence7
  • Good food and coffee spots6
  • Walkable, bike-friendly exploration4
  • Historical and scenic places5

Food & nightlife

Greater Tehran
Food

Tehran’s food scene is broad and highly practical: kebab shops, tahchin, stew houses, sandwich counters, bakeries, and endless tea-and-cafe stops sit alongside more contemporary restaurants and upscale dining. Many residents eat a mix of home cooking and quick neighborhood meals, but there is real variety if you know where to look, including regional Iranian dishes, fast food, and street snacks. Eating out is also shaped by inflation, so people often talk about finding good value as much as finding good flavor.

Nightlife

Nightlife in Tehran is constrained by law and social rules, so it does not look like a conventional late-night party city. Instead, social life often shifts to private homes, family gatherings, cafes, restaurants, and informal hangouts, with younger residents making the most of limited public options. When people talk about going out, they usually mean evening walks, cafe time, dessert spots, or meeting friends quietly rather than clubbing in the usual sense.

Nanjing
Food

The food scene in the Reddit sample feels practical, varied, and neighborhood-based rather than flashy. People ask for budget places, local Chinese food with beer, and even an Iranian restaurant, while one commenter singles out Commune’s Thai salted egg yolk wings as unusually good. Coffee and casual drinks also come up often, which suggests a city where eating out is part of everyday social life. The overall impression is that you can eat well, especially around universities and expat-friendly areas, but you may need local tips to find the best spots.

Nightlife

Nightlife seems modest but usable, with a few known bars and a small foreigner hangout network rather than a huge club scene. One commenter recommends Secco on a Friday night, and others ask about the go-to laowai bar or weekend events like BBQs and magic shows at Finnegans Wake. The vibe appears more after-work beer, live music, and social meetups than late-night spectacle. For many people, nightlife in Nanjing seems tied to meeting friends, language exchange, or a mixed local-international crowd.

Weather vs. what locals say

Greater Tehran
By the numbers

How locals feel

On paper, Tehran’s climate can look appealing because it has distinct seasons and dry air much of the year, with hot summers, cold winters, and mountain views. Locals, though, usually describe the weather through discomfort: summer heat, winter cold, and above all the pollution that turns otherwise ordinary days gray and unhealthy. The basin geography means weather is often discussed together with smog, visibility, and whether the mountains are even visible from the city.

Nanjing
By the numbers

How locals feel

The weather sentiment is mixed but tilted negative in summer. The city can look beautiful in cherry blossom season, and people clearly enjoy outdoor exploring, biking, and photo walks, but one comment bluntly notes that July and August are not ideal because it gets too hot. That suggests locals and visitors appreciate the seasons, yet summer humidity and heat are memorable enough to affect travel planning. The vibe is that Nanjing’s weather is best enjoyed in spring and autumn, while midsummer is something to endure.
