What locals say

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

Greater São Paulo is a huge, work-driven metropolis where daily life is defined by distance, traffic, and the need to plan ahead. For many residents, the appeal is practical rather than scenic: jobs, services, shopping, and almost anything you need can be found somewhere in the sprawl. The city feels fragmented into neighborhoods and routines, with many people living a very local life even inside a giant urban region. It can be exhausting and expensive to move around, but it also offers the scale, diversity, and opportunity that smaller Brazilian cities often cannot match.

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 São Paulo
Food

Greater São Paulo is one of Brazil’s strongest food cities, with an everyday food culture built around bakeries, kilo restaurants, botecos, Japanese and Korean spots, pizza, pastries, and very strong delivery infrastructure. Eating out ranges from cheap weekday lunch menus to destination dining, and many neighborhoods have their own reliable local staples. The city is especially good for variety: immigrant food traditions, regional Brazilian dishes, and serious restaurant cooking all sit side by side. For daily life, the practical side matters most—there are countless places to grab a good meal quickly, and people often rely on neighborhood spots they trust rather than chasing trends.

Nightlife

Nightlife is broad rather than centralized, with everything from low-key bars and samba houses to clubs, live music venues, and late-night restaurant scenes spread across the metro area. Because distances are large, people often go out within their own neighborhood cluster instead of crossing the whole city for one night. The scene can be vibrant and sophisticated, but it is also tied to logistics: ride-hailing, safety planning, and choosing where to return home from matter a lot. In practice, São Paulo nightlife is often more about specific scenes and neighborhoods than about one single citywide vibe.

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 São Paulo
By the numbers

How locals feel

On paper, the weather looks mild compared with many global megacities: no extreme cold, no harsh winters, and temperatures that are often comfortable for much of the year. Locals, though, usually talk about the weather less as ideal and more as changeable, humid, and occasionally frustrating, with fast shifts between sunshine and rain. The wet season can make commutes worse, and summer heat can feel sticky in a city already burdened by traffic and concrete. So while the statistics may make the climate seem easy, residents experience it as manageable rather than luxurious.

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.

09 · Summary

In short
