What locals say

Synthesized from upvoted comments on each city's subreddit.
Seoul

Living in Seoul feels like being in a city that runs on speed, density, and constant contrast. You can move from old neighborhoods and temple quiet to neon districts, massive malls, and subway-heavy daily routines in the same afternoon, and people seem to normalize that mix. The city is praised for being safe, efficient, and visually striking, but day-to-day life also carries pressure: high costs in some areas, language friction for foreigners, tourist fatigue in busy districts, and a culture that can feel strict about rules and manners. For many residents and long-term visitors, Seoul is exciting and convenient, but it can also feel impersonal, exhausting, and highly competitive under the surface.

“Just got back from my trip to South Korea and wow… every single day felt worth it. It’s definitely not the cheapest destination, but honestly, you get what you pay for. Clean streets, safe everywhere you go, amazing transportation, and the food? Unreal.”

“Mind you, it's not the message but the tone of the message and the general attitude. Seems they are tired of tourists there. Not sure we would like to come back.”

Zhengzhou

Zhengzhou comes across as a practical inland provincial capital rather than a destination city: a place people pass through, work in, and use as a base for exploring Henan. Living here likely means wide roads, a lot of construction and transit-oriented movement, and a city that feels more functional than charming at street level. The upside is access: it sits at the center of major rail lines and makes trips to Kaifeng, Luoyang, and Shaolin Temple relatively easy. With no Reddit discussion provided, the picture is necessarily thin, but the travel-guide framing suggests a city defined by convenience, not spectacle.

Food & nightlife

Seoul
Food

Seoul’s food scene comes across as dense, affordable in the street-food sense, and always on. People talk about kimbap, salt-grilled pork, gomtang, anju with soju, convenience-store snacks, and restaurants that stay open 24/7, plus the city’s comfort food culture around cafes, pojangmacha tents, and late-night eats. It is also practical and hyper-local: natives rely on Naver Maps, local reviews, and neighborhood knowledge to find good spots, while foreigners often need help ordering or understanding what they are seeing. The overall feeling is that you can eat extremely well here without much planning, as long as you can navigate the language and neighborhood conventions.

Nightlife

Nightlife in Seoul seems large, varied, and very neighborhood-specific: Itaewon for late-night improvisation and international crowds, Hongdae for bars and music-adjacent energy, Gangnam for organized meetups and upscale socializing, and Euljiro for chaotic tent bars and old-school drinking. People describe a city where you can end up sitting in a pojangmacha with salarymen, drinking soju and being fed anju by strangers, or looking for a hotel at 1 a.m. after a plan falls through. The city also has a strong after-hours infrastructure—PC bangs, 24-hour restaurants, jjimjilbangs, hotel bars, and all-night districts—so nightlife feels less like a single strip and more like a system. At the same time, some posts suggest that in tourist-heavy zones the vibe can be impatient or transactional, especially late at night.

Zhengzhou
Food

The guide material does not describe the food scene directly, so the safest read is that Zhengzhou’s eating is shaped by everyday Henan city life rather than a heavily tourist-curated dining identity. A new resident would likely expect a broad mix of local noodle-and-wheat-centered staples, affordable neighborhood restaurants, and plenty of ordinary chain or mall food around transit corridors, but there is not enough source material here to be more specific.

Nightlife

No nightlife discussion is available in the source material. Based on the city’s role as a provincial capital and transport hub, nightlife is likely to be centered on commercial districts, malls, restaurants, and late-evening street food rather than a globally known club scene, but this is only a cautious inference.

Weather vs. what locals say

Seoul
By the numbers

How locals feel

On paper, the weather looks dramatic and seasonal—snow, blossoms, rain, humid summers, crisp winters—and that spectacle is part of how people describe the city. In practice, locals seem to talk about weather in terms of inconvenience and survival: summer heat that makes a simple walk feel like punishment, mosquitoes that keep getting worse into the season, winter cold that can be beautiful but brutal, and fine dust days that turn into arguments about where the pollution comes from. The positive side is that the seasons are visible and emotionally vivid; the negative side is that Seoul’s weather is often something you work around rather than enjoy. People love photographing it, but they also give each other practical warnings about AC, repellent, and masks.

Zhengzhou
By the numbers

How locals feel

There is no weather discussion in the provided source, so any statement has to stay general. Zhengzhou’s climate is typically experienced by residents in terms of hot, humid summers and cold, dry winters, and local sentiment would likely be more about discomfort and seasonal dust or haze than about pleasant year-round weather. In other words, the statistics may look like a standard inland continental climate, while lived experience often turns on extremes rather than moderation.
