Chengdu and Seoul land in a broadly similar monthly budget bracket. Expect a language curve either way — Mandarin Chinese in Chengdu, Korean in Seoul. Both have full set-up guides below, so the real choice comes down to climate, career field, and the lifestyle you're after.
Prices are curated local figures shown in their own currency. USD totals and “% cheaper” claims use approximate exchange rates to put both cities on one scale — rough guidance for budgeting, not exact quotes. Ranges are averaged; annual rents are shown per month.
Chengdu and Seoul cost about the same month to month once rent and everyday spending are combined.
Both run on local + English at work, so the edge comes down to your sector. Chengdu: Electronics & semiconductors, Video games & digital entertainment, Aerospace & aviation. Seoul: Technology & electronics, Entertainment & K-culture, Gaming.
Chengdu feels like “Western China's capital — teahouses, no car plate lottery, half the cost base, and extra work-permit points just for being here”, while Seoulis “Hyper-connected megacity — palaces and street food beside K-pop, all-night cafés and the world's fastest internet”. Climate is a real differentiator: Chengdu — a cloudy basin with the fewest sunshine hours of any big chinese city: humid 33°c summers, mild damp winters, and grey skies much of the year. Seoul — continental monsoon — hot humid summers, cold dry winters, four seasons.
