China vs South Korea for TEFL: What You Need to Know Before You Pack

Leaving a draining job to teach English abroad is a bold move — and one that more and more people are making. Whether you want a fresh start, a cultural deep-dive, or a chance to finally save some real money, China and South Korea are two of the most rewarding destinations on the TEFL map. But picking between them is not always easy. From climate and visas to taxes and internet access, the practical differences can shape your entire experience.

Climate: Know Your Limits

If you’re used to mild UK summers, both countries can feel intense. South Korea has hot, humid summers with monsoon rains, while much of China experiences scorching heat, especially in central and southern cities. If temperatures above 40°C make you flounder, look for cities with more moderate seasons — coastal areas and northern regions tend to be easier. But don’t expect cool summers anywhere in East Asia. Pack light layers, stay hydrated, and plan for air-conditioned escapes.

Passports and Paperwork

Dual nationality can be a useful card. If you hold both UK and Irish passports, check which one gives you smoother visa processing in each country. Some teaching programmes in South Korea have historically favoured applicants from certain English-speaking countries, and your passport choice can affect eligibility for official teaching positions. Ireland’s EU status may also offer certain advantages. Always verify current visa rules with the embassy before you commit.

Taxes: Read the Fine Print

Tax systems in China and South Korea are very different from the UK’s. In South Korea, teacher income tax rates can be surprisingly low — sometimes around 3–6% — but this often depends on your employment status. Some schools classify teachers as contractors, which can lower your tax rate but may also mean fewer benefits. Make sure you understand whether your contract is for one employer only, as that can be a condition for the lower rate.

In China, salaries are often higher in real terms, and the lower cost of living can make it easier to save. But tax rules vary by city and contract type. Keep digital copies of everything, ask for clear payroll breakdowns, and consider getting advice from someone who’s already taught in the country.

Healthcare and Air Quality

South Korea has an excellent healthcare system, but you’ll likely need to register for National Health Insurance once your teaching contract begins. Most schools help with this, but check your contract carefully. Air quality, however, is not always better than China — fine dust can be a real issue in South Korea, especially in spring. If pollution is a concern, look into air purifiers and quality masks.

In China, many schools provide private health insurance, but public hospitals can be overwhelming. It’s worth getting international health insurance as a back-up, even if your employer offers coverage.

Staying Connected: The Great Firewall

One of the biggest culture shocks in China is internet censorship. WhatsApp, Facebook, Google, and many Western apps are blocked. If you have an anxious parent waiting to hear from you, this can be stressful. The good news? A reliable VPN installed before you arrive can help you stay connected. Many teachers also switch to WeChat for daily communication with family. South Korea has no such restrictions, so if seamless contact matters a lot, that may be a deciding factor.

Saving Money and Lifestyle

Generally speaking, China offers a lower cost of living, and with the yuan’s exchange rate, many teachers find they can stash away a healthy amount each month. South Korea is more expensive, especially for housing and food, but salaries are competitive. Your saving potential also depends on your lifestyle. Do you want to travel every weekend? Eat out constantly? China is easier on the wallet, while South Korea offers more convenience, late-night food, and a highly modern, comfortable way of life.

The Bottom Line

Both China and South Korea can give you the fresh start you’re looking for. If your priority is maximum savings and you’re ready to deal with a few connectivity headaches, China is an incredible option. If you value ease of communication, healthcare access, and a highly organised daily life, South Korea might feel more comfortable.

Talk to teachers already on the ground, read current visa guides, and trust your own priorities. Either way, you’ll walk away with new skills, new perspectives, and a lot more confidence.
