Where should I setup a bank account in Seoul?

"Before retiring in Seoul, expats should familiarize themselves with the local culture and customs. It is important to research the cost of living in Seoul, as well as the availability of healthcare and other services. Expats should also consider the language barrier, as English is not widely spoken in Korea. Additionally, expats should research the visa requirements for retirement in Korea, as well as the tax implications of living in the country. Finally, expats should consider the climate in Seoul, as the city experiences hot, humid summers and cold, dry winters," remarked another expat in Seoul, Korea.
