Where should I setup a bank account in Busan?

"Before retiring in Busan, expats should know that the cost of living is relatively low compared to other major cities in Korea, but higher than in many Western countries. They should be aware that the primary language spoken is Korean, and while English is taught in schools, not everyone is fluent. Expats should familiarize themselves with the Korean healthcare system, which is universal and high-quality, but may require some out-of-pocket expenses. They should also understand the visa requirements for long-term stays in Korea, which typically involve proving a steady income or significant savings. Expats should be prepared for a different diet, as Korean cuisine is heavily based on rice, vegetables, and meat, with a strong emphasis on seafood due to Busan's coastal location. They should also be aware of the cultural importance of respect for elders in Korea, which is deeply ingrained in social interactions. Expats should familiarize themselves with the local customs and etiquette, such as removing shoes before entering a home and not writing a person's name in red ink, which is considered bad luck. They should also know that public transportation in Busan is efficient and affordable, with a comprehensive network of buses, subways, and taxis. Lastly, expats should be aware that the climate in Busan is temperate, with four distinct seasons, including hot, humid summers and cold, dry winters," mentioned another expat when asked about moving to Busan, Korea.
