I am an E-9 worker from Thailand. Recently, I opened a bankbook at Bank A, and the employee said that I had to deposit 300,000 won.

I don't speak Korean well, so I thought, 'In Korea, generally I guess you should put 300,000 won in the bankbook.' and I gave the employee 300,000 won.

When you open a bankbook in Thailand, you only pay at least 1 won, but in Korea, do you have to pay that much to open a bankbook?
