1. One-month stay for guaranteed tourist C32 visa,

2. One-month stay for unguaranteed tourist C39 visa or multiple-entry visa,

3. The stay period for the C33 visa for medical tourism is also one month.

These are all acceptable. It should be noted that the C39 and C33 visas in South Korea can be extended if they meet the extension conditions. Since C32 is a guaranteed tourist visa, you must return to the country on time, otherwise you will not have the deposit.
