After three years of working as a hotel cost accountant, can I switch jobs to another hotel to work as a general ledger?

Yes. Because cost accounting and general ledger accounting are not inconsistent. Therefore, cost accounting can do general ledger, and general ledger accounting can also do cost. Cost accounting is a position responsible for cost collection and accounting, including correctly calculating costs, optimizing target costs, strengthening cost control, etc. General ledger accounting is responsible for accounting processing and preparing accounting statements, including daily accounting, reviewing accounting documents, etc.
