"Letter" is an official document used to negotiate work, ask and answer questions, request approval and reply to approval matters between agencies that are not affiliated with it. "Letter" can be divided into business letters, inquiry letters, and approval letters (request for approval letters, approval letters). A letter requesting support from an unrelated agency is a "letter requesting approval", and a "letter requesting approval" is a parallel text.
