The key point of this arrangement is that the letterhead, closing, signature, and sender's name are all on the right or slightly to the right, while the inside address and salutation are on the left. If any of the above elements need to be arranged in separate lines, the subsequent line should be indented by two (or three) letters compared to the preceding line. The beginning of each paragraph in the main text should be indented by five letters, and there should be an empty line between paragraphs. This format emphasizes symmetry and beauty, and is a traditional arrangement paradigm. Currently, only a few British people like to use it.
