When Deng Shichang was alive, the highest rank began in the second grade, and he could never be called a "military gate". In the past, the official address was a serious matter and could not be said indiscriminately. Otherwise, it would be quite taboo. At that time, the prefect of the navy division could be called "the military gate", but it was not under the prefect, even if it was a registered prefect. Deng Shichang is just a duct tape, not to mention the related film and television works.
