Extended data:

Flag semaphore (English: flag semaphore) is a communication method that uses hand flag or flag to transmit signals, which can be divided into single flag and double flag. Also called "semaphore" or "semaphore communication". When the distance is long, use binoculars or binoculars to extend the sight distance.

China Navy's signal communication uses international flag gestures and Chinese Pinyin to complete information transmission.
