The 1978 International Convention on Standards of Training, Certification and Watchkeeping for Seafarers includes a competency item for the use of the International Signalling Code among the minimum knowledge requirements for pilots of ships over 200 tonnes. At the beginning of the 19th century, maritime countries began to develop maritime signaling regulations.

The first International Signal Code was published in 1857 and has since been revised several times. The International Signals Code, adopted by the Fourth Conference of the International Maritime Consultative Organization (now renamed the International Maritime Organization) in 1965, came into force on April 1, 1969, known as the International Signals Code of 1969, and came into force in China on July 1, 1975.

The medical section is divided into two parts: requesting medical assistance and medical guidance.

The number group consists of a single letter, two letters, three letters, or a combination of letters and numbers. Each letter number set has a complete specific meaning. Monoletter signals are used in the most urgent, important or most commonly used occasions, such as "U" means "you are approaching danger", "B" means "Our ship is loading, unloading or carrying dangerous goods"; Two-letter signals are used in general-purpose situations; The three-letter signal starting with "m" is used in medical aspects.

The digital flags are all in the shape of a long trapezoid, so they are also called pointed flags. The flag is a triangular flag. The flag is also in the shape of a long trapezoid.

u" means "you are in danger". "n" means "no". "V" stands for "I need help".
