1939 Since World War II, the British government has designed three posters to inspire people. Keep calm and move on is the slogan of one of the posters, but these posters were never made public until they were found and posted in a second-hand bookstore in 2000.

"Compared with 1939 when Nazi Germany swept Europe, Britain's military action against Germany was stormy. Under the threat of a strong enemy, keeping calm is the most basic attitude, and persisting in faith and making constant progress is also a work that can't stop every day. Therefore, staying calm and sticking to it is of course the best slogan. " ——————————— He Peng Fei "Keep Calm and Move on"
