Bookstore design slogan

1939 Since the beginning of World War II, the British government has designed three kinds of posters to inspire people's hearts. Keeping calm and moving 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.

Therefore, staying calm and persisting has undoubtedly become the best slogan. " ——————————— He Peng Fei "Keep Calm and Move on"
