To make the campaigns of public health more effective and far-reaching, Miss Ping On, an "official agent" to promote good hygiene, was created by the Public Relations Office in 1958. Miss Ping On was a cartoon figure derived from the Chinese characters, "good health" and "safety".

A colourful Miss Ping On in different poses with different messages teaching simple hygiene habits was depicted in a regular series of posters issued by the government. In fact, she appeared in almost all government posters that publicized health education between the late 1950s and early 1960s.
