A set of six posters, published by the Chinese People's Liberation Army Chongqing Municipal Public Security Bureau, Legal Military Control Commission Fire Branch in 1967.
The Mao quotation reads "Our responsibility is to the people".
The text reads "When a fire breaks out, you should be calm and collected. While trying to put out the fire, you should also call the police. When calling the police, you should state the location, name, street, port, door number and what was burned."
Obviously, the fire brigade's phone number is 09.
