Deng Xiaoping is the main architect of the economic reforms. He abolishes the idolization of political leaders; during his lifetime, his portrait appears on posters only very rarely. This Deng-quotation is illustrated with a photograph of a flower arrangement.
The full quotation, from a speech during Deng's 1992 Southern Tour:
In upholding the line, principles and policies formulated since the Third Plenary Session of the Eleventh Central Committee of the CPC, it is essential to adhere to the principle of "one central task and two basic points". If we did not adhere to socialism, implement the policies of reform and opening to the outside world, develop the economy and raise living standards, we would find ourselves in a blind alley. We should adhere to the basic line for a hundred years, with no vacillation. (translation: https://dengxiaopingworks.wordpress.com)
