Senior leader Liu Yunshan has urged science and technology (S&T) workers to show greater devotion to their professional research by learning from two Chinese experts. Liu, a member of the Standing Committee of the Political Bureau of Communist Party of China (CPC) Central Committee, made the remarks Wednesday while visiting experts Wu Liangyong and Shi Changxu, who have both won the country's top science-and-technology award. Wu, 90, an architect who won the State Top Scientific and Technological Award in 2012, earned his reputation for developing the science of human settlements in China and combining it with the country's urbanization. Shi, 93, won the same award in 2011 for his research on superalloy and new alloy steel, which has widely been used to produce turbine blades for Chinese fighter aircraft. Liu praised the two S&T experts. "All science and technology workers should learn from them and make contributions to building a well-off society and realizing the 'Chinese dream' with high ambitions, concrete steps and concentration on research work," Liu said. Meanwhile, Wu advised the government to focus on constructing a team of urban architects, planners and designers while boosting the abilities of city managers. Shi expressed his hope that more efforts will be made to intensify research on major strategic topics concerning the country's long-term development while nourishing talents who can devote themselves to scientific investigation. In addition, Liu called on Party and government departments at all levels to implement talent-promotion policies and create a sound environment for science and technology workers to grow and make full use of their talents.
