The title of my speech is: study and implement the party39。s two laws, doing practical play highway. 2020 October 18, the Central Committee of the Communist Party of China promulgated the implementation of the the probity of the Communist Party of China selfdiscipline criterion and Chinese Communist Party discipline and punishment regulations. We Heyuan male passersby to respond positively to the call of the Central Committee of the party, earnestly anize the study party two regulations, truly grasp the essence and gist, and in their respective positions, to hold the bottom line of the discipline, build a strong ideological line of defense, with the courage to play, the courage to fight tough and fearless spirit, at the crucial moment well to plete the task, with practical action to test the study and implement effect Because of discipline in the * * * * * * * * * * * story. Here, let me to cast a brick to attract jade, speak about our highway. Highway line section of the road surface transformation project, last year towards the country 34 seized will be seized one of the items. To plete this arduous task, as a project management office director Comrade, keep in mind from the Communist Party membership, recognize and identify the bottom line, strict management, and strict adherence to the quality of the project. He not only set an example, honesty and selfdiscipline, but also requires the management of all the members of the ., do not eat the construction unit one meal, do not accept the construction unit a ceremony.
