不忘初心、牢記使命

to remain/stay true to the Party's original aspiration and founding mission

例句：我們黨要求全黨同志不忘初心、牢記使命，就是要提醒全黨同志，黨的初心和使命是黨的性質(zhì)宗旨、理想信念、奮斗目標(biāo)的集中體現(xiàn)，越是長期執(zhí)政，越不能丟掉馬克思主義政黨的本色，越不能忘記黨的初心使命，越不能喪失自我革命精神。

——摘自習(xí)近平在主持中共十九屆中央政治局第十五次集體學(xué)習(xí)時(shí)的講話，2019年6月24日

譯文：The requirement to stay true to the Party's original aspiration and founding mission is to remind all Party members that the Party's nature, ideals, convictions, and goals manifest themselves in the aspiration and the mission. The longer our Party is in power, the more it should stick to its nature as a Marxist party, the more it should remember its original aspiration and founding mission, and the more it should carry out self-reform.
