不忘初心，方得始终。
...whether in times of weakness or strength, whether in times of adversity or smooth sailing, our Party has never forgotten its founding mission, nor wavered in its pursuit.
无论是弱小还是强大，无论是顺境还是逆境，我们党都初心不改、矢志不渝……
We will launch a campaign on the theme of "staying true to our founding mission".
在全党开展“不忘初心、牢记使命”主题教育。
