From Cambridge Dictionary: actions speak louder than words SAYING​ said to emphasize that what you do is more important and shows your intentions and feelings more clearly than what you say 行动胜于言辞。（equivalent to 说一遍，不如做一遍） “事实胜于雄辩” literally means 'evidences are more convincing than theoretically arguments). I prefer '坐而言不如起而行' since it's literally aesthetic.

actions speak louder than words强调的是“actions/事实，真相”，说一遍不如做一遍强调的是“做”，也就是实践。
