How it works

This phrase serves as an introductory clause, emphasizing that the preceding information or context provides clear and undeniable evidence for the conclusion that follows. It is typically followed by a statement explaining what is being demonstrated or proven. '这' (zhè) refers to the subject (often implicitly the previous context), '充分' (chōngfèn) means 'fully' or 'adequately', and '说明' (shuōmíng) means 'to demonstrate' or 'to explain'.
