How it works

This is a common introductory phrase used to emphasize a conclusion or an observation derived from previous information or evidence. '这' (zhè) means 'this', referring to the preceding context. '充分' (chōngfèn) is an adverb meaning 'fully' or 'adequately'. '说明' (shuōmíng) is a verb meaning 'to explain' or 'to demonstrate', and '了' (le) is a perfective aspect particle indicating the completion or realization of the action, often implying a resulting state or conclusion. The phrase is followed by the point being demonstrated.
