The given sentence (Indirect Speech) is an Assertive Sentence. Since this sentence contains the sense of Universal Truth, when changing to Direct Speech, we remove the Conjunction 'that' and use Inverted Commas, and despite the Reporting Verb being in the Past Tense, there is no change in the Tense of the Reported Speech.
