Which font has the best bold effect?

The best effect of bold words is italics, because according to the normal specifications and document typesetting format requirements, the first-level title is bold, the second-level title is italics, and the third-level title is imitation of Song Dynasty. In the process of writing letters, the bold type itself is relatively thick, which will be particularly prominent if family members get married. If family members are required to imitate Song Ti as the font of the text, if the whole text is black, then the italics as the secondary titles will be more detailed.
