There is a design nuance in different printing typefaces for this radical. In the Kangxi Dictionary and in Korean hanja, there is a short horizontal line at the beginning of the character's second stroke. This short line does not exist in most Simplified Chinese fonts used in mainland China, except for a few cases like the character 八 as in the Emblem of the People's Liberation Army. It exists in most but not all Traditional Chinese fonts. In Japanese typeface, the presence of the short line depends on each typeface's design. The short horizontal line exists only in printing typeface, not in any handwriting form.
