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  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.
