When appearing at the left side of a Chinese character, it transforms into 牜, with the last two strokes switching their order and the last stroke becoming a rising stroke rather than a horizontal stroke.
In the Kangxi Dictionary, there are 233 characters (out of 49,030) to be found under this radical.
