Five Families Tsoi Li Hoi Fut Hung in Chinese / Japanese...

蔡李何佛雄 is the five families associated with San Soo Kung Fu.

The characters are always the same, but there are several ways these are romanized from Cantonese, Mandarin, and other dialects. Some common ones include Tsoi Li Hoi Fut Hung and Choi Li Ho Fut Hung.

If you are using a different romanization, that does not mean it's wrong. It might just be that your school is using a different dialect or romanization scheme.
