What branches of Choy Li Fut contain these forms?

Can someone please tell me what branches of Choy Li Fut contain the following forms:Ng Ying Kuen, Ng Ying Ba Qua,Fu Lung Doi Cha, Fu Pao Doi Cha, Gam Pao Doi Cha Jit Fu, Gam Pao Ping Kuen? Also, while I have a translation of the forms, I cannot find what the “Cha” stands for. Can anyone enlighten? Thank you.

Doi Cha roughly means vs.

For example, Fu Lung Doi Cha =Tiger vs. Dragon

I’m not sure which branches have these forms.

We have Ping Kuen and Ng Ying Kuen in the Lee Koon Hung branch.

However the look of these forms varies greatly amongst branches.
