chen tai chi- hu lei jia, zhao bao

[taichi4eva]

Currently, I'm learning a Chen Taiji set that resembles pao chui, but it has been modified to make it more applicable to fighting. The person that I am learning from learned the set in Vietnam (which could explain the changes), and says that his master only taught this set, and a shorter form that he never learned.

I have read about hu lei jia and zhao bao, and notice that these frames of Chen Taiji have only one set. Can someone shed more light on these two frames?

Thanks in advance!
