as external styles:

Tui Shou

T'ai chi Ch'uan
The “Yang Pei” style is composed by 108 techniques and is also called “Ta Chia”. The techniques are soft, fluid and continuous but in the combat application they become fast, rapid and full of force.
Tui Shou
Pushing hands is said to be the gateway for students to understand experientially the martial aspects of the Internal martial arts (內家 nèi jiā); leverage, reflex, sensitivity, timing, coordination and positioning. Pushing hands works to undo a person's natural instinct to resist force with force, teaching the body to yield to force and redirect it. Health oriented tai chi schools may still teach push hands because there is a limit to the amount of physical conditioning available from performing solo form routines, so pushing hands adds the weight of the training partner's pushes onto the legs of the student.

Shaolin Lien Pu Ch'uan
It's a simplified form of the Shaolin from North China that is useful to assimilate the basic techniques and positions of the kung fu. You start to learn it after the warm up called Pa Tuan Chin and after having learned:

blocks and defense: Fang Fa
elbow: Chou Fa
This exercise is the basic form that mus be learned and boost your coordination, body balance, stability, breathing, mental focus and prepare the student to the more advanced techniques.
Tang Lang Ch'üan
It's the popular mantis style, the hands mimic the motion of the mantis: it's a dynamic combo of fists, kicks and grappling methods. The style was created by Wang Lang in the XVII century.

Pei P'ai shaolin Ch'uan
It's a very long exercise composed by 10 forms.
