8.B.1 - Po Pei - Basic idea:

From Fighting Stance.

When close to opponent, execute Various Po Pei variations, with full arm/elbow control and following Chasing Step.

8.C.1 - Fook/Wu - Jam/Po Pei:

From basic Poon Sau (4.C.2) to 2. Attack (Inside Pak) (6.C.1)

Against A's 2. Attack (Inside Pak), B lowers inside Fook into Fook while rotating forward, creating room for Noi Bong to release into Wu. Upon impact B raises arm to horizontal while turning away, A's Fook converts fook into Jam and Wu into Po Pei - (Low palm "push"/low punch), before landing with Short Step.

8.C.2 - Scissors Gaan Defense against Po Pei:

From basic Poon Sau (4.C.2) to 2. Attack (Inside Pak) (6.C.1)

Against A's 2. Attack (Inside Pak), B lowers inside Fook into Fook while rotating forward, creating room for Noi Bong to release into Wu, which drags A's arm to execute the above Jam/Po pei. Upon intension A counter attacks with Scissors Gaan, releasing B's Jam into Pak (3.S.N.T.) against high Gaan, and A's low Gaan guides B's lower attack into a "Lifting" Chaan (9.C.K.).
Due to the centered elbow at A's High Gaan, A controls B's Lifting Punch, and

executes "Monkey" Jut to release Chaan, with two possible outcomes:

If A's Jut is towards B's elbow, B executes Lap Dar upon diagonal contact due to Chaan release, which forces A into Bong and principle Wu (3.C.K.) to avoid over rotation.

If A's jut is across B's attacking line, B is forced into Bong and principle Wu (3.C.K.) to avoid over rotation.

8.C.3 - Inside Taan control:

From slightly rotated IRAS
A from Bong and principle Wu (3.C.K.) - B from Inside Fook/Lap.

Prior to start, A lowers Wu into a non contact Fook.
When B releases the Lap contact, A executes Fook and Taan with a following Short Step.

8.C.4 - Kam Na Sau:

From slightly rotated IRAS
A from Bong and principle Wu (3.C.K.) - B from Inside Fook/Lap.

Prior to start, A lowers Wu into a non contact Fook.
When B directs the Lap contact/pressure towards own Inside Fook, A executes Fook, however meets the Lap arm and converts Fook into Kam Na Sau control hand, and releases Chaan with a following Short Step.

8.D.1 - Fighting situations: - Program 8.C.1 - 2 :

Always from Fighting Stance..

If opponent, upon diagonal contact raises the arm to horizontal while turning away, execute Jam to Po Pei.

If opponent, upon diagonal contact tries to control arm and do low attack, execute Scissors Gaan.
