Interesting observation while Xingyi traditionally is known to be taking advantage of stepping to improve its punching power. In boxing the cross is more powerful than the jab, in Karate the reverse punch is more powerful than the lead punch, and the same is with Xingyi. From my observation, most practitioners stamp the rear leg forward and broken the hand, torso, and leg unity in a reverse punch that is all.

There is two arrow punches in the crashing fist, one is done with Shun Bu, the other one is done with Ao Bu but in half a step.
Shun Bu can be described as at the end of the movement the forward leg and the forward arm are on the same side, left leg and left hand, or right leg and right hand. Shun literally means in the same direction, or downstream,
Ao Bu can be described as at the end of the movement the forward leg and the forward arm are on different sides, left leg and right hand, or right leg with left hand. Examples of this are: in Taijiquan which is commonly translated as twisted step, or reversed punch in Karate, or a cross in Boxing.
Many thanks and look forward to your suggestions.

If everything arrives at the same time, you are no longer a whip. . . .
There are actually several dissertations on the biomechanics of Taiji and whole-body power in CIMA published by sports scientists in Taiwan that prove fajin is indeed sequential beginning from the feet all the way up to the hands, or moving in a "kinetic chain," as they call it. So there's really no point in debating who's right here.

The results suggested that the final stage, lead toe in, was the most important in delivering powerful straight punches, and boxers used trunk rotation to transform vertical ground reaction force to horizontal punch force. . . .
Movement Pattern of Straight Punches
GRFs of both legs from each participant were shown in the middle and the bottom panels of Figure 1. The patterns of GRFs of both legs were similar among every participant. Figure 1 revealed that punching phases or movement pattern of straight punches could be divided into 3 stages, i.e., starting position, lead toe off (LTO), and lead toe in (LTI). . . .
(3) Lead Toe In (Figure 1c-1d): the final stage started when boxers began to bear weight on the lead leg and ended when the fist hit the target (Figure 1d). At this stage, boxers used the lead leg as a pivot point and executed straight punches such that only lead leg supported the body weight and the rear leg bore no GRF. At this stage, GRF of the rear leg decreased, while GRF of the lead leg increased, which was exactly opposite from the starting position or the first stage. From Figure 1d, the directions of GRF of the lead leg and punch force were not in the same direction. As a result, the participants utilised the lead leg as a break to stabilise their movement. The time analysis of the final stage differed greatly among the participants ranging from 29.5% to 45% of total punching time. LTI was extremely important in delivering powerful straight punches. As seen in Figure 2, the kinetic chain of straight punches occurred after 70% of total punching time meaning that the whole kinetic chain was created and ended at this final stage. . . .

The trunk rotation played crucial role in LTI or the final stage of punching. At LTI, the displacement angle of trunk rotation was greatest (at 80% of punching time). Angular velocity of trunk rotation increased as GRF of the lead leg increased while GRF of the rear leg decreased. The lead leg acted as a pivot point, while the rear leg pushed the trunk and the whole body of boxers forward to create punching momentum and, thus, punch force. Therefore, trunk rotation mechanically transferred vertical ground reaction forces to horizontal punching force. The peak angular velocity of trunk rotation was achieved at impact. . . .
The final stage, which was lead toe in, was crucial in delivering powerful force.

He suggests twist step and favorable step.

Here are examples of twist-step in sports.
