A question about speed/power

[YouKnowWho]

I thought someone from of this community might have some helpful input into my actual question. It seems as though this isn't the case for this question.

Some TCMA systems such as praying mantis and Zimen are famous in speed generation. Some TCMA systems such as Baji, XYLH, Chen Taiji are famous in power generation. You should try to learn at least one style from each category before you may consider this issue. If people can just explain to you within few sentence on this subject, people in the ancient time won't need to create such systems.

Also be able to punch fast and powerful into the thin air is different from be able to punch fast and powerful on a heavy bag.

Praying mantis master Branden Lai loved to use the following test to prove his speed.

- You and your opponent both stand with right leg forward.
- You and your opponent both drop hands down next to the legs.
- You try to use your leading right hand to touch your opponent's back left shoulder.
- Your opponent tries to use his leading right hand to block your punch.
