Thanks for the translation! 😁
The Hei Yao character are just a proxy of many (MMA) fighters nowadays, just like Xu Xiaodong. They tend to patronize and look down on their opponents. I don't say that he's completely wrong, but he's not right either. Indeed, there are so many fake martial arts masters, but it doesn't mean there is no real master. The real masters knows about themselves that if there are went into a fight, there is a huge change that they kill or heavily injured someone. That's why real Masters don't fight (and they don't boasting either).
This also related to chi/ki (spiritual energy) that usually trained by the masters. In simplest explanation, it is the accurate techniques of breathing. For example, Mas Oyama broke the Buffalo's horn, or when he clean cut the neck of a bottle. The real reasons that less and less people practice this nowadays are lack of patience and it's a hassle for many people.
About Shaolin temple. Both Northern and Southern were burned several times throughout history. And the surviving martial arts went less and less complete. Because most of the survivor are the lower ranks while the masters died defending their escape attempt. So much for martial arts against an army (and firearms). Eventually the Shaolin's mixed with the common people's martial arts.
Yup, just like wushu, pencak silat have myriad of styles; and most of them also suffered to the same thing: stubbornness of perfect form - that usually ineffective moves in the modern days. "The form (kata) is dead, but the human (user) is alive."
About pressure points. This was also common in Chinese martial arts, even in silat. This pressure points are exactly the same thing with that's been taught in acupuncture-acupressure-reflection massage. In can be used to alter one's blood circulation or nervous system, it can stiffen or even lock a joint. But to apply it on real fight, it will require a huge amount of training, discipline and chi, compared to when it used for massage. In the end most of people deem this as unpractical in combat.
Oh, yeah about "cock", it's not wrong per se, but it may translated better as "rooster".
