If you just translate it as ‘Issue Power’, then yes, anyone can do that, a five year old kid, your grandma, can both ‘Issue (their respective amount of) Power.
But that’s the point of why martial artists, who were naturally secretive and dismissive of strangers, would name something that’s highly specialized and specific, such a mundane or generic term.
But, fortunately we have arts that have no longer been kept so secretive, and we have more specific terminology that gives us more insights into what ‘Fa Li/ Fa Jin’ is actually referring to.
Which is a specific usage of the whole spinal column, as if it was like a limb, like a third leg. Everyone knows that to fight, the amount of power you can put into a strike, is basically dependent on how fast and powerful a limb can bend and unbend. So in order to be even more efficient, what if the spinal column can be used like an extra limb, and somehow make use of its capability to bend and unbend.
This bio-mechanical movement has been dubbed ‘Xiong Yao Zhedie’ (Chest Waist Folding/Bending). Or since the movement of the spinal column is trying to motivate the flesh of the abdomen and torso to jolt upwards and send a wave of flesh moving in time with the outgoing strike, it’s also been named ‘Bo Lang Jin’ (Crashing Wave Power). Another name is because you can see the rippling movement of the spine and torso, which looks sort of like the way an inch worm scoots itself along a branch, that another term is ‘Can Yong Jin’ (Silk Worm Power).
This movement, and everything it entails, in order to get it to the point where it can effectively be used as if it were a fifth limb of your body, requires a lot of time spent towards practicing it.
This movement does seem awkward and maybe unnatural, but my teacher said that it is something that men already instinctively know, but just not in any way related to fighting. This doesn’t get mentioned, very much, if at all, because there’s a strict taboo about talking about what happens in the bedroom. But basically it’s the action of the spine and pelvis that one uses to thrust. And using essentially the tailbone to try to ‘Poke the tip of the sword through the bottom of the sheath’.
Which is the same for using it to add power. The area around the tailbone is important, but unlike in the bedroom, it’s important to have movement initiate there, but obviously you can’t keep your intention there. So in order to learn the fluidity of movement to the point where it becomes natural and you can issue power/ spring your spine, on a mere whim, without intention on the movement, but towards the effects, it is said that “A student who is trying to learn this skill, should be locked inside the school for two years.” (Locked inside the school means kept away from trying to apply it in any sort of manner towards fighting. For a good two years it will not be something you can use in a fight. Not even in applications with a friend. Because your intention will be stuck on the movement of your spine, and not on the fight. Or on the fight, but not on your spine, and you can physically hurt your own vertebrae.)
So, two years to learn, but a lifetime to master.
