I also want to clarify the “electric qi emission in just 3 months” so no one gets the wrong impression. It doesn’t mean that after 3 months you will be able to go around zapping people at will like Pak John Chang, Master Zhou Gan Sheng or Master Jiang Feng.
You first need an activated dantian, which usually takes 18 months in a healthy person, or you can get a master to activate it instantly like Stephen in the video did. Then you need to have channels opened (amongst other things) which takes a lot of time from practice, or can be temporarily opened instantly by a master. Then you need a lot of qi, and the right type of qi. Again, this takes a lot of time to accumulate from your own practice, or a master can inject some of his own qi for you to use for faqi.
So after 3 months even if you have help from a master, you will either emit the tiny amount of qi that you have accumulated and you will only be able to emit it once, or the qi that he has given you. Once you leave won’t be able to faqi by yourself as you need to replenish the amount of qi needed to do it, which will take a long time at a beginner level.
This is a long journey, so enjoy the ride.
