The concept of "communication without drainage" comes from the ancient atrioventricular regimen, that is, the legendary "sexual intercourse". "Communication without drainage can also replenish the brain." Some western scholars scoff at this and think it is impossible! And give a "scientific" explanation: think that this is just "retrograde ejaculation", injecting semen into the bladder. I think they are too arbitrary! In fact, in the practice of sexual counseling, "retrograde ejaculation" is very rare.

On the contrary, there are many examples of "paying without leaking". However, this kind of "giving without revealing" is not the product of their original intention. Not ejaculating is actually a kind of "crossing without leaking". However, this non-subjective pursuit of non-ejaculation is more common among young people and makes them feel painful and uncomfortable. This is essentially different from the middle-aged and elderly people's active pursuit of atrioventricular health care, which can be controlled subjectively. This example is used here to illustrate that it is completely possible for everyone to understand that "paying without revealing secrets" is completely achievable!
