What's the boy's soap for?

Ok, little brother (sister), brother will teach you in detail today!

Soap, picking up soap, is synonymous with "no moral integrity". Why do you say that? Because of a joke. Two men took a bath, and when they were playing with soap, their hands slipped, and the soap fell to the ground, and then they asked each other to pick it up. Don't they have to bend down to pick it up? Then, hehe, I was later admitted (chrysanthemum). Well, this is the story of picking up soap, and it is also the earliest "no moral integrity". Regret, okay? Ha ha ha, don't get to the bottom of it next time, it's not good to know too much ~
