As the saying goes, “People have three urgency.” Among them, urgency is often encountered in our daily life. When we have a sense of urine, we will choose to go to the toilet to solve.
I don’t know if you have noticed the color of your urine when you go to the bathroom. Usually the color we see in the naked eye is white or yellowish, but when you look at the microscope, you will find its color change. It has become colorful, very magical!
