A joke about porcelain

My friend's father is a porcelain lover, and the tableware at home is Jingdezhen fine porcelain. I asked my friend's father how to tell the difference between good and bad porcelain. My friend's father picked up a porcelain plate and said, "I'm too professional, you don't understand." I will simply tell you a few tips for identifying good porcelain. " Good porcelain is thin, moist and shiny, with high whiteness and transparency. If these points can be achieved, it is basically a good porcelain. "

On this day, my wife and I went shopping in the supermarket. In the tableware section, I want to show my wife the tricks I just learned to identify porcelain. So I stared at a plate, picked it up and looked at it carefully. I said to my wife, "Look, this plate is not only thin, but also shiny. When I look at the light, the light transmittance is very high, which shows that this is a good porcelain. Let's buy a set and go back? " At this time, the shopping guide came over and said, "Mr. Wang has a good eye." This set of tableware sells well. "I am more proud. I was about to put it in the shopping cart when the shopping guide added, "And plastic ones are not afraid of falling. "
