痰盂 / Spitton

痰盂

In China,people often spit into the spitton.But the traditional spittoon can’t stop the spread of pathogenic bacteria.The bacteria can do great harm to people's
health,especially in public place.To solve this problem,we put some special liquid into the spitton.The density of the liquid is smaller than water.So,the phlegm
will sink to the bottom of the spitton.By this way,we can stop the spread of pathogenic bacteria and live a healthier life.
