Do you have a runny nose?
Have you ever experienced the fear that your nose blew, blew, blew and flowed… The paper towel was used up and your nose was scratched, but your nose still continued?
Have you ever had such a life question: Snot is used in what? Is there a difference between yellow nasal mucus and clear nasal mucus in what? How can blow his nose gracefully? Is nasal excrement and nasal mucus what’s relationship?
All the answers should start with a sunny spring day…
