"Expert Liu, since chickenpox is contagious, I want to ask a question." Song Xiaodong stood up directly to challenge Expert Liu.
"Go ahead and ask." Although Expert Liu was impatient, he couldn't lack decorum.
"It's been two days since the first case was detected, and only people from Daohua Village are affected, with no cases elsewhere? Does this mean chickenpox only infects the residents of Daohua Village and not others?" Song Xiaodong asked.
"This..."
"To the experts present, can anyone explain this to me?" Song Xiaodong looked around at the gathered experts with ill intent.
Song Xiaodong's question made the experts present feel a bit embarrassed.
"May I know how to address this gentleman?" Expert Liu's face blushed a little as he stood up and asked Song Xiaodong.
