cough

my cough is coming back. tomolo I have to go yu ren sheng to see the usual doc who can cure my cough. Now is my peak working period, cannot afford to fall sick, all my students waiting to have exams, and most parents increase tuition slots. So I have to teach even on weekends. But only for this 2 weeks. After their exams in school, I think parents will let them rest a while, then I can take a break too.
