Dear Lihua's uncle
I hear you are an engineer and you are busy with your work every day.Sometimes you have to work late at night.You often smoke in order to reduce your pressure.I don't think it's right to stay up late and smoking is bad for your health,too.First of all,you should get enough sleep.If you often go to bed late,you won't concentrate better or be able to work well.Besides,you shouldn't smoke too much because this harm your body.What's more,you'd better get more fresh air.Why not go outside and exercise or go for a walk every day.Finally eat three healthy meals and more vegetables and fuits.This will make you healthy and strong.
That's all for now.Best wishes.
Yours
Li Hua's friend
