Blow the air conditioner! The nose is too dry and easy to bleed. Every time I wash my face, I hold water in my hand and gently suck it with my nose. Holding more meetings is a clean and moist effect. Be careful not to suck hard and drink plenty of boiled water. Eat and sleep regularly every day. Don't stay up late, and don't have too much sex, which will lead to kidney deficiency. It will also be boring. The body does not have enough minerals. If the nutrition is not comprehensive, it is easy to lack potassium. There will be no power.
