This is a sentence in Peng Zu's regimen. Peng Zu said: Staff sergeant is different when he leaves the bed. It is better to lie down alone than to take 1000 pills. On color blindness day, the sound is deaf and the taste is cool. He who can preach, teach and solve doubts can prolong life. A day's taboo, no food at dusk (full sleep at night, loss of a day's life); January's taboo, drinking at dusk is not drunk (lying drunk at night, damaging January's life); One-year-old taboo, dusk will be far away (one-year-old died, no longer raise it); A lifelong taboo, you must protect your breath at dusk.

The dusk behind is probably enough sex. Don't have too much sex, it will damage your health.
