The Keeper of Taboos: Folk Customs of Life and Death

The folk taboos passed down by the elders are never baseless superstitions, but rather forbidden zones of life and death demarcated by our ancestors. Do not get a haircut in the first lunar month, do not stand chopsticks upright in a bowl, do not point a mirror at the bed... Once these rules are broken, the door to the eerie will swing open. And I am the keeper who walks the boundary between yin and yang, guarding the rules and shutting the doors to these forbidden zones. — Description from novelcodex.org
