2. Broom: The skill of broom to ward off evil spirits is generally to lean against the bedside to protect people with low flame from sleeping. Or flogging suspected evil objects. Reminder: Bamboo broom is the best, and plastic broom is the worst. The mop doesn't work.
3. Red paper: In the past, red paper was mainly used to write Spring Festival couplets, and a small note was attached to someone else's gift package as a seal. In fact, the idea of sealing and putting red paper on the door (although written on it) are used to pray for evil spirits. In the folk, you can often see red paper cut into small strips and pasted on doors, bedside, pigsty and cowshed doors, cars, windmills, etc. to pray for evil spirits and safety. The original source is that red paper represents blood sacrifice, that is, the blood of livestock and even enemies is smeared at important positions to deter the enemy's evil spirits, and later it evolved into red paper.
