Save water 1. Use clean water such as rice water, laundry water, dishwashing water and bath water to water flowers, wash cars, and scrub floors. 2. Centralized washing of clothes can reduce the number of washes; hand washing of small items and small quantities of clothes is recommended, which can save a lot of water; excessive use of detergent will waste a lot of water. Save electricity 1. Electric mosquito coils Remember to turn off the power switch of the electric mosquito coils in the morning. If it is powered on for a long time, it may not waste a lot of electricity, but if it is plugged in day and night, the life of the electric mosquito coil will be reduced by at least half. It's supposed to last three years, but yours may need to be replaced in a year and a half. 2.
