Before the water is cut off, I usually put a few pots of water at home for family use. If the water is cut off for a long time, the drum of the washing machine will be filled with water for a rainy day. If there is a power failure, you will usually get several charging treasures. There is no electricity at home, and your mobile phone can't be dead. Others can buy candles, and playing mobile phones under candles has different styles.
