What self-help common sense do you need to master in rainstorm weather?

1. How to prevent indoor lightning strike: When it thunders, the first thing to do is to close the doors and windows, leaving the metal water pipes entering the house and the sewer pipes connected to the roof. Try not to dial, don't answer the phone, and don't use your mobile phone to surf the Internet. Unplug the power supply, telephone line, TV antenna and other metal wires that may introduce lightning strikes. The safe and scientific way is to install lightning arresters on power lines and do a good job of grounding. Don't take a bath with a solar water heater in thunderstorm weather.

2. If you can't swim: Chinese medicine reminds you that when drowning happens, you can take the method of self-help when you are unfamiliar with water: besides calling for help, you can take a supine position with your head tilted back so that your nose can breathe out of the water. Shallow exhalation and deep inhalation. At this time, don't panic, don't raise your arms and flutter, and let your body sink faster.
