What should I use to change the hotel's electric card?

If not, it is similar to photoelectric induction. Just block it with any card. Not if necessary. But you can go to the front desk and ask him to give you an extra one, which is usually given.

Power supply wiring of the hotel: normal wiring, as long as there is a plug-in switch for incoming fire and zero line in the empty space at the gate, and a live wire-to-air connecting rod is provided (the plug-in switch allows the use of zero line and can be directly connected with zero line terminal). If the apartment hotel uses a stand-alone water heater, remember that the power supply of the water heater should not go through the plug-in switch, so as to avoid the guests finding that the water in the water heater is cold after checking in.

Matters needing attention when staying in the hotel:

1. Although the quilt cover of the hotel is changed every day, people with sensitive skin still feel uncomfortable. Ordinary people should try not to sleep naked, prepare a comfortable pajamas, and bring their own sheets below if possible.

2, even if the toilet is clean, you can't relax your vigilance. You can prepare some disposable toilet seats to indirectly isolate skin contact.

Try not to take a shower, but take a shower.

The hotel will prepare a hot water kettle for the guests. Don't drink water immediately after boiling it for the first time. Burn it once, and then burn the second pot after disinfection.
