This is because some hotels now install micro cameras in their rooms to sneak shots of guests, and sell these videos to criminals through some illegal channels, which is likely to pose a threat to our personal information security. So although it's a little troublesome, it's still recommended to turn off the lights before checking into the hotel and look at it with your mobile phone to see what's wrong, especially for girls.

In recent ten years, China's tourism industry has made great progress, mainly because people's material living standards have been greatly improved in recent years. When we travel, we will inevitably stay in hotels, so the choice of hotels is also very important to us. If we don't get a good rest in some black shops, we may also cause ourselves some troubles and affect our mood during the trip.

Nowadays, when people travel, they will choose to stay in homestays or star-rated hotels, because the accommodation conditions in these places are generally better and cleaner. Moreover, in general, these homestays and star-rated hotels have great careers, which makes people feel at ease. However, we often say that it is necessary to guard against people. In this information age, although people's lives have been greatly facilitated, our privacy has also been threatened.

We often hear in the news that a tourist wakes up in the middle of the night and finds a red dot in his room. These may be miniature cameras. Some unscrupulous vendors will use these cameras to take photos of guests' privacy, and then use this information to threaten them to seek benefits, so just in case, you must check carefully before you check in.
