The rich businessman was sucked by the bathtub and drowned in the 0.9-meter-deep massage pool, and died instantly.

What you think is a little simple. But the fact is, this kind of accident is so rare, who would have thought it would happen? Therefore, according to my analysis, in that case, people have already panicked and don't know what to do. Who would have thought of using a breathing tube? Besides, it was impossible to prepare this thing at that time. To say the least, even if there is this thing, it may not work, because the person who is sucked has long been scared and doesn't know how to use the breathing tube. Some analysts said that there was also a problem with the rescue method at that time, that is, the rescuer could not pull up straight, but should lean sideways to make a gap between his body and the water outlet, which would reduce the suction.
