First of all, this legendary custom is not the northeast corner, but lighting candles in the southeast corner of the tomb. If the candle in the southeast corner goes out during the action in the tomb, it means that the action must be terminated. Grave robbers must put their money back and kowtow before they can leave safely, otherwise some strange disasters will happen. Even if the candle doesn't go out, you can't move on when the chicken crows. Does it sound gloomy? Let's discuss whether this rule is true or not.

First of all, we need to know where this legend came from, because this sentence appeared in various plots or movies changed by ghost blowing lights novels recently, so this sentence became popular, so we don't know the origin of this sentence, but from the common techniques in novels, this sentence has no scientific basis, but from another scientific point of view, the oxygen in ancient tombs is generally insufficient, so it is also a good technique to light candles to see oxygen. Moreover, ancient tombs generally pay attention to geomantic omen, while the southeast corner is generally a tomb, so that place is generally a well-ventilated place, so putting candles in that place is actually based on certain judgment, not all unreasonable, which actually shows the wisdom of the ancients. They can come up with ways to test oxygen, and there are actually some scientific reasons.

So in the end, I think this legend is true or not, and there is no way to know whether something terrible will really happen after the candle is extinguished, but I am more yearning for science, so everyone should think more scientifically. The more you believe in science, the less you are afraid of some nonsense.
