Wen Le described in detail what happened that day.
It turned out that in the tomb raiding business, before entering the tomb, one had to pay tribute to the local Earth God. In addition to some offerings, five incense sticks had to be lit.
If the incense sticks were lit neatly, it meant that one could go down. On the other hand, if the incense sticks were burnt badly, one could not go down.
That day, Wen Le and his friends followed the usual practice of burning incense and offering offerings to the Earth God before they went down. They waited for a while and saw that the incense was burned properly. Only then did they go down.
