I think this one is the most intriguing one.

In 1862, Maogangwei was one of the bustling  villages in the Tainan area of Taiwan,  

lively enough to have a "night  market" for evening shopping.

According to some records,  on the eve of an earthquake,  

the Holy Mazu of the Tianhou Temple in  Maogangwei "descended to the planchette"  

to warn the people of an impending "great  disaster" and urged them to be cautious.

However, when the people pressed  for more details about the disaster,  

Mazu did not elaborate further, as divulging the  

secrets of heaven was considered a grave  sin and could not be explained further.

Due to the outbreak of the Dai Chaochun  rebellion starting in April of that year  

(historically referred to as the Dai Chaochun  Incident), the residents of Maogangwei did not  

associate the divine warning with a natural  disaster but rather with human calamities,  

suspecting that Dai's troops or  bandits might attack the village.

Consequently, they took preventive measures such  

as sealing doors and scattering  beans to obstruct thieves.

Unexpectedly, the disaster turned  out to be a massive earthquake,  

and these actions inadvertently  hindered escape routes.
