Centennial Ancestral Temple Never Knots Spider Web Urban Express

Yu Baoying, Yanmen Village, Rongjiang Township, Jinyun County, called: There is an old ancestral hall in our village called Yu's ancestral hall. For hundreds of years, we have never found cobwebs in it. My 9 1 year-old grandfather can testify that this ancestral hall is usually empty and has not been cleaned regularly. My grandfather used to go since he was a child, and he always did. The ancestral temple is located on the roadside, and there will inevitably be some dust on the ground, but there is little dust in other places, such as rafters and beams. People in the village feel very mysterious. Children are scared every time they pass by the ancestral temple, so everyone wants a scientific explanation.

Trainee reporter Ye Zhi reported that the old ancestral hall was made of wood, but there were not many carved beams and painted buildings. Although it has a long history, the villagers say it doesn't look shabby. The pillars in the ancestral hall are engraved with several couplets, which are engraved with the words "Xianfeng" and "Guangxu".

Yu Baoying said that in this ancestral hall, some people have run steel needle factories and rice mills, and even stored incense sticks and broken objects. Three years ago, every time I went to Tomb-Sweeping Day, villagers would come here to worship their ancestors. Every time you worship your ancestors, you pull out the weeds inside and outside.

There are two explanations among the villagers about the mystery that there is no spider web in the old ancestral temple. Some villagers believe that this is because a very good day was chosen when the ancestral temple was built; It is also speculated that this may be because some special wood is used in the house, and spiders are afraid of the smell of this wood and dare not settle down here. But the villagers can't tell what kind of special wood is used in the house.

"Buildings without cobwebs like this have also been found in other parts of China, but no experts have analyzed it in detail." Chen, a professor at the Institute of Applied Insects of Zhejiang University, said.

According to Chen's understanding, there may be two reasons why spiders don't weave webs here: first, the ancestral temple has a clever structure, and spiders can't find a suitable fulcrum to weave webs; Second, as the villagers said, the ancestral hall uses special wood, such as camphor wood, which can drive away spiders. The smell of camphor wood will stimulate the brain cells of insects and keep them away. .
