A rural and small Chinese village has been in the media spotlight because of a mysterious cliff face that is said to lay ‘eggs’.
The so-called ‘egg-laying cliff’, situated in south-east China, regularly produces large round rocks as heavy as 660 pounds, according to the locals.
It’s said that the ‘stone eggs’ would drop from the cliff once every three decades or so. Scientists are yet to give an official explanation to the phenomenon.

The unusual mountain is located in the Guizhou Province in the Gulu Zhai village, where the minority Shui People have lived for about 1,000 years.
According to a previous report on DW News, the ‘egg-laying cliff’, or ‘chan dan ya’ in Chinese, is an area measuring 20 metres long (66 feet) and six metres wide (20 feet) on an unnamed mountain in the village.
‘Stone eggs’ would reportedly grow from the cliff face and eventually drop to the ground.
The local residents believe that the ‘stone eggs’ could bring them good luck, so they would collect the rocks and worship them at home. They have reportedly collected over 100 of them
The spheres have a diametre between 30 and 60 centimetres (11.8 inches and 23.6 inches) and could weight up to 300kg (660 pounds).
These rock spheres are thought to be lucky by the residents, who would pick them up and worship them at home.
A recently video report on QQ.com claimed that every 30 years or so, the ‘mature eggs’ would fall to the ground.
The report said the ‘stone eggs’ appeared dark blue in colour and looked like dinasour eggs. The video said when the journalists arrived, some of the eggs had just ‘started to grow’ while others seemed to be ready to drop.
There are more than 100 families living in the village and they had reportedly collected more than 100 ‘stone eggs’.
They believed that the objects would bring good luck to their lives and help the newly wed couples have baby boys.
Although the mysterious phenomenon has been widely reported in China, scientists are yet to give an official explanation to it.
WHY DOES THE CLIFF ‘LAY EGGS’?
Over the years, geologists in China have provided some possible explanations to the cause of the phenomenon. However, none official ones have been announced.
The ‘stone eggs’ were lumps formed by calcium carbonate molecules in the deep sea around 500 million years ago during the Cambrian Period, claimed Dr. Wang Shangyan from the Bureau of Geology and Mineral Exploration and Development of Guizhou.
In a book, called ‘Scary Phenomena’, Dr Wang said the deep sea turned into high mountains over time, and these lumps became lodged in the mountains.
And because mudstone, which forms the mountains, weathers more quickly than the lumps, it appears that the cliff is giving birth to the ‘eggs’.
Dr Wang’s opinion was largely agreed by Professor Xu Ronghua from Institute of Geology and Geophysics, Chinese Academy of Science.
But Prof. Xu said the lumps were made with silicon dioxide.
In explaining why the objects are round, Prof. Xu told DW News: ‘A sphere has the smallest superficial area compared to other shapes with the same volume. As such, it would take the least effort for the molecules to form a sphere than the other shapes. ‘
Prof. Xu said running water could also be a factor why the lumps are round.
He added that similar phenomena had been observed in Beidaihe, north China, and Xinjiang, north-west China.
