The staff's explanation of this phenomenon

It is understood that this 17-hole bridge was built during the Qingyi Garden period, spanning between Kuluting and Nanhu Island, and is the only land bridge leading to Nanhu Island. In order to explain the phenomenon of "golden light piercing the hole", the staff consulted a large number of historical materials, especially those related to bridge and light, but no historical materials mentioned any records about bridge and light.

"There is no astronomical basis, just a common landscape. Because around the winter solstice, when the height angle of the sun reaches the minimum, the light presents an oblique light and shadow, which can shine on areas that are not normally illuminated. From winter to a month or two before and after, you can see the beautiful scenery of the golden light of the bridge. " The above staff said.
