This miracle event took place in China, in the city of Xiamen. When the couple's twins were born, the father saw that one of them didn't look like him at all.
The results were definitive: the baby who didn't look like him wasn't his son - but the other 'twin' was.
In fact, the babies were not twins at all, but half-brothers of exactly the same age. This phenomenon is called superfecundation, meaning that both babies were conceived around the same time, but not by the same man. A shocking way to discover that his wife was unfaithful.
