This is a wild one! A woman in China discovered that her soon-to-be daughter-in-law was her biological daughter.
The mother noticed a birthmark on the bride's hand, which looked similar to that of her long-lost daughter. She asked the bride’s parents if she was adopted and they confirmed that she was. The bride went missing 20 years ago and was picked up by her adoptive parents on the roadside.
The wedding would have been called off at this point, but the groom was also adopted, so the wedding proceeded as planned.
