A man from China's Sichuan province sought the help of an ancient Chinese DNA test to confirm his son's identity.<br /> <br />The suspicious father started having doubts when he noticed that his one-year-old son was born with "single eyelids" while both he and his wife have double eyelids. The disparity in their resemblance prompted him to question his wife's fidelity.<br /> <br />One morning, after his wife left, he took a bowl of water, and dripped a drop of both his and his son's blood into it. According to ancient wisdom, the child is confirmed to be the father's if the blood droplets merge.<br /> <br />His wife was outraged by his stupidity when she learned of the test and left him, taking the baby with her. A certified DNA test later confirmed the son as his child.
