HISTORY OF THE CHINESE GENDER CHART
Ancient Chinese secret? When it comes to guessing baby gender, supposedly so. The Chinese Gender Predictor is said to have been based on I Ching, or the “Book of Changes,” and relies upon the Five Elements, Yin and Yang and the Eight Trigrams.

One legend says the more than 300-year-old Chinese Gender Chart was relied on by the Qing Dynasty imperial family for the gender selection of sons, of whom were favored for the work and money they could provide their families, as well as for carrying on the family lineage. Another tale says the Chinese Gender Predictor was found stored in an ancient royal tomb. But with a bit more digging, testimony from contemporary experts and our own fact-finding Chinese Gender Chart mission, we couldn’t find hard evidence to back either history.


HOW ACCURATE IS THE CHINESE GENDER PREDICTOR?
With origins as questionable as they are, it’s hard to rate the Chinese Gender Chart accuracy with any confidence beyond a standard 50/50 prediction. Some say the Chinese Gender Predictor is 90 percent accurate, but the research and related math don’t quite validate those stats. In fact, the few who’ve done a deeper dive studying the Chinese Gender Predictor have shown the accuracy to be as low five percent and as high as 55 percent, which makes it about as reliable as a coin toss.
