The ancient Chinese people are so clever that they had many interesting discoveries, and the chinese pregnancy calendar is one of them.
This chart was buried in a royal tomb approximately 750 years ago, and now it is known as "Baby Gender Chart" or "Chinese Birth Charts". The original chart can still be seen now at the Beijing Institute of Science in China.
The Chinese Pregnancy Calendar was thought to have been created to give parents to choose their baby's gender. According to the mother's age, if they conceive their baby at a certain time of year, they can choose a boy or girl then.
The ancient Chinese people discovered this chart because the sex of the baby was the most important thing for many parents, and it is still an issue to many Chinese people today in many places!
Of course, now we can use this Chinese pregnancy Calendar chart just for fun! The sex of our baby can be known through the more accurate ways such as 3d scan, or ultra-sound scans!
However, the Chinese Pregnancy Calendar has a quite higher score - some people say that it is more than 50% correct!
How clever the ancient Chinese people is!
