Introduction to the Comparison Chart of Boys and Girls Born in the Qing Palace in 2022 The Comparative Chart of Boys and Girls Born in the Qing Palace, as the name suggests, uses the lunar calendar and the age of the woman to predict whether the unborn baby will be a boy or a girl. This technology originated from the concubines in the harem of the Qing Dynasty who wanted to give birth to a prince, and gradually spread among the people. It has now become a popular method for predicting the gender of a baby among parents at home and abroad. The comparison chart between boys and girls born in the Qing Dynasty has a relatively high accuracy and is simple and convenient to operate.
