In Asia,
People always loved to have a male child over a female child.

Normally,
Our argument was, if you have a girl child you are having so many commitment but boy means less commitment….Right

It’s totally wrong….

Let us see the hidden factor from the father angle,
If a father expecting a boy means he knows very well that he is going to bring a girl (daughter-in-law) into the family as a bride. Now the family becomes complete there is always a continuation of male and female in their family, giving a feeling of complete family.
If it is a girl, what the father does is pamper his daughter to the end because he knows very well she is going to leave him and to join her in-law family, forgetting the root and creating her own root in her husband’s family.

Another factor If the father has a daughter, he is happy that he has to only have a good amount of money in order to spend for her education and for her personal expenses but If he has a son, then he has an additional responsibility of creating a structure for his future income. 
1. If the father is a businessman, he has to train his son along with studies, to make him take over his business to live a good life.
2. If the father is a salaried one, he will see to it that his son chooses the best form of education and gets employed in a reputed firm.

Hence having a son is more boring than having a daughter
But son’s complete the family by bringing a daughter to his father rather than a girl moving away to have a family.
