Water symbolizes wealth, and rain is also a type of water. Folk beliefs hold that the more and heavier the rain when the child is born, the more prosperous the child's future wealth will be, making it easy for the child to become a wealthy person. Therefore, this is considered a very auspicious sign. Parents should therefore be more dedicated in raising their children, so that the child can become rich and successful in the future.

It is good if it rains or blows wind when the child is born. In folk customs, it is believed that if a child is born during wind and rain, it means the child will have a good fate. In the past, people's agricultural development relied on nature, and rain was essential. Therefore, what many people might see as bad weather—wind and rain—actually has a positive meaning.
