Aladdin and his wife have been unable to conceive a child for many years, which has left the Princess feeling frustrated and anxious as they long to have a family and share their lives with a child. This situation can lead them to feel lonely and lost, especially when those around them have children and families.

Additionally, societal pressure and expectations to bear offspring can also cause stress and discomfort for the couple. In some cultures, having children is viewed as an important part of the family, and not having children can be seen as a failure or misfortune.

"Filial piety has three parts, and having no descendants is the biggest" is a traditional belief that emphasizes the importance of filial piety and family continuity. This phrase means that if a person is not filial to their parents and ancestors, and has no descendants to inherit their family and property, they will be considered very unfilial.

Although this belief is strong in some cultures, modern society has started to accept couples without children. Many couples choose not to have children for personal reasons or other preferences, rather than difficulties in conceiving. In this case, the couple can achieve satisfaction and happiness by focusing on other things, such as pursuing careers, traveling, and social activities.
