In a woman's birth chart, the Official Star represents her husband. If the Official Star is absent from her chart, it usually indicates that she has a weak connection with her future husband, resulting in fewer chances of meeting a suitable partner, which is very unfavorable for her marriage. It is generally necessary to look at the major life periods and annual trends. Only when these periods or years activate the Official Star can there be hope for marriage. If the Official Star does not appear in the major life periods, then she may become a "leftover woman" and even face a life without marriage.

The Official Star in a woman's birth chart represents her husband. However, some women have multiple Official Stars in their charts. This creates problems, as having too many Official Stars means she has many opposite-sex partners. A high number of husbands in the chart definitely affects her marriage. Often, she becomes indecisive between different partners, finding none satisfactory, and ends up waiting too long, which is one of the main reasons why women become "leftover women." Additionally, some women with too many Official Stars have good relationships with the opposite sex, which can have a fatal impact on their lives. Many women in special professions fall into this category.

The four pillars of the birth chart—year, month, day, and hour—each contain two characters, making a total of eight characters. Each pillar represents a different time period in life: the year pillar represents ages 1–16, the month pillar represents 16–32, the day pillar represents 32–48, and the hour pillar represents 48–64. From these time periods, we can see that if the Official Star is located in the year or month pillars, a partner tends to appear early. If the Official Star is in the day or hour pillars, a partner appears later, leading to the possibility of becoming a "leftover woman." Many women who marry late often fall into this category.

In the birth chart, the balance of the five elements is crucial. Only those with strong elements can form a solid structure, while weak elements cannot hold. If the Official Star in a woman's chart is too weak, it will be difficult for her to maintain a stable relationship. Furthermore, the Official Star should not be attacked, clashed, or buried in the chart. If the Official Star is in an unfavorable position, such as being in a state of decline, it is also a reason for unstable marriage. Many women date for a long time but ultimately fail to find a suitable match, and most of them fall into this category.

Food and Injury Stars are the stars that represent what you produce in your chart. These stars are capable of weakening the Official Star, which represents the husband. Therefore, they are harmful to a woman's marriage. Especially the Injury Star, which has a strong destructive power. Many women who have this star in their chart focus entirely on their careers, showing little interest in the opposite sex and neglecting their marriage. As a result, they unknowingly become "leftover women." These women are often educated, career-oriented, and capable individuals. This is one of the reasons for the emergence of "leftover women." Additionally, many women experience multiple marriages in their lives, and some lose their spouses in middle age, which is typically due to this type of chart configuration.
