Introduction
Different lucky stars can still be together. If both of your eight characters can complement each other (such as you lack what I have, and I am weak while you are strong), it may even be more harmonious. Having the same lucky stars is not the only standard for a true match. A true match should be based on the overall compatibility of the eight characters (such as the day pillar generating each other, without serious conflicts), rather than just looking at whether the lucky stars are the same.

Can people with different lucky stars be together?

People with different lucky stars can indeed be together, and in some cases, a "complementary" relationship may be more stable.

The core of the eight-character marriage compatibility is "five-element balance and mutual support," not that the lucky stars must be the same. For example, if one person's lucky star is fire but their fire element is weak, and the other person has a strong fire element and fire is not a taboo element (i.e., not an enemy), then the strong fire can help the other person supplement their lucky star. For instance, if one person needs fire to boost their career, the other person's fire energy can indirectly bring them good fortune;

If one person's lucky star is wood and they are against metal, and the other person's lucky star is metal but the metal is weak and there is no strong metal that could harm the wood, the two will not have serious conflicts. On the contrary, if the lucky stars are the same but both are overly strong (e.g., both like wood and their eight characters have too much wood), it may lead to competition (e.g., competing for opportunities in their careers) or conflicts due to stubbornness.

As long as the two people's eight characters do not have serious conflicts (such as the day pillar clashing or the seven killing element attacking the main element), they can live in harmony even if their lucky stars are different.

Is having the same lucky stars the only standard for a true match?

Having the same lucky stars is not the only standard for a true match. A true match requires the overall eight characters to be "mutually supportive and harmonious, without major issues."
A true match is about "long-term comfort and mutual support." It should be evaluated comprehensively based on three aspects: first, the interaction between the day pillars (if the day pillars generate each other, such as jia wood generating ding fire, or ji earth generating geng gold, the relationship will be more harmonious; if the day pillars are compatible, such as zi chou combination or yin hai combination, the connection will be deeper);

Second, there should be no serious conflicts (for example, if one person's seven killing element is strong and attacks the other's main element, it may lead to conflict; if one person's seal element is weak and the other's injury element is strong, it may affect family harmony);

Third, the five elements should complement each other (even if the lucky stars are different, if they can make up for each other's shortcomings, such as one person being weak in water and afraid of fire, and the other person having strong water to balance it, it can also form a true match).

Having the same lucky stars may allow both people to have common goals (such as both liking wood and wanting to grow and learn), but if the overall characters are not compatible, just having the same lucky stars cannot guarantee a true match. Conversely, if the lucky stars are different but the characters are complementary, it may be easier to become a long-term partner.

Related Questions
Question One: Can people with different lucky stars and one person being harmful to the other still be together?
It depends on the "strength" of the harm: if it is only a slight harm (such as one person's official element being weak and harming the other's day pillar), and there is an imprint element to resolve it (such as the imprint element neutralizing the official and killing elements), it can be alleviated through postnatal adjustments (such as living separately and communicating more). If it is a strong harm (such as one person's seven killing element being strong and uncontrolled, harming the other's day pillar), it may lead to serious conflicts (such as health problems or broken relationships), so it needs to be carefully considered.

Question Two: If people have the same lucky stars but their eight characters clash, is it a true match?
It is unlikely to be a true match. Clashing (such as the day pillar zi wu clash or the month pillar yin shen clash) disrupts the energy of both sides, leading to frequent conflicts in the relationship (such as personality differences or ideological conflicts). Even if the lucky stars are the same, the clash may prevent the "common goals" from being achieved, making long-term coexistence tiring. They are more suitable to be friends rather than partners.
【Conclusion】Lucky stars are just a "small dimension" in eight-character marriage compatibility. Whether they can be together and whether they are a true match mainly depend on whether the overall eight characters are complementary and harmonious. Even if the lucky stars are different, as long as they can compensate for each other's shortcomings and avoid serious conflicts, they can still live happily and long-term;

If the lucky stars are the same but there are clashes and conflicts, it may not lead to a good outcome. Remember, divination is a reference, and the key to a lasting relationship lies in understanding and tolerance in the postnatal stage.
