Please translate a classical Chinese sentence given during fortune telling.

Simple translation (only rough translation):

It is not advisable to get married too early. The beauty and ugliness of a wife are beneficial, and Yin and Yang also need to help each other. Only in this way can a long-term relationship be maintained.

Don't understand?

Generally speaking, don't get married too early, and don't ask too much about your wife's appearance, which is beneficial to both sides. After marriage, both husband and wife should be soul mates and help each other, so that they can get along well for a hundred years and have a lasting foundation.
