With regard to the age of marriage between men and women, Article 6 of China's Marriage Law stipulates that "the age of marriage shall not be earlier than 22 for men and 2 for women". Where there are adaptations or supplementary provisions to the Marriage Law in ethnic autonomous regions, they shall be handled according to the adaptations or supplementary provisions. In addition, there are no other provisions on the marriage age of men and women in laws or regulations. From these regulations, we can see that the law only stipulates the minimum age for marriage between men and women, but does not stipulate the minimum (maximum) gap between men and women. We can say that marriage laws for men and women with great differences in age are not prohibited. As long as both parties are completely willing and comply with other provisions of the Marriage Law, you can get married.
However, we should also see that marriage is a legal natural union between men and women on the basis of love, and the marriage relationship generated by this union is based on the physiological differences and sexual instinct of men and women. You should really consider the differences in age, cultural background and values when choosing a marriage partner.
