In China, women can get married at the age of 20. Article 6 of the Marriage Law stipulates that the age of marriage shall not be earlier than 22 for men and 20 for women.
The legal age for marriage refers to the minimum age for marriage prescribed by law. In other words, men and women cannot marry until they reach this age. They can only marry when they reach or exceed this age. As for the maximum age for marriage, there is no limit.
