What is the saying that Tibetan women get married after the age of 25? What's the point of a living Buddhist woman getting married?

First, Tibetan areas are very large, which can be divided into Amdo, Weizang and Kangba by language; By region and life: pastoral, agricultural and forest areas; Affected by climate. . . . In addition, there are some small branches of Tibetans, such as Baima Tibetan, Muya Tibetan and Shannan ethnic group. There are many differences in customs with the main Tibetans. Fourth, most living buddhas (to be exact, reincarnated soul children, called Zugu in Tibetan) are forbidden to get married and start a family according to the precepts. Only a few living buddhas in Ma Ning can get married.
