Girls enjoy full freedom. "They pass the time by joking, drinking tea, smoking, making up and attending various ceremonies", but "once married, that kind of unrestrained life will come to an end" and "married women should fulfill their responsibilities as wives and mothers". In other words, trimming your eyebrows and dyeing your black teeth "is proof that you have completely abandoned your previous vanity and enjoyment." In other words, this phenomenon is a manifestation of the age ladder mechanism in civilization, which is very similar to the age ladder system of Masai people in essence. Young Masai who fully enjoy freedom and even allow deviant derailment will become elders who maintain tribal order with eloquent eloquence and accurate judgment. In fact, dyeing black teeth does not protect women's chastity, but is only a symbol of the age ladder system for those married women. Of course, it may also include the significance of protecting women's chastity. But chastity cannot be preserved by the system.
The typical East African age ladder system displayed by Masai and Guki people divides life into several stages according to age, and endows each stage with unique behaviors and corresponding rights and obligations. It is a complete life and belongs to an interdependent social system. In other words, life develops in stages in this system. Dyeing black teeth is only a symbol that women belong to a certain age group. Although it also contains the meaning of chastity, it has not actually become an institutional barrier to protect women's chastity. Dyeing black teeth and shaving eyebrows did not play a substantial role in keeping married women away from the temptation of the opposite sex as Europeans and Americans imagined. Women who dye their black teeth and shave their eyebrows are different in sexiness and attractive to men. This can be known from Ge Mo's spring paintings. This is a symbol of a woman's role change from a young girl to a good wife and mother, that is, she has taken a new step to the end in the whole life process.
