Mrs Afu (Takechiyo's wet nurse) is a famous wet nurse and female politician in Japanese history. She was born in the middle of17th century, formerly known as "Chiyo", and was adopted by Takechiyo, the wet nurse of the second generation general of Tokyo shogunate. She became Takechiyo's wet nurse, known as "Takechiyo's wet nurse" and later as "Takechiyo's wet nurse".

According to historical records, Mrs. Afu is kind, intelligent and capable. She was trusted and valued by General Tokugawa Guang Jia for many times, and gave birth to two sons and a daughter, becoming an important figure in the domestic management and political intervention of the general's family. She is proficient in politics and military affairs, with outstanding wisdom and insight, and has repeatedly provided important suggestions for the political decision-making of generals and shogunates.

Mrs. Afu has far-reaching political influence. At her suggestion, the shogunate carried out a series of reforms in foreign policy and carried out the policy of "closing the country to the outside world". In addition, she also participated in the shogunate's school management and religious policy, which played a positive role in promoting the social and cultural development in the Edo era.

Although Mrs. Afu is respected and admired by many people, she is also controversial because she broke the social rules that men are superior to women and became a rare female politician in this era. Some people think that she overstepped her authority and gained extra power, while others think that she is a symbol of women's liberation and a political leader.

In a word, Mrs. Afu is a legendary historical figure, and neither her personality charm nor her contribution to the development of Japanese politics and culture can be ignored.
