Zhang Xiaoniang was a famous folk female doctor during the five years of Jia in Northern Song Dynasty. According to legend, her magical medical skills were taught by the gods in the mountains, and she was given the book "Tonic Different Prescriptions". She is beautiful and intelligent, proficient in herbs, helping the weak and saving the weak, and her reputation is far spread. She is one of the four female doctors in ancient China.

Zhang Xiaoniang in Song Dynasty was a surgeon. It is said that an old doctor with silver hair and sideburns passed on her medical skills and gave her a book called Different Prescriptions. After continuous research and practice, she finally became a female doctor proficient in surgery. All patients with sores, ulcers, carbuncle and swelling came to see a doctor and were treated by Zhang Xiaoniang, all of which had miraculous effects. Later, both husband and wife became local famous doctors.

The secret recipe of beauty and skin care won the favor of women in the palace. When the concubines and the queen heard about this wonderful folk woman with superb medical skills, they called Zhang Xiaozi into the palace and asked Zhang Xiaozi for a house for beauty and skin care, so that she could keep her skin delicate and smooth and stay young forever. After that, Zhang Xiaozi took herself as the experimental object, and constantly concocted beauty beauty's secret recipe with Chinese herbal medicines, including face washing recipe, shampoo recipe, bath recipe, fragrant clothes recipe and jade noodle recipe, which were used by concubines in the harem and also solved various gynecological problems for them. Because of its remarkable effect, the secret recipe of beauty care has become the secret recipe used by aristocratic women and ladies-in-waiting, and she herself has become a gentle female doctor.

Emperor Renzong gave the name "Zhang Xiaozi". Emperor Renzong was overjoyed to see that the concubines in the harem were nursed back to health by Zhang Xiaozi's secret recipe, and their skin was as beautiful as flowers, white and smooth. Seeing that Zhang Xiaozi was over 30 years old and still looked like an 18-year-old virgin, Emperor Renzong called Zhang Xiaozi "Doctor Saint" and named her "Zhang Xiaozi". In the Tang and Song Dynasties, men called young and beautiful women "little ladies" whether they knew each other or not. Emperor Renzong gave the name, which means that the little lady Zhang is skilled in medicine and can rejuvenate women and keep their youth and beauty forever. )
