Li Shizhen's Apprentice Xuan Zhen and I Were Colleagues

When Azhen was eighteen years old, she was sold by trafficker Zhu Laoliu to Teng Tiao, the son of a mountain villager's grandmother in Fairy Mountain. The next year, she gave birth to a boy, Shan Ya Zi. One day, Shan Yaozi, who was less than one year old, was sleeping. An old man with a white beard wearing a long gown stepped on the auspicious clouds from the top of the fairy mountain and came to Shan Yaozi. He stroked Shan Yaozi's head and gave Shan Yaozi a medicine book. He told Shan Yaozi to study it carefully and treat diseases for the people of Li when he grew up. When Shanyaozi was five years old, Azhen left without saying goodbye with her two-year-old sister. As a result, Shanyaozi's father, Tengjue, became mentally disturbed. From then on, Shanyaozi depended on his grandmother, grandpa Shanbo, and his mentally disturbed father Teng Tiao. Twenty years later, Shan Yaozi became a famous pharmacologist.
