Guan Mucun's mother, Li Fang Mi, was born in a big family in Xinxiang, Henan. She is a beautiful and kind woman with higher education. She works in a bank, but she loves music. Grandpa doesn't like girls singing and dancing outside, so he invited a European music teacher to teach his mother to play the piano and sing bel canto. But he must entertain himself and sing in family gatherings and friends' circles, and he is not allowed to sing outside. After liberation, the capitalist's daughter could not enter the banking system, and her mother became a music teacher.
