The jewel in the palm of left prime minister Mu Qing - the twin jewels of the Mu family. Legend has it that they can speak in three months, walk in one year, and write poems in three years. Both of these two people are regarded as the apple of the eye by the left prime minister. Although they were born from the same mother, same year, same month and same day, they look different. Legend has it that when they were born, there were phoenix clouds hovering over the Mu Mansion. Two concubines gave birth to daughters and became the focus of the Xiuyue Dynasty.
