She entered the deep palace as her eldest sister's dowry maid, and relied on her keen observation and modern thinking to navigate the turbulent palace battles step by step. She does not rely on golden fingers, but uses information gaps, people's hearts and the art of checks and balances to start by exposing small conspiracies and gradually accumulate strength.
