干掉妃子我就是皇后干掉太子我就是皇上
[gān diào fēi zi wŏ jiù shì huáng hòu gān diào tài zi wŏ jiù shì huáng shàng]
Literally 'Kill the concubine and I become Empress; Kill the Crown Prince and I become Emperor.' It expresses ambition without scruples, indicating someone's determination to reach their goals, no matter how high, through any means necessary – even violent ones.
