This lavish gift is actually a sugar-coated bullet.
Tips
history
Coined by Mao Zedong in his March 1949 report to the Second Plenary Session of the Seventh Central Committee, warning that after victory the Party would face attacks 'wrapped in sugar coating' (糖衣裹着的炮弹), bribes, flattery and bourgeois comforts. The phrase became standard anti-corruption shorthand.
usage
Strongly political register. Used in Party / government anti-corruption discourse and serious news writing; sounds heavy in casual speech, where 诱惑 or 套路 would fit better.
