What two tactics did Mongols warriors use to scare people into surrendering?

Mongol warriors often employed psychological warfare to instill fear in their enemies, including the use of brutal tactics such as mass killings and the destruction of entire cities to demonstrate their power. They also utilized swift and unpredictable cavalry maneuvers, creating a reputation for relentless and overwhelming attacks that made surrender seem like the only option for survival. Additionally, they sometimes spared the lives of those who surrendered, further amplifying the fear of resistance and encouraging others to capitulate without a fight.
