别流泪敌人会笑别低头皇冠会掉
[bié liú lèi dí rén huì xiào bié dī tóu huáng guān huì diào]
'Don't cry - the enemy will laugh, don't bow down - the crown will fall off', warning one against weakness and reminding them that they should be confident and stay strong in adversities to avoid being ridiculed by their opponents.
