不到最后一刻不松口不到最后一刻不放手
[bù dào zuì hòu yī kè bù sōng kŏu bù dào zuì hòu yī kè bù fàng shŏu]
'Never give up until the last minute.' This phrase conveys determination and perseverance. It describes someone who won’t relinquish or admit defeat easily; they will fight till the end and not loosen their grip under any circumstances unless it’s absolutely necessary.
