今夜春宵一夜千金
[jīn yè chūn xiāo yī yè qiān jīn]
Literally, it means 'Tonight, a spring night, is worth thousands of gold pieces', suggesting tonight would cost a lot due to romance or luxurious spending during special times, like newly married couples' first night. 'Spring night' sometimes implies romantic or erotic situations, especially in old-fashioned contexts. The expression connotes a precious, unmissable opportunity full of anticipation for pleasure and excitement.
