执手弄青梅转眼即逆夏
[zhí shŏu nòng qīng méi zhuăn yăn jí nì xià]
Based on the classical expression 'qing mei zhu ma you' that evokes childhood memories of close companionship. The added phrase signifies a nostalgic view towards fleeting childhood friendships which turn upside down or end prematurely, reflecting bittersweet reminiscence.
