入他心做他后攻她城做她王
[rù tā xīn zuò tā hòu gōng tā chéng zuò tā wáng]
Translating as 'Enter his heart be his support, invade her city become her king.' It suggests taking deep roots in someone’s affections while metaphorically becoming a protector/leader in someone else's life space; it implies emotional dominance or significance within relationships.
