倾他城入他心倾她国占她心
[qīng tā chéng rù tā xīn qīng tā guó zhàn tā xīn]
Loosely translates to 'Capture a City in His Heart and a Country in Her Heart.' Drawing from classic Chinese romantic expressions about conquering hearts as vast as cities and nations; it conveys the intensity of making someone profoundly impacted emotionally or romantically.
