九命猫不灭一颗心
[jiŭ mìng māo bù miè yī kē xīn]
It literally means 'the nine-lives cat is not quenched by a single heart.' In Chinese culture, a nine-lives cat is often associated with someone who is very hard to die or extremely adaptable. Here it metaphorically says that a resilient spirit or strong willpower cannot be extinguished easily by just one person (or love).
