变心的灵魂叫做傀儡
[biàn xīn de líng hún jiào zuò kuĭ lĕi]
"A Changed Heart Soul is Called a Puppet": The soul refers to one's core beliefs or emotions; changed heart means losing one's true self and values. People who abandon these are compared to soulless puppets, just following commands, no longer having real feelings or willpower.
