空人空心空世界假情假意假温柔
[kōng rén kōng xīn kōng shì jiè jiă qíng jiă yì jiă wēn róu]
Literally translates as 'empty person, empty heart, empty world, fake feelings, fake gentleness.' This indicates feeling hollow inside with a lack of real emotional connections, where people around appear cold-hearted despite outward displays of affection.
