兲眞菿無葯可慦
[tiān zhēn dào wú yào kĕ jiù]
These are characters written in a decorative Chinese calligraphy style called Liushu, commonly used in internet slang. When translated into standard Chinese characters, it would mean ‘天真果无忧可爱’ (Truly innocent and lovable). This implies being simple-minded, pure-hearted, and endearing.
