安静的脸

A yellow face placing an index finger over pursed lips, as if issuing Shh! or Shush! for silence. Some platforms feature raised eyebrows. Apple’s design suggests the face is tilting back slightly. 

May convey silence, quiet, secrecy, and discreetness. May also create a sense of buzz and anticipation, e.g., an exclusive sneak peek or news scoop.
