   1. Bru Sang - breathing without noise, very soft and natural.
   2. Bru Gerl - breathing continuously, not stopping.
   3. Bru Joe - smooth, not rough, soft like cotton.
   4. Say Say Meun Meun - thin like silk.
   5. Yak You Yak Moo - continuously inhaling and exhaling, without any indication or feeling as to what state you are in.
