奉生
[fèng shēng]
The direct meaning here would be respecting/obeying life. The word expresses respect and cherishment for their life. A user might choose this pseudonym to reflect a philosophical attitude towards facing all aspects of life -- including hardships and joy, successes and setbacks, illness, wellness, longevity, etc. They're devoted entirely, as though fulfilling a mission or obeying something supreme and irreplaceable: life itself.
