Name

This is the hanja for "saram" or "people". It is what Dr Oh was explaining. 

Each individual person is weak, so we lean on each other

just like each stroke on this word.

Huruf "人" adalah huruf awal dari kata "Saram (사람)" dalam bahasa Korea yang artinya "Orang (Manusia)".

Sama seperti setiap goresan kata ini yang saling bersandar, setiap manusia adalah individu yang lemah, itulah mengapa setiap manusia saling bergantung satu sama lain. Karena lemah, mereka bersatu

Manusia hidup saling bergantung satu sama lain.

Karena lemah, mereka bersatu.
