The C&O logo is compound Chinese character.
 
It is a combination of 'Chi' and ‘li’
 
‘Chi’ symbolises effort, strength, integrity
 
And "li" lends itself to an attitudinal orientation, an ability to transcend all obstacles and turn the tide in one's favour
 
The color orange signifies the dynamism and vitality of a flame, typifying the burning passion that consumes CNO to excel at everything it does.
 
As a balance against this, the Olive Green color of the character itself stands for stability, endurance, dependability, peace, harmony and the green earth.
