余栀清香
[yú zhī qīng xiāng]
These characters are combined aesthetically rather than conveying a direct literal meaning. 'Yu (余)' indicates surplus or lasting; 'zhi(栀)' is probably an abbreviation from words like gardenia; 'qing xiang (清香)' means fresh fragrance, often describing scent but also implying the purity and delicacy of a person's character or style.
