Tips
usage
老 here is honorific (familiar respect, not 'old as decrepit'). 前辈 alone means 'senior/predecessor'; adding 老 emphasizes warmth and long standing - like 'old hand' or 'grand old man' in English.
register
Polite and slightly formal. Common in martial arts circles, academia, the arts, and traditional crafts where seniority and lineage matter.
