I still need to ask for your guidance on this matter, respected elder.
Tips
register
您老 stacks two honorifics: 您 (the polite 'you') + 老 (a respectful tag for elders). It's used by the young addressing a much older or higher-status person — e.g. addressing an elderly customer, a teacher's father, or a venerable craftsman. Very common in Beijing speech and period dramas.
mistakes
Don't use 您老 for someone close to your own age — it sounds either fawning or sarcastic. For peers, plain 您 is enough; among friends, 你.
