1. Thank you for helping me when I was in trouble. If you have any questions, I will certainly help you.

I wouldn't have achieved great success without your timely help. Thank you, friend. If you encounter any difficulties in the future, just ask and I will do my best to help you.

3. At the beginning, giving charcoal in the snow warmed my life, and good people were rewarded. I wish you good luck and prosperity.
