If Dr. Yang was an old man in his seventies or eighties, then he would only need to repay his kindness for more than ten years and twenty years. When he was thirty or forty, his gratitude would have been repaid, but now, he realized that the other party was actually a young man, how many years would it take for him to repay the gratitude?

Eh?

No, he shouldn't be feeling happy
