After buying groceries, Gu Chen drove back to Old Hu's shop.
He wanted to say hello, but seeing Old Hu busy repairing a car, he felt it wouldn't be right to disturb him.
He turned off the engine and got out of the car.
He silently tucked a hundred yuan bill under the windshield wiper as if he were issuing a parking ticket.
The reason he did this was that he knew if he just handed it over directly, Old Hu would definitely not accept it.
After all, this was a man who even thought to share his cigarettes with someone else.
But without Old Hu, he wouldn't have met Old Zhao.
Nor would it have been possible to get a twenty-percent share for free.
The world is round; when you help others, you very likely end up helping yourself as well.
This is probably what they mean by, "Help others and you help yourself; what goes around, comes around."
...
Time flies, and before he knew it, it was already past one o'clock.
