August coin friends' life guide:
1. When picking up waste, the cardboard box must not be wet, otherwise the waste collector will not want it.
2. When selling water bottles, you can unscrew the lid and sell it separately, and the price of the bottle remains unchanged.
3. Aluminum cans are more expensive than plastic cans.
4. If you find a water bottle, you must crush it and not cause trouble for the waste collector. If you don't crush it, you will be targeted and have your money reduced.
