Teaching dad about business formulas for 4 hours, using different methods, but he still struggles to grasp it. Only through practical exercises did he start to understand. Realized the importance of keeping the brain active to prevent cognitive decline. Now taking the role of teaching parents to stay connected with the modern world.

Turnover period = Store establishment cost / Monthly operating profit
Recovery period = Store establishment cost / (Monthly operating income - Monthly operating cost)

Two simple formulas, taught my dad for 4 hours, used numerical deduction, strong memorization, and scenario practice, but dad still couldn't fully grasp it.

Only the final scenario practice gave him some feeling. Dad has a period of addiction to short videos without using his brain, but I didn't expect his logic and comprehension abilities to deteriorate so severely, like two different people from his younger days. Fortunately, I discovered it today.

The brain will deteriorate if not used. I really don't want my parents to be out of touch with this era. What they taught me little by little when I was young, I am now turning around to teach them.``
