"Then just take 20 yuan. If you have it, toss it here, if not, we can talk about it some other day."
"Doctor Liu, you've really saved my life. How could I not pay you? Don't worry."
As he spoke, he fumbled in his pocket for a long time until he finally managed to gather 20 yuan, which he casually threw onto the table.
"Master, these last few days, I've suddenly realized that your prices are so low. Sometimes, for a prescription for the common cold or fever, it costs only about three to five yuan."
"Yes, don't forget, this is the countryside. Besides, these people are all farmers who spend their days working the soil. They labor all year round and don't earn much money. I can't be demanding money from them. So, I generally only charge them the cost price. Moreover, as you can see, most of the medicines are formulated by me, and they barely cost anything at all."
