Exchanging Medicine for Medicine

"Everyone, please calm down." Perhaps Yun Nian's decisive reprimand of the unscrupulous shopkeeper had left a lasting impression, as her words carried an air of authority and credibility, instantly silencing the clamoring crowd.

"From today onwards, Bai Cao Tang will be renamed Ji Shi Tang, symbolizing our commitment as healers to aid the world. The ten copper coins are merely a token of trust. For those who cannot afford the payment, Ji Shi Tang will also accept medicine in exchange."

As soon as these words were spoken, questions arose from the crowd. "What do you mean by 'exchanging medicine'?"

Yun Nian explained, "I believe everyone is familiar with the barren mountains outside the city. They are abundant with medicinal herbs. For those who cannot afford to buy medicine, they can gather herbs from the mountains and exchange them for the remedies they need. This way, we can establish a fair and equal exchange."
