Su Binglan had taught Lin Zheng, Li Shi, and Zhou Shan martial arts, Arabic numerals, calculation, and accounting. She did that to train them as managers. She felt more at ease with them in charge.
When Zhou Shan heard Su Binglan's words, he became excited, "Don't worry, Boss. I'll study hard and make you proud.
Lin Zheng said, "Zhou Shan is excellent at accounting now, Master. He's also swift at it. Li Shi is the same. He studies for a long time every day when the shop closes."
Li Shi started to feel embarrassed. "Boss, Lin Zheng is the fastest learner here. He would teach us everything he knew whenever we asked him about something we didn't understand. That's why we can learn so quickly."
Zhou Shan added thoughtfully, "Yes, Boss. You taught us Arabic numerals, which makes our accounting much more efficient."
