"There was no Chinese Pinyin in ancient China," Yuan Shucai said, holding on to the diagram that Zhao Yu had handed to him. "People during that time used the pitching method, which involved using two words to form the pitch of how a word sounds. The so-called Ghost Eight Diagrams is actually a long-lost phonetic notation method."
"Oh?"
Zhao Yu was impressed and his eyes lit up. As the saying goes, "Every trade has its master", although Yuan Shucai was from a peasant origin, and did not even attend elementary school, he mastered so much knowledge through his own efforts. Such perseverance was indeed inspiring. However, it was a pity that he applied his knowledge in such a wrong way."
