Facing Zhang San's explanation, everyone naturally didn't believe it.
What are initials and finals? What are these things!
So, Zhang San started phonetic teaching on the spot.
"For example, the grass on the ground is a combination of 'c' and 'ao.' For instance, the mud on the shoes is a combination of 'n' and 'i.' For example..."
At this moment, although everyone was baffled by the unheard-of terms of initials and finals, they slowly realized through Zhang San's examples that Zhang San's Forty-Eight Layers Tower, just by conceiving these initials and finals, could produce all characters.
The Twelve Layers Tower of Legalism contained only twelve characters.
Zhang San's Forty-Eight Layers Tower contained everything!
As everyone started to understand initials and finals, they also began to try forming characters they were familiar with.
