"What?" Liang Huang and another expert were shocked, and asked, "What do you mean wrong version? How come I've never heard of it?" Zhao Yu also craned his neck, confused.
"Broadcast Gymnastics stamp was a regular type of stamp," the older expert said. "The original plan was to release them in 1951. But after the post office made about ten-thousand copies or so, they suddenly realized that there was some mistake on the stamp, so they didn't release them that year, but destroyed them quickly! After editing, they finally released them in 1952!
"But, even though they recalled them quickly that year, according to rumors, there was a set or two that survived. Just how they survived was unknown. Even my teacher had only heard of them, but had never seen them!"
"Woah, isn't that incredible?" Liang Huan looked at the screen. "Sir, since no one had seen them, how could you know of them? Just how were they printed wrong?"
